Saturation effects in SIDIS at very forward rapidities

E. Iancu, A. H. Mueller, D. N. Triantafyllopoulos +1

Using the dipole picture for electron-nucleus deep inelastic scattering at small Bjorken , we study the effects of gluon saturation in the nuclear target on the cross-section fo…

Cosmic antihelium-3 nuclei sensitivity of the GAPS experiment

N. Saffold, T. Aramaki, R. Bird +52

The General Antiparticle Spectrometer (GAPS) is an Antarctic balloon experiment designed for low-energy (0.10.3 GeV/) cosmic antinuclei as signatures of dark matter annihilat…

Nuclear scattering configurations of onia in different frames

Anh Dung Le, Alfred H. Mueller, Stéphane Munier

In the scattering of a small onium off a large nucleus at high center-of-mass energies, when the parameters are set in such a way that the cross section at fixed impact parameter i…

Neural-network analysis of Parton Distribution Functions from Ioffe-time pseudodistributions

Luigi Del Debbio, Tommaso Giani, Joseph Karpie +3

We extract two nonsinglet nucleon Parton Distribution Functions from lattice QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis within the NNPDF framewor…

Nuclear modification factors for jet fragmentation

P. Caucal, E. Iancu, A. H. Mueller +1

Using a recently-developed perturbative-QCD approach for jet evolution in a dense quark-gluon plasma, we study the nuclear modification factor for the jet fragmentation function. T…

Predictive power of transverse-momentum-dependent distributions

Manvir Grewal, Zhong-Bo Kang, Jian-Wei Qiu +1

We investigate the predictive power of transverse-momentum-dependent (TMD) distributions as a function of the light-cone momentum fraction and the hard scale defined by the…

Lepton Pair Production Through Two Photon Process in Heavy Ion Collisions

Spencer Klein, Al Mueller, Bo-Wen Xiao +1

This paper investigates the electromagnetic production of lepton pairs with low transverse momentum in relativistic heavy ion collisions. We estimate the initial photons' transvers…

Collinear resummations for the non-linear evolution in QCD at high energy

B. Ducloué, E. Iancu, A. H. Mueller +2

When computed to next-to-leading order in perturbative QCD, the non-linear Balitsky-Kovchegov (BK) equation for the high-energy evolution of the dipole-hadron scattering appears to…
