Latifa Elouadrhiri is a Moroccan experimental physicist and researcher at Thomas Jefferson National Accelerator Facility studying elementary particle physics and nuclear physics. She has worked significantly with the CLAS collaboration in Jefferson Lab's Hall B, performing 3D imaging of nucleons. Additionally, she is the spokesperson of the Deeply Virtual Compton Scattering (DVCS) experiment, studying Generalized Parton Distributions [1] . [2]

Elouadrhiri is a fellow of the American Physical Society, and has served as a member of the Department of Energy (DOE) Nuclear Science Advisory Committee (NSAC) and the DOE Nuclear Physics (NP) Committee of Visitors (COV). [1]

Childhood

Latifa Elouadrhiri’s was born in Morocco she was one of eight children. She was born to a mother who had never been to school and couldn't read or write but who supported them and "believed in the power of education." Elouadrhiri became fascinated with physics when she first took a physics class in high school. When she turned 15 she got her first physics book from a flea market. [3]

Education

Elouadrhiri obtained a physics B.Sc. from Mohammed V University in 1984, continuing to complete a M.Sc. in theoretical physics in 1987 entitled Poincare and Lorentz group (Group Theory). She continued to complete a Diplôme des Etudes Approfondies at the University of Blaise Pascal, Clermont-Ferrand in particle physics in 1987 entitled Development of Drift Chamber tracking Program. Following this, she completed her PhD in 1991 in physics, also at the University of Blaise Pascal, Clermont-Ferrand in experimental hadronic physics with electromagnetic probes, producing a thesis entitled Measurement of the Nucleon Axial Form Factor from Low Energy Pion Electroproduction (Saclay nuclear physics experiment) [4]

Career

At an American Physical Society meeting her work got the attention of Nathan Isgur who at the time was the chief scientist and Jefferson Lab. [3] In 1994, Elouadrhiri chose to come to Jefferson Laboratory for a joint appointment with CNU, joining the lab as a staff scientist in 2001 as one of the first female staff scientists in the physics division. Here, she led the measurement of the first observation of electron beam asymmetries in polarized, exclusive Deeply Virtual Compton Scattering. From 2006 to 2015, Elouadrhiri was the Project Manager for the Hall B 12 GeV Upgrade, including all detectors, magnets and infrastructure for the CLAS12 system. [1]

Other

In 2015, Elouadrhiri was interviewed for an article in the Chicago Tribune about the impacts of women in science and engineering. [5]

In 2018, she was personally recognized by the US Embassy in Rabat for her contributions to nuclear physics on both the official embassy Twitter [6] and Facebook [7] pages.

GlueX is a particle physics experiment located at the Thomas Jefferson National Accelerator Facility (JLab) accelerator in Newport News, Virginia. Its primary purpose is to better understand the nature of confinement in quantum chromodynamics (QCD) by identifying a spectrum of hybrid and exotic mesons generated by the excitation of the gluonic field binding the quarks. Such mesonic states are predicted to exist outside of the well-established quark model, but none have been definitively identified by previous experiments. A broad high-statistics survey of known light mesons up to and including the is also underway.

In 2011 it was renamed to its current name A.I. Alikhanyan National Science Laboratory.

Nucleon spin structure describes the partonic structure of nucleon intrinsic angular momentum (spin). The key question is how the nucleon's spin, whose magnitude is 1/2ħ, is carried by its constituent partons. It was originally expected before the 1980s that quarks carry all of the nucleon spin, but later experiments contradict this expectation. In the late 1980s, the European Muon Collaboration (EMC) conducted experiments that suggested the spin carried by quarks is not sufficient to account for the total spin of the nucleons. This finding astonished particle physicists at that time, and the problem of where the missing spin lies is sometimes referred to as the proton spin crisis.

CEBAF Large Acceptance Spectrometer (CLAS) is a nuclear and particle physics detector located in the experimental Hall B at Jefferson Laboratory in Newport News, Virginia, United States. It is used to study the properties of the nuclear matter by the collaboration of over 200 physicists from many countries all around the world.

The EMC effect is the surprising observation that the cross section for deep inelastic scattering from an atomic nucleus is different from that of the same number of free protons and neutrons. From this observation, it can be inferred that the quark momentum distributions in nucleons bound inside nuclei are different from those of free nucleons. This effect was first observed in 1983 at CERN by the European Muon Collaboration, hence the name "EMC effect". It was unexpected, since the average binding energy of protons and neutrons inside nuclei is insignificant when compared to the energy transferred in deep inelastic scattering reactions that probe quark distributions. While over 1000 scientific papers have been written on the topic and numerous hypotheses have been proposed, no definitive explanation for the cause of the effect has been confirmed. Determining the origin of the EMC effect is one of the major unsolved problems in the field of nuclear physics.
