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

Abstract

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 of nucleon with nucleus (color fluctuation effects). Our method allows the calculation of probability distributions of single and double dijet events as a function of centrality, also distinguishing double hard scatterings originating from a single target nucleon and from two different nucleons. We present numerical results for the rate of DPS as a function of centrality, following the model developed by the ATLAS collaboration which relates the distribution over the number of wounded nucleons to the distribution over the sum of transverse energies of hadrons produced at large negative (along the nucleus direction) rapidities, which is experimentally measurable. We suggest amore »« less

Intrinsic transverse momentum and parton correlations from dynamical chiral symmetry breaking

Journal Article Peter Schweitzer, Mark Strikman, Christian Weiss - Journal of High Energy Physics

The dynamical breaking of chiral symmetry in QCD is caused by nonperturbative interactions on a distance scale rho ~ 0.3 fm, much smaller than the typical hadronic size R ~ 1 fm. These short-distance interactions influence the intrinsic transverse momentum distributions of partons and their correlations at a low normalization point. We study this phenomenon in an effective description of the low-energy dynamics in terms of chiral constituent quark degrees of freedom, which refers to the large-N_c limit of QCD. The nucleon is obtained as a system of constituent quarks and antiquarks moving in a self-consistent classical chiral field (relativisticmore »« less

D0 results on diphoton direct production and double parton interactions in photon + 3 jet events

Conference Sawyer, Lee ; /Louisiana Tech. U. - PoS DIS2010:134,2010

We report the measurement of differential diphoton direct production cross sections and a study of photon + 3-jet events with double parton (DP) interactions, based on data taken with the D0 experiment at the Fermilab Tevatron proton-antiproton collider. We measure single differential cross sections as a function of the diphoton mass, the transverse momentum of the diphoton system, the azimuthal angle between the photons, and the polar scattering angle of the photons. In addition, we measure double differential cross sections considering the last three kinematic variables in three diphoton mass bins. The results are compared with different perturbative QCD predictionsmore »« less

Minijet deformation and charge-independent angular correlations on momentum subspace ({eta},{phi}) in Au-Au collisions at {radical}(s{sub NN})=130 GeV

Journal Article Adams, J ; Barnby, L S ; Blyth, C O ; ... - Physical Review. C, Nuclear Physics

Measurements of two-particle correlations on angular difference variables {eta}{sub 1}-{eta}{sub 2} (pseudorapidity) and {phi}{sub 1}-{phi}{sub 2} (azimuth) are presented for all primary charged hadrons with transverse momentum 0.15{<=}p{sub t}{<=}2 GeV/c and |{eta}|{<=}1.3 from Au-Au collisions at {radical}(s{sub NN})=130 GeV. Large-amplitude correlations are observed over a broad range in relative angles where distinct structures appear on the same-side and away-side (i.e., relative azimuth less than {pi}/2 or greater than {pi}/2). The principal correlation structures include that associated with elliptic flow plus a strong, same-side peak. It is hypothesized that the latter results from correlated hadrons associated with semi-hard parton scattering inmore »« less

Transverse parton structure of the nucleon and the black-disk limit in high-energy scattering

Conference Frankfurt, L ; Strikman, M ; Weiss, C

The transverse spatial distribution of partons in the nucleon (generalized parton distributions) is a crucial ingredient in the description of high-energy ep and pp scattering with hard QCD processes. Experimental information about the transverse spatial distribution of gluons comes from measurements of the t-dependence of J/psi production at HERA and other processes. We discuss the physical mechanisms leading to a growth of the nucleon's transverse size at small x. Based on this information, we study the interaction of small-size color dipoles with the proton in the leading log Q{sup 2} approximation. We find that at small x and central impactmore »« less

We present the first large-acceptance measurement of event-wise mean transverse momentum <p{sub t}> fluctuations for Au-Au collisions at nucleon-nucleon center-of-momentum collision energy {radical}(s{sub NN}) = 130 GeV. The observed nonstatistical <p{sub t}> fluctuations substantially exceed in magnitude fluctuations expected from the finite number of particles produced in a typical collision. The r.m.s. fractional width excess of the event-wise <p{sub t}> distribution is 13.7{+-}0.1(stat) {+-}1.3(syst)% relative to a statistical reference, for the 15% most-central collisions and for charged hadrons within pseudorapidity range vertical bar {eta} vertical bar <1,2{pi} azimuth, and 0.15{<=}p{sub t} {<=} 2 GeV/c.
