Dra. María Gómez Rocha

septiembre 22 @ 12:00 am - 1:30 pm

Lugar: Seminario de Física Teórica I, 3ª planta Oeste
Día: Viernes 22 de Septiembre   (atención al día inusual)
Hora: 12h
Título: Effective-particle approach to bound states of quarks and gluons in heavy-flavor QCD
Resumen:
In response to the growing need for theoretical tools that can be used in QCD to describe and understand the dynamics of gluons in hadrons in the Minkowski space-time, the renormalization group procedure for effective particles (RGPEP) is shown in the simplest available context of heavy quarkonia to exhibit a welcome degree of universality in its first approximation, once one assumes that beyond perturbation theory gluons obtain effective mass. Namely, in the second-order terms, the Coulomb potential with Breit-Fermi spin couplings in the effective quark-antiquark component of a heavy quarkonium, is corrected in one-flavor QCD by a spin-independent harmonic oscillator term that does not depend on the assumed effective gluon mass or the choice of the RGPEP generator.
