Title: Interplay of soft and perturbative correlations in multiparton interactions at central rapidities

Abstract

We study the role of soft/nonperturbative correlations in the multi parton interactions in the central kinematics relevant for double parton scattering (DPS) and underlying event (UE) measurements at ATLAS and CMS. We show that the effect of soft correlations is negligible for DPS regime (typical transverse momenta larger than 10–20 GeV), but may be important for UE (several GeV scale). The characteristic scale where soft correlations become important increases with decrease of x (energy increase) leading to approximately constant σ eff at small x.

Revealing minijet dynamics via centrality dependence of double parton interactions in proton–nucleus collisions

Journal Article Alvioli, Massimiliano ; Azarkin, Maxim ; Blok, Boris ; ... - European Physical Journal. C, Particles and Fields

One of the main challenges hampering an accurate measurement of the double parton scattering (DPS) cross sections is the difficulty in separating the DPS from the leading twist (LT) contributions. We argue that such a separation can be achieved, and cross section of DPS measured, in proton–nucleus scattering by exploiting the different centrality dependence of DPS and LT processes. We developed a Monte Carlo implementation of the DPS processes which includes realistic nucleon–nucleon (NN) correlations in nuclei, an accurate description of transverse geometry of both hard and soft NN collisions as well as fluctuations of the strength of interaction ofmore »« less

Probing superfast quarks in nuclei through dijet production at the LHC

Journal Article Freese, Adam J. ; Sargsian, Misak M. ; Strikman, Mark I. - European Physical Journal. C, Particles and Fields

We investigate dijet production from proton-nucleus collisions at the Large Hadron Collider (LHC) as a means for observing superfast quarks in nuclei with Bjorken x>1 . Kinematically, superfast quarks can be identified through directly measurable jet kinematics. Dynamically, their description requires understanding several elusive properties of nuclear QCD, such as nuclear forces at very short distances, as well as medium modification of parton distributions in nuclei. In the present work, we develop a model for nuclear parton distributions at large x in which the nuclear dynamics at short distance scales are described by two- and three-nucleon short range correlations (SRCs).more »« less

Nonperturbative-transverse-momentum effects and evolution in dihadron and direct photon-hadron angular correlations in $p + p$ collisions at $\sqrt{s} = 510 GeV$

Journal Article Adare, A. ; Aidala, C. ; Ajitanand, N. N. ; ... - Physical Review. D.

Dihadron and isolated direct photon-hadron angular correlations are measured in p þ ffiffiffi p collisions at s p ¼ 510 GeV. Correlations of charged hadrons of 0.7 < pT < 10 GeV=c with π0 mesons of 4 < pT < 15 GeV=c or isolated direct photons of 7 < pT < 15 GeV=c are used to study nonperturbative effects generated by initial-state partonic transverse momentum and final-state transverse momentum from fragmentation. The nonperturbative behavior is characterized by measuring the out-of-plane transverse momentum component pout perpendicular to the axis of the trigger particle, which is the high-pT direct photon or π0.more »« less
