Goshaw and Liu Measure Rare Process at CERN

Prof. Al Goshaw's and his research group member and graduate student Mia Liu have recently made a measurement of one of the rarest processes observed in experiments at the CERN Large Hadron Collider. They have observed the production of three electroweak bosons by using the full LHC Run 1 data set of proton-proton collisions at a center of mass energy of 8 TeV. The final state consists of a W boson plus two high energy photons. This provides a test of the Standard Model's prediction for the quartic point-like coupling WWgg. The results will be highlighted in an article in the CERN Courier magazine and are being submitted to Physical Review Letters for publication. Read it online here. The Duke research was carried out as part of Liu's PhD Thesis. Dr. Liu has recently accepted a position at Fermilab where she will continue research at the CERN LHC with the CMS Collaboration.
