Michael Edward Peskin (born October 27, 1951, Philadelphia) is an American theoretical physicist. [1] He is currently a professor in the theory group at the SLAC National Accelerator Laboratory. [2]

Contents

Peskin has been recognized for his work in proposing and analyzing unifying models of elementary particles and forces in theoretical elementary particle physics, and proposing experimental methods for testing such models. [3] [4] Peskin was elected to the American Academy of Arts and Sciences in 2000. [3] He was appointed a co-editor of the journal Annual Review of Nuclear and Particle Science as of 2023. [5]

Education

Michael Peskin is a fourth generation descendent of Jewish Lithuanian emigrants from the Pale of Settlement. Both of his parents became medical doctors. Peskin attended Lower Merion High School in the Philadelphia area and later New Trier West in the Chicago suburbs. [6]

Peskin was an undergraduate at Harvard University. He obtained his Ph.D. in 1978 at Cornell University studying under Kenneth Wilson. He was a junior fellow at the Harvard Society of Fellows from 1977–1980. [6]

Career

After receiving his Ph.D. from Cornell University, Peskin served as a junior fellow of the Harvard Society of Fellows from 1977 to 1980. [7] He also held postdoctoral appointments at Saclay Nuclear Research Centre (1979-1980) and Cornell (1980-1982). [8] [6] In 1982, Peskin joined the faculty of the SLAC National Accelerator Laboratory at Stanford University. [9]

In 2000, Peskin was elected to the American Academy of Arts and Sciences. [3] He was appointed a co-editor of the journal Annual Review of Nuclear and Particle Science as of 2023. [5]

Research

Peskin has worked on many aspects of quantum field theory and elementary particle physics, exploring and going beyond the Standard Model of particle physics to explore technicolor theories. [10] Peskin and Schroeder's widely used textbook on quantum field theory, An Introduction to Quantum Field Theory (1995, 2018) is considered a classic in the field. [11] [12] [13] More recently, he has written Concepts of Elementary Particle Physics (2019), a textbook on the Standard Model. [14]

In 1990, Peskin and Tatsu Takeuchi proposed the parameterization of a set of three measurable quantities, called S, T, and U, that are used to describe and simplify precision electroweak fits. These parameters are sensitive to new physics which contributes to oblique corrections. [15] [16] [17] [18] They are now called the Peskin–Takeuchi parameters. [19]

Peskin uses high energy colliders to search for new physical interactions on the basis of high-precision observations and measurements of elementary particles, including the W and Z bosons, the top quark, and the Higgs boson. [20] [21] [22] [23] He is interested in modelling dark matter [24] and is a noted advocate of building a future linear collider, [25] [23] a “Higgs factory”. [1]

<span class="mw-page-title-main">Elementary particle</span> Subatomic particle having no known substructure

In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model presently recognizes seventeen distinct particles, twelve fermions and five bosons. As a consequence of flavor and color combinations and antimatter, the fermions and bosons are known to have 48 and 13 variations, respectively. Among the 61 elementary particles embraced by the Standard Model number electrons and other leptons, quarks, and the fundamental bosons. Subatomic particles such as protons, neutrons or muons, which contain two or more elementary particles, are known as composite particles.

<span class="mw-page-title-main">Particle physics</span> Study of subatomic particles and forces

Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions and bosons. There are three generations of fermions, although ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction.

<span class="mw-page-title-main">Standard Model</span> Theory of forces and subatomic particles

The Standard Model of particle physics is the theory describing three of the four known fundamental forces in the universe and classifying all known elementary particles. It was developed in stages throughout the latter half of the 20th century, through the work of many scientists worldwide, with the current formulation being finalized in the mid-1970s upon experimental confirmation of the existence of quarks. Since then, proof of the top quark (1995), the tau neutrino (2000), and the Higgs boson (2012) have added further credence to the Standard Model. In addition, the Standard Model has predicted various properties of weak neutral currents and the W and Z bosons with great accuracy.

In a supersymmetric theory the equations for force and the equations for matter are identical. In theoretical and mathematical physics, any theory with this property has the principle of supersymmetry (SUSY). Dozens of supersymmetric theories exist. Supersymmetry is a spacetime symmetry between two basic classes of particles: bosons, which have an integer-valued spin and follow Bose–Einstein statistics, and fermions, which have a half-integer-valued spin and follow Fermi–Dirac statistics.

