DOI: 10.1007/jhep06(2021)171
Abstract: Abstract The all-loop resummation of SU(N) gauge theory amplitudes is known to factorize into an IR-divergent (soft and collinear) factor and a finite (hard) piece. The divergent factor is universal, whereas the hard function is… read more here.

Abstract: A bstractIt is shown that odd harmonic azimuthal correlations, including the directed flow v1, in forward two-particle production in peripheral proton-nucleus (pA) collisions can arise simply from the radial nuclear profile of a large nucleus.… read more here.

DOI: 10.1103/physrevd.100.014008
Abstract: We consider the quarkonium diffusion, dissociation and recombination inside a quark-gluon plasma. We compute scattering amplitudes in potential nonrelativistic QCD for relevant processes. These processes include the gluon absorption/emission at the order $gr$, inelastic scattering… read more here.

Abstract: We study the small-x evolution equation for the gluon generalized parton distribution E_{g} of the nucleon. It is shown that E_{g} at vanishing skewness exhibits the Regge behavior identical to the Balitsky-Fadin-Kuraev-Lipatov pomeron despite its… read more here.
