Charm, bottom, and quarkonia cross sections for double and triple-parton scatterings in high-energy proton-nucleus and nucleus-nucleus collisions / d'Enterria, David (CERN) ; Snigirev, Alexander M (SINP, Moscow ; Moscow State U. ; Dubna, JINR)
The framework to compute the cross sections for the productionof particles with high mass and/or large transverse momentum in double-(DPS), triple- (TPS), and in general n-parton scatterings from thecorresponding single-parton ($\sigma_{\rm SPS} $) values in high-energy proton and nuclear collisions is reviewed. The basic parameter of the factorized n-parton scatteringansatz is an effective cross section $\sigma_{\rm eff}$ encoding all unknowns about theunderlying generalized n-parton distribution in the proton (nucleon).

Triple parton scatterings in high-energy proton-proton collisions / d'Enterria, David (CERN) ; Snigirev, Alexander M. (SINP, Moscow ; Moscow State U.)
A generic expression to compute triple parton scattering (TPS) cross sections in high-energy proton-proton (pp) collisions is presented as a function of the corresponding single-parton cross sections and the transverse parton distribution in the proton encoded in an effective parameter $\sigma_{\rm eff,TPS}$. The value of $\sigma_{\rm eff,TPS}$ is closely related to the similar effective cross section that characterizes double-parton scatterings, and amounts to $\sigma_{\rm eff,TPS} = 12.5 \pm 4.5$ mb.

Triple parton scatterings in proton-nucleus collisions at high energies / d'Enterria, David (CERN) ; Snigirev, Alexander M. (SINP, Moscow ; Moscow State U.)
A generic expression to compute triple parton scattering (TPS) cross sections in high-energy proton-nucleus (pA) collisions is derived as a function of the corresponding single-parton cross sections and an effective parameter encoding the transverse parton profile of the proton. The TPS cross sections are enhanced by a factor of $9\,A\approx 2000$ in pPb compared to those in proton-nucleon collisions at the same center-of-mass energy. [...]

Pair production of quarkonia and electroweak bosons from double-parton scatterings in nuclear collisions at the LHC / d'Enterria, David (CERN) ; Snigirev, Alexander M. (SINP, Moscow)
Cross sections for the concurrent production of pairs of quarkonia (J/psi, Upsilon) and/or gauge bosons (W, Z) from double-parton scatterings (DPS) in high-energy proton-nucleus and nucleus-nucleus collisions at the LHC are calculated. The estimates are based on next-to-leading-order perturbative QCD predictions, including nuclear modifications of the parton densities, for the corresponding single-scattering cross sections. [...]

Double-parton scattering cross sections in proton-nucleus and nucleus-nucleus collisions at the LHC / d'Enterria, David (CERN) ; Snigirev, Alexander M. (Moscow State U.)
Simple generic expressions to compute double-parton scattering (DPS) cross sections in high-energy proton-nucleus and nucleus-nucleus collisions, as a function of the corresponding single-parton cross sections, are presented. Estimates of DPS contributions are studied for two specific processes at LHC energies: (i) same-sign W-boson pair production in p-Pb, and (ii) double-J/psi production in Pb-Pb, using NLO predictions with nuclear parton densities for the corresponding single-parton cross sections. [...]

Enhanced J/Psi production from double parton scatterings in nucleus-nucleus collisions at the Large Hadron Collider / d'Enterria, David (CERN) ; Snigirev, Alexander M. (SINP, Moscow)
A generic expression of double-parton scattering (DPS) cross sections in high-energy nucleus-nucleus collisions is derived as a function of the corresponding single-parton hard cross sections. We consider the case of prompt-J/psi production and find that the DPS contributions represent (15--20)% of the total J/psi cross section in lead-lead (PbPb) collisions at the CERN Large Hadron Collider.

Same-sign WW production in proton-nucleus collisions at the LHC as a signal for double parton scattering / d'Enterria, David (CERN) ; Snigirev, Alexander M. (SINP, Moscow)
The production of same-sign W-boson pairs from double parton scatterings (DPS) in proton-lead (p-Pb) collisions at the CERN Large Hadron Collider is studied. The signal and background cross sections are estimated with next-to-leading-order perturbative QCD calculations using nuclear parton distribution functions for the Pb ion. [...]
