Central exclusive χc,bproduction at high energy colliders and gluon saturation approach
(2020) [Artigo de periódico]The central exclusive production of χcand χbat the LHC, RHIC and Tevatron energies is analyzed, using the recent unintegrated parton distribution (UGDs) functions available in the package TMDlib. Comparison with data is ... -
Evidence for top quark production in nucleus-nucleus collisions
(2020) [Artigo de periódico]Ultrarelativistic heavy ion collisions recreate in the laboratory the thermodynamical conditions prevailing in the early universe up to 10 − 6 sec , thereby allowing the study of the quark-gluon plasma (QGP), a state ... -
Investigating entanglement entropy at small x in DIS off protons and nuclei
(2020) [Artigo de periódico]In this work we analyze the entanglement entropy in deep inelastic scattering off protons and nuclei. It is computed based on the formalism where the partonic state at small-x is maximally entangled with proton being ... -
Measurements of jet multiplicity and jet transverse momentum in multijet events in proton–proton collisions at √s = 13 TeV
(2023) [Artigo de periódico]Multijet events at large transverse momentum (pT) are measured at √s = 13 TeV using data recorded with the CMS detector at the LHC, corresponding to an integrated luminosity of 36.3 fb−1. The multiplicity of jets with pT ... -
Parton saturation scaling function for exclusive production of vector mesons and deeply virtual Compton scattering
(2017) [Artigo de periódico]We provide a universal expression of cross sections for the exclusive vector meson production and deeply virtual Compton scattering (DVCS) in photon-proton and photon-nucleus interactions based on the geometric scaling ... -
Prompt photon production in high-energy pA collisions at forward rapidity
(2020) [Artigo de periódico]Prompt photon production in hadronic collisions at energies available at RHIC and at the LHC is investigated within the QCD color dipole approach. Predictions for the nuclear modification factor in pA collisions are evaluated ... -
Pseudorapidity distributions of charged particles as a function of mid- and forward rapidity multiplicities in pp collisions at √s=5.02, 7 and 13 TeV
(2021) [Artigo de periódico]The multiplicity dependence of the pseudorapidity density of charged particles in proton–proton (pp) collisions at centre-of-mass energies s√ = 5.02, 7 and 13 TeV measured by ALICE is reported. The analysis relies on track ... -
QCD evolution and skewedness effects in color dipole description of DVCS
(2004) [Artigo de periódico]We show the role played by QCD evolution and skewedness effects in the DVCS cross section at large Q2 within the color dipole description of the process at photon level. The dipole cross section is given by the saturation ...