<span class="mw-page-title-main">Top quark</span> Type of quark

The top quark, sometimes also referred to as the truth quark, is the most massive of all observed elementary particles. It derives its mass from its coupling to the Higgs Boson. This coupling is very close to unity; in the Standard Model of particle physics, it is the largest (strongest) coupling at the scale of the weak interactions and above. The top quark was discovered in 1995 by the CDF and DØ experiments at Fermilab.

<span class="mw-page-title-main">Technicolor (physics)</span> Hypothetical model through which W and Z bosons acquire mass

Technicolor theories are models of physics beyond the Standard Model that address electroweak gauge symmetry breaking, the mechanism through which W and Z bosons acquire masses. Early technicolor theories were modelled on quantum chromodynamics (QCD), the "color" theory of the strong nuclear force, which inspired their name.

In particle physics, the W and Z bosons are vector bosons that are together known as the weak bosons or more generally as the intermediate vector bosons. These elementary particles mediate the weak interaction; the respective symbols are
W+
,
W−
, and
Z0
. The
W±
 bosons have either a positive or negative electric charge of 1 elementary charge and are each other's antiparticles. The
Z0
 boson is electrically neutral and is its own antiparticle. The three particles each have a spin of 1. The
W±
 bosons have a magnetic moment, but the
Z0
 has none. All three of these particles are very short-lived, with a half-life of about 3×10−25 s. Their experimental discovery was pivotal in establishing what is now called the Standard Model of particle physics.

<span class="mw-page-title-main">False vacuum decay</span> Hypothetical vacuum, less stable than true vacuum

In quantum field theory, a false vacuum is a hypothetical vacuum that is relatively stable, but not in the most stable state possible. This condition is known as metastable. It may last for a very long time in that state, but could eventually decay to the more stable state, an event known as false vacuum decay. The most common suggestion of how such a decay might happen in our universe is called bubble nucleation – if a small region of the universe by chance reached a more stable vacuum, this "bubble" would spread.

The Alternative models to the Standard Higgs Model are models which are considered by many particle physicists to solve some of the Higgs boson's existing problems. Two of the most currently researched models are quantum triviality, and Higgs hierarchy problem.

In the Standard Model of electroweak interactions of particle physics, the weak hypercharge is a quantum number relating the electric charge and the third component of weak isospin. It is frequently denoted and corresponds to the gauge symmetry U(1).

<span class="mw-page-title-main">Physics beyond the Standard Model</span> Theories trying to extend known physics

Physics beyond the Standard Model (BSM) refers to the theoretical developments needed to explain the deficiencies of the Standard Model, such as the inability to explain the fundamental parameters of the standard model, the strong CP problem, neutrino oscillations, matter–antimatter asymmetry, and the nature of dark matter and dark energy. Another problem lies within the mathematical framework of the Standard Model itself: the Standard Model is inconsistent with that of general relativity, and one or both theories break down under certain conditions, such as spacetime singularities like the Big Bang and black hole event horizons.

In particle physics, the Peskin–Takeuchi parameters are a set of three measurable quantities, called S, T, and U, that parameterize potential new physics contributions to electroweak radiative corrections. They are named after physicists Michael Peskin and Tatsu Takeuchi, who proposed the parameterization in 1990; proposals from two other groups came almost simultaneously.

<span class="mw-page-title-main">Higgs boson</span> Elementary particle

The Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory. In the Standard Model, the Higgs particle is a massive scalar boson with zero spin, even (positive) parity, no electric charge, and no colour charge that couples to mass. It is also very unstable, decaying into other particles almost immediately upon generation.

In particle physics, W′ and Z′ bosons refer to hypothetical gauge bosons that arise from extensions of the electroweak symmetry of the Standard Model. They are named in analogy with the Standard Model W and Z bosons.

In theoretical physics, a mass generation mechanism is a theory that describes the origin of mass from the most fundamental laws of physics. Physicists have proposed a number of models that advocate different views of the origin of mass. The problem is complicated because the primary role of mass is to mediate gravitational interaction between bodies, and no theory of gravitational interaction reconciles with the currently popular Standard Model of particle physics.

In particle physics, composite Higgs models (CHM) are speculative extensions of the Standard Model (SM) where the Higgs boson is a bound state of new strong interactions. These scenarios are models for physics beyond the SM presently tested at the Large Hadron Collider (LHC) in Geneva.
