John Clayton Taylor

Education Taylor earned his PhD degree from the University of Cambridge in 1956, under the supervision of Richard J. Eden and Abdus Salam. His thesis was titled Renormalisation and Related Topics in Quantum Field Theory.

Research Taylor has made contributions to quantum field theory and the physics of elementary particles. His contributions include the discovery (also made independently by Lev Landau) of singularities in the analytical structure of the Feynman integrals for processes in quantum field theory, the PCAC nature of radioactive decay of the pion and the discovery in 1971 of the so-called Slavnov–Taylor identities, which control symmetry and renormalisation of gauge theories.

With various collaborators, in 1980 he discovered that real and virtual infrared divergences do not cancel in QCD as they do in QED. They also showed how these infrared divergences exponentiate. In addition, they contributed to the resummation programme in thermal QCD, simplifying the "hard" part of the effective action. Later, they studied complications arising from the non-polynomial nature of the QCD Hamiltonian in the (unitary) Coulomb gauge. His certificate of election reads:
