Title: Energy dependence of the ridge in high multiplicity proton-proton collisions

Abstract

In this study, we demonstrate that the recent measurement of azimuthally collimated, long-range rapidity (“ridge”) correlations in √s=13 TeV proton-proton (p+p) collisions by the ATLAS Collaboration at the LHC are in agreement with expectations from the color glass condensate effective theory of high-energy QCD. The observation that the integrated near-side yield as a function of multiplicity is independent of collision energy is a natural consequence of the fact that multiparticle production is driven by a single semihard saturation scale in the color glass condensate framework. We argue further that the azimuthal structure of these recent ATLAS ridge measurements strongly constrains hydrodynamic interpretations of such correlations in high-multiplicity p+p collisions.

Mass Ordering of Spectra from Fragmentation of Saturated Gluon States in High-Multiplicity Proton-Proton Collisions

Journal Article Schenke, Björn; Schlichting, Sören; Tribedy, Prithwish; ... - Physical Review Letters

The mass ordering of mean transverse momentum $$\langle$$p_T$$\rangle$$ and of the Fourier harmonic coefficient v₂ (p_T) of azimuthally anisotropic particle distributions in high energy hadron collisions is often interpreted as evidence for the hydrodynamic flow of the matter produced. We investigate an alternative initial state interpretation of this pattern in high-multiplicity proton-proton collisions at the LHC. The QCD Yang-Mills equations describing the dynamics of saturated gluons are solved numerically with initial conditions obtained from the color-glass-condensate-based impact-parameter-dependent glasma model. The gluons are subsequently fragmented into various hadron species employing the well established Lund string fragmentation algorithm of the pythia eventmore »« less

Measurement of the Sensitivity of Two-Particle Correlations in $$\mathcal{pp}$$ Collisions to the Presence of Hard Scatterings

Journal Article Aad, G.; Abbott, B.; Abeling, K.; ... - Physical Review Letters

A key open question in the study of multiparticle production in high-energy pp collisions is the relationship between the “ridge”—i.e., the observed azimuthal correlations between particles in the underlying event that extend over all rapidities—and hard or semihard scattering processes. In particular, it is not known whether jets or their soft fragments are correlated with particles in the underlying event. To address this question, two-particle correlations are measured in pp collisions at $$\sqrt{s}$$=13 TeV using data collected by the ATLAS experiment at the LHC, with an integrated luminosity of 15.8 pb^-1, in two different configurations. In the first case, chargedmore »« less

Multiplicity and transverse momentum dependence of two- and four-particle correlations in pPb and PbPb collisions

Journal Article Chatrchyan, S.; Khachatryan, V.; Sirunyan, A.; ... - Physics Letters. Section B

Measurements of two- and four-particle angular correlations for charged particles emitted in pPb collisions are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated luminosity of approximately 31 inverse nanobarns, were collected during the 2013 LHC pPb run at a nucleon-nucleon center-of-mass energy of 5.02 TeV by the CMS experiment. The results are compared to 2.76 TeV semi-peripheral PbPb collision data, collected during the 2011 PbPb run, covering a similar range of particle multiplicities. The observed correlations are characterized by the near-side (abs(Delta(phi)~0) associated pair yields and the azimuthal anisotropy Fourier harmonics (v[n]).more »« less

Ridge formation induced by jets in pp collisions at 7 TeV

Journal Article Hwa, Rudolph; Yang, C - Physical Review. C, Nuclear Physics

An interpretation of the ridge phenomenon found in pp collisions at 7 TeV is given in terms of enhancement of soft partons due to energy loss of semihard jets. A description of ridge formation in nuclear collisions can directly be extended to pp collisions since hydrodynamics is not used and azimuthal anisotropy is generated by semihard scattering. The observed ridge structure is then understood as a manifestation of soft-soft transverse correlation induced by semihard partons without long-range longitudinal correlation. Both the p{sub T} and multiplicity dependencies are well reproduced. Some predictions are made about other observables.
