He is an originator of
Parke–Taylor amplitudes, which he developed with his colleague,
Tomasz Taylor. Parke-Taylor amplitudes represent a new approach to computing scattering amplitudes in
quantum chromodynamics using symmetry methods such as
supersymmetry. This work was further extended in collaboration with Michelangelo Mangano and Xu Zhan. The discovery of the Parke-Taylor amplitudes ignited the amplitude revolution: a major advance in our understanding and calculability of scattering amplitudes in
gauge theories, the foundation of
particle physics. This advance is discussed in detail in Chapter 11 of
Graham Farmelo's book "The Universe speaks in Numbers". Parke's important Amplitude papers are linked here. With collaborator Gregory Mahon and others he pioneered the study of spin correlations in
Top Quark pair production at Hadron collider which has led to the confirmation of
quantum entanglement at the highest possible energy by
ATLAS and
CMS. Here is a link to his important Top Quark papers. Parke is also an expert on
neutrino physics. He gave the first analytical solution to the
MSW effect including the non-adabatic region and has made important contributions to the physics of Long baseline Neutrino Oscillation experiments,
T2K,
NOvA,
Hyper-Kamiokande and
DUNE as well as the reactor experiments
RENO,
Daya Bay and
JUNO. Here is a link to his important Neutrino papers. He has also written papers on Magnetic Monopoles and the decay of the false vacuum in curved space time. ==Personal life==
