Gauge-invariant Mass Terms and Wave Functions

open access: yes, 2012
We outline a method of relating the quantum effective action and the ground state wave function of a field theory. This method, along with a gauge-invariant mass term and the previously obtained vacuum wave function, is used to arrive at the leading ...

Transverse momentum spectrum of dilepton pair in the unpolarized π− N Drell-Yan process within TMD factorization

open access: yesJournal of High Energy Physics, 2017
We study the transverse momentum spectrum of dilepton produced in the unpolarized π− N Drell-Yan process, using transverse momentum dependent factorization up to next-to-logarithmic order of QCD. We extract the nonperturbative Sudakov form factor for the

Parton saturation at strong coupling from AdS/CFT

open access: yes, 2010
I describe the parton picture at strong coupling emerging from the gauge/gravity duality, with emphasis on the universality of the phenomenon of parton saturation. I discuss several consequences of this picture for the phenomenology of a strongly coupled

QCD Phenomenology and Heavy Ion Physics

open access: yesJournal of Physics: Conference Series, 2006
We describe application of saturation/Color Glass Condensate physics to heavy ion collisions, concentrating on several important observables. We show how simple saturationinspired assumptions about particle production in heavy ion collisions allow one to accurately describe total charged particle multiplicity as a function of the collision's centrality,
