Olga Evdokimov is a Russian born professor of physics at the University of Illinois, Chicago (UIC). [1] She is a High Energy Nuclear Physicist, who currently collaborates on two international experiments; the Solenoidal Tracker At RHIC (STAR) experiment at the Relativistic Heavy Ion Collider (RHIC), Brookhaven National Laboratory, Upton, New York and the Compact Muon Solenoid (CMS) experiment at the LHC (Large Hadron Collider), CERN, Geneva, Switzerland.
Evdokimov obtained both her MS in theoretical physics in 1996 and her Ph.D. in Physical & Mathematical Sciences in 1999 from the Ivanovo State University, Ivanovo, Russia. She performed her Ph.D. research at Laboratory for High Energy Physics at Joint Institute for Nuclear Research, Dubna, Russia. Her thesis was titled "Alignment and Fast Algorithms of Data Treatment for 4π-geometry Detectors."
Evdokimov worked first as a post-doctoral researcher at Purdue University. In 2005 she joined UIC as an Adjunct Assistant Professor, in 2006 she became an Assistant Professor. She was promoted to Associate Professor in 2010 before becoming Full Professor in 2015. [1] In 2013 she received a Teaching Recognition Award from UIC's Council for Excellence in Teaching and Learning (CETL). [2]
Evdokimov has served on a number of key management positions of the STAR collaboration. She was STAR's Spectra Physics Working Group Convener for 4 years. From 2008 - 2011 she served as one of the Deputy Spokespeople. In August 2016 she was elected as the Chair of the Institutional Council of the STAR collaboration, she was reelected in 2018 for a second two year term. In CMS she has been on the Heavy-Ion Publication Committee.
Evdokimov is an active member of the physics community. She has served as an elected member of the RHIC/AGS Users' Executive Committee (2013-2016), [3] [4] on the Executive Committee for the NERSC (National Energy Research Scientific Computing Center) Users Group, [5] and in 2018 she was appointed to the U.S. DOE/NSF Nuclear Science Advisory Committee (NSAC). [6] [7] NSAC provides advice on the nations program for basic nuclear science research. DoE and NSF share the responsibility for selecting NSAC's members.
In 2017 she co-chaired the international conference on ultra-relativistic heavy-ion collisions (Quark Matter 2017) conference which took place from February 5–11 in Chicago [8] and was co-editor of Volume 967 of Nuclear Physics A which reported on the results presented at this conference. [9]
Evdokimov's research focuses on understanding the properties and evolution of QCD matter under the extreme temperatures and energy densities achieved in ultra-relativistic heavy ion collisions. The form of matter created in such collisions is termed the quark gluon plasma (QGP). She is an experimental nuclear physicist and a member of two large international collaborations: the STAR experiment at the Relativistic Heavy Ion Collider (RHIC) and the CMS experiment at the Large Hadron Collider (LHC).
Evdokimov is co-author of over 1000 journal publications and has an h-index of 157. [10] Her specific research has contributed to the understanding of bulk identified particle production in the QGP, [11] [12] and their subsequent collective motion, [13] the baryon enhancement puzzle, and studies of jet production and jet-medium interactions, [14] [15] [16] and techniques for probing jet quenching via multi-particle correlations. [17] [18]
She is a co-convener of one of the four physics working groups leading the effort to organize the physics studies and detector design concepts in preparation for the realization of the Electron Ion Collider (EIC). [19]
The Relativistic Heavy Ion Collider is the first and one of only two operating heavy-ion colliders, and the only spin-polarized proton collider ever built. Located at Brookhaven National Laboratory (BNL) in Upton, New York, and used by an international team of researchers, it is the only operating particle collider in the US. By using RHIC to collide ions traveling at relativistic speeds, physicists study the primordial form of matter that existed in the universe shortly after the Big Bang. By colliding spin-polarized protons, the spin structure of the proton is explored.
High-energy nuclear physics studies the behavior of nuclear matter in energy regimes typical of high-energy physics. The primary focus of this field is the study of heavy-ion collisions, as compared to lighter atoms in other particle accelerators. At sufficient collision energies, these types of collisions are theorized to produce the quark–gluon plasma. In peripheral nuclear collisions at high energies one expects to obtain information on the electromagnetic production of leptons and mesons that are not accessible in electron–positron colliders due to their much smaller luminosities.
