Graham Garland RossFRS (1944 – 31 October 2021) was a Scottishtheoretical physicist who was the Emeritus Professor ofPhysics at theUniversity of Oxford and Emeritus Fellow ofWadham College.^[2][3][4][5]

Ross was known for constructing models offundamental interactions and verifying them by experimentation. With others, while at theEuropean Organization for Nuclear Research (CERN) inGeneva,^[6] he predicted thatgluon radiation would generatecollimatedjets of particles inelectron–positron annihilation, which subsequently established the existence of the gluon. He made contributions to the foundation of theperturbative treatment ofquantum chromodynamics, applying it to high-energy processes and developing connections with the low-energyquark model. He developed predictions of unified models of the fundamental forces for polarisedleptonscattering, for sin²θ_W, forproton decay, and forinflationary cosmology. He discovered that insupersymmetric models, theelectroweak symmetry can be broken by quantum effects, and he was among the first researchers to develop models based on this idea.^[7]

Ross died suddenly on 31 October 2021.^[4]

Ross was elected aFellow of the Royal Society (FRS) in 1991.^[8] In 2012, he was given theDirac Medal by theInstitute of Physicsfor his theoretical work in developing both the Standard Model of fundamental particles and forces and theories beyond the Standard Model that have led to many new insights into the origins and nature of the universe.^[9]
