Supersymmetric and other Novel Features and Phenomenology of QCD

Seminars

A Joint JINR Seminar will be held on 6 November 2015 in Blokhintsev conference hall BLTP. The programme of the Seminar includes a lecture of Stanley J. Brodsky (SLAC National Accelerator Laboratory, Stanford University) "Supersymmetric and other Novel Features and Phenomenology of QCD". The beginning of the lecture is set on 4.00 pm.

Abstract

I will discuss a number of novel properties of QCD, phenomena which illuminate fundamental features of hadron physics. These include effects which violate factorization theorems, flavor-dependent antishadowing, digluon-initiated reactions, collisions of flux tubes, as well as Higgs and heavy hadron production at high longitudinal momentum. I will also discuss a first approximation to nonperturbative QCD, the “Light-Front Schroedinger Equation” which incorporates color confinement and other essential spectroscopic and dynamical features of hadron physics. The resulting fermionic bound-state equations predict striking supersymmetric relations between meson and baryon spectra. I will also briefly review the "Principle of Maximum Conformality" (PMC) which systematically sets the renormalization scale order-by-order in pQCD, eliminating an unnecessary theoretical uncertainty. The PMC predictions for physical observable are independent of the choice of renormalization scheme, thus providing rigorous, precise tests of QCD and increased sensitivity to physics beyond the Standard Model.