Hadronization is the process of the formation of hadrons out of quarks and gluons. There are two main branches of hadronization: quark-gluon plasma (QGP) transformation and colour string decay into hadrons. The transformation of quark-gluon plasma into hadrons is studied in lattice QCD numerical simulations, which are explored in relativistic heavy-ion experiments. Quark-gluon plasma hadronization occurred shortly after the Big Bang when the quark–gluon plasma cooled down to the Hagedorn temperature when free quarks and gluons cannot exist. In string breaking new hadrons are forming out of quarks, antiquarks and sometimes gluons, spontaneously created from the vacuum.

In high-energy physics, jet quenching is a phenomenon that can occur in the collision of ultra-high-energy particles. In general, the collision of high-energy particles can produce jets of elementary particles that emerge from these collisions. Collisions of ultra-relativistic heavy-ion particle beams create a hot and dense medium comparable to the conditions in the early universe, and then these jets interact strongly with the medium, leading to a marked reduction of their energy. This energy reduction is called "jet quenching".
Quark–gluon plasma is an interacting localized assembly of quarks and gluons at thermal and chemical (abundance) equilibrium. The word plasma signals that free color charges are allowed. In a 1987 summary, Léon van Hove pointed out the equivalence of the three terms: quark gluon plasma, quark matter and a new state of matter. Since the temperature is above the Hagedorn temperature—and thus above the scale of light u,d-quark mass—the pressure exhibits the relativistic Stefan-Boltzmann format governed by temperature to the fourth power and many practically massless quark and gluon constituents. It can be said that QGP emerges to be the new phase of strongly interacting matter which manifests its physical properties in terms of nearly free dynamics of practically massless gluons and quarks. Both quarks and gluons must be present in conditions near chemical (yield) equilibrium with their colour charge open for a new state of matter to be referred to as QGP.
A strangelet is a hypothetical particle consisting of a bound state of roughly equal numbers of up, down, and strange quarks. An equivalent description is that a strangelet is a small fragment of strange matter, small enough to be considered a particle. The size of an object composed of strange matter could, theoretically, range from a few femtometers across to arbitrarily large. Once the size becomes macroscopic, such an object is usually called a strange star. The term "strangelet" originates with Edward Farhi and Robert Jaffe in 1984. Strangelets can convert matter to strange matter on contact. Strangelets have been suggested as a dark matter candidate.
In high-energy nuclear physics, strangeness production in relativistic heavy-ion collisions is a signature and diagnostic tool of quark–gluon plasma (QGP) formation and properties. Unlike up and down quarks, from which everyday matter is made, heavier quark flavors such as strange and charm typically approach chemical equilibrium in a dynamic evolution process. QGP is an interacting localized assembly of quarks and gluons at thermal (kinetic) and not necessarily chemical (abundance) equilibrium. The word plasma signals that color charged particles are able to move in the volume occupied by the plasma. The abundance of strange quarks is formed in pair-production processes in collisions between constituents of the plasma, creating the chemical abundance equilibrium. The dominant mechanism of production involves gluons only present when matter has become a quark–gluon plasma. When quark–gluon plasma disassembles into hadrons in a breakup process, the high availability of strange antiquarks helps to produce antimatter containing multiple strange quarks, which is otherwise rarely made. Similar considerations are at present made for the heavier charm flavor, which is made at the beginning of the collision process in the first interactions and is only abundant in the high-energy environments of CERN's Large Hadron Collider.
Relativistic heavy-ion collisions produce very large numbers of subatomic particles in all directions. In such collisions, flow refers to how energy, momentum, and number of these particles varies with direction, and elliptic flow is a measure of how the flow is not uniform in all directions when viewed along the beam-line. Elliptic flow is strong evidence for the existence of quark–gluon plasma, and has been described as one of the most important observations measured at the Relativistic Heavy Ion Collider (RHIC).

STARlight is a computer simulation event generator program to simulate ultra-peripheral collisions among relativistic nuclei. It simulates both photonuclear and two-photon interactions. It can simulate multiple interactions among a single ion pair, such as vector meson photoproduction accompanied by mutual Coulomb excitation.
An electron–ion collider (EIC) is a type of particle accelerator collider designed to collide spin-polarized beams of electrons and ions, in order to study the properties of nuclear matter in detail via deep inelastic scattering. In 2012, a whitepaper was published, proposing the developing and building of an EIC accelerator, and in 2015, the Department of Energy Nuclear Science Advisory Committee (NSAC) named the construction of an electron–ion collider one of the top priorities for the near future in nuclear physics in the United States.
