Cox has conducted research on the fundamental particles such as fermions, quarks, leptons and bosons that constitute matter. He has been involved in numerous experiments at Brookhaven National Laboratory, Stanford Linear Accelerator Center, Fermilab and CERN. Cox's research contributing to the discovery of the Higgs particle was named as one of the 12 most significant research achievements at the University of Virginia of the last 50 years.[2]

Cox is a fellow of American Physical Society,[3] American Association for the Advancement of Science,[4] and American Association of University Professors. He has served as a chair of the Southeastern American Physical Society and as chair of the American Physical Society Publications Committee.[5]

Education

Cox was a James B. Duke Fellow and received his Doctoral degree from Duke University in 1967. He then worked at Johns Hopkins University as a Research Associate from 1967 till 1969.[1]

Career

Cox taught at Johns Hopkins University an Assistant Professor till 1973. He went to Fermilab on leave from Johns Hopkins in 1972 to serve as spokesperson of Experiment E95.[6] He joined the Lab in 1973 where he held numerous scientific and administrative appointments. He was promoted to Deputy Head in 1975, and to then Head of Proton Laboratory in the following year. Following his time as Proton Lab head, Cox served as a Group Leader of Low Current Superconducting Magnet Group in the late 1970s and was then appointed as Head of Research Services Department in 1981. He served as Deputy Chairman of Fermilab Physics Department from 1983 till 1984.[1]

In 1988, Cox made a proposal for an experiment at the Super Conducting Super Collider (SSC) in Texas and left Fermilab to take a position as a Professor of Physics at University of Virginia where he founded the High Energy Physics Group at the University.[7]

Research

At Duke, Johns Hopkins, Fermilab and the University of Virginia, Cox participated in a number of high-energy physics experiments on fundamental particles of nature such as fermions, quarks, leptons and bosons that constitute the atoms. In his early career, he was involved in experiments revolving around strong and electromagnetic interactions. One of Cox's experiment measured the charge asymmetry of the ɳ->π+π -π 0 decay in a search for C violation.[8]

Research at Fermilab

After joining Fermilab, Cox served as scientific spokesman for a series of high-energy experiments that studied the interactions of quarks and gluons by measuring the production of direct photons and lepton pairs. One of the experiments involved observation of direct photon production by hadrons during the 1970s. His work led to one of the first two observations of direct photon production from quark-quark interactions in hadronic collisions.[9]

In the early 1980s, Cox served as spokesperson for the Fermilab Experiment E537, which measured the production of high mass muon pairs by antiprotons and confirmed that deep inelastic structure functions as measured in lepton scattering were the same as the structure functions that were appropriate to describe lepton pair production.[10] After E537, Cox served as spokesperson for the E705 experiment focused on studying the production of direct photons and charmonium states by antiproton, proton and π± beams.[11]

Research at CERN and University of Virginia

In the late 1980s, after taking a position as professor to the University of Virginia, Cox initiated a design effort for a detector that would measure the CP violating effects in the B meson system at the Superconducting supercollider (SSC) in Texas. After the demise of the SSC, he then turned his efforts to CERN and the design of the LHCb heavy flavor experiment at the LHC.[12]

In addition to his work at CERN, Cox's research following his appointment at University of Virginia also focused on CP violation in the neutral kaon system. He led the UVa effort on the KTeV experiment, which indicated the first statistically significant observation of “direct” CP violation by the measurement of a non-zero Re(ɳ’/ɳ).[13] proving that the CP violation (time reversal violation) is an intrinsic property of the weak interaction. KTeV group at University of Virginia also made significant contributions to the discovery of a large CP violation effect in KLɳ π +π - e + e - .[14]

Cox's later work has involved the search for Supersymmetry at the CMS experiment at the LHC.[15]
