Precision Measurement of Net-Proton-Number Fluctuations in Au + Au Collisions at RHIC

J. Adam, L. Adamczyk, I. Aggarwal, M. M. Aggarwal et autres

We report precision measurements on cumulants (C_{n}) and factorial cumulants (κ_{n}) of (net) proton number distributions up to fourth order in Au+Au collisions over center-of-mass energies sqrt[s_{NN}]=7.7-27 GeV from phase II of the Beam Energy Scan program at RHIC. (Anti)protons are selected …

Exclusive J/ψ, ψ(2s) , and e+e− pair production in Au+Au ultraperipheral collisions at the BNL Relativistic Heavy Ion Collider

M. I. Abdulhamid, B. E. Aboona, J. Adam, L. Adamczyk et autres

Measurements of exclusive $J/\ensuremath{\psi}, \ensuremath{\psi}(2s)$, and electron-positron (${e}^{+}{e}^{\ensuremath{-}}$) pair photoproduction in $\mathrm{Au}+\mathrm{Au}$ ultraperipheral collisions are reported by the STAR experiment at $\sqrt{{s}_{{}_{\mathrm{NN}}}}=200\phantom{\rule{4pt}{0ex}}\mathrm{GeV}$. We report several first measurements at the BNL Relativistic Heavy Ion Collider, which are (i) $J/\ensuremath{\psi}$ photoproduction with large momentum …

Multiplicity and event-scale dependent flow and jet fragmentation in pp collisions at $$ \sqrt{s} $$ = 13 TeV and in p–Pb collisions at $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV

S. Acharya, D. Adamová, G. Aglieri Rinella, M. Agnello et autres

A bstract Long- and short-range correlations for pairs of charged particles are studied via two-particle angular correlations in pp collisions at $$ \sqrt{s} $$ s = 13 TeV and p–Pb collisions at $$ \sqrt{s_{\textrm{NN}}} $$ s NN = 5 . 02 TeV. …

Measurements of long-range two-particle correlation over a wide pseudorapidity range in p–Pb collisions at $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV

S. Acharya, D. Adamová, G. Aglieri Rinella, M. Agnello et autres

A bstract Correlations in azimuthal angle extending over a long range in pseudorapidity between particles, usually called the “ridge” phenomenon, were discovered in heavy-ion collisions, and later found in pp and p–Pb collisions. In large systems, they are thought to arise from …

Strange hadron production in Au + Au collisions at s N N = 7.7 , 11.5, 19.6, 27, and 39 GeV

J. Adam, L. Adamczyk, J. R. Adams, J. K. Adkins et autres

Strange hadrons are an excellent probe for identifying the phase boundary and onset of deconfinement in the QCD phase diagram. The STAR Collaboration has performed precision measurements of the abundances and transverse-momentum distributions for 8 species of strange mesons and baryons, as …

Jet fragmentation transverse momentum measurements from di-hadron correlations in $$ \sqrt{\mathrm{s}}=7 $$ TeV pp and $$ \sqrt{s_{\mathrm{NN}}}=5.02 $$ TeV p–Pb collisions

S. Acharya, Fernando Torales Acosta, D. Adamová, S.P. Adhya et autres

Abstract The transverse structure of jets was studied via jet fragmentation transverse momentum (jT) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE experiment at the LHC. The highest transverse momentum particle in each event is used …

Longitudinal asymmetry and its effect on pseudorapidity distributions in Pb–Pb collisions at sNN=2.76 TeV

S. Acharya, J. Adam, D. Adamová, J. Adolfsson et autres

First results on the longitudinal asymmetry and its effect on the pseudorapidity distributions in Pb–Pb collisions at s NN = 2.76 TeV at the Large Hadron Collider are obtained with the ALICE detector. The longitudinal asymmetry arises because of an unequal number …

Evolution of the longitudinal and azimuthal structure of the near-side jet peak in Pb-Pb collisions at sNN=2.76 TeV

J. Adam, D. Adamová, M. M. Aggarwal, G. Aglieri Rinella et autres

In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher-${p}_{\mathrm{T}}$ trigger particle. Measurements of these correlations as a function of pseudorapidity ($\mathrm{\ensuremath{\Delta}}\ensuremath{\eta}$) and azimuthal ($\mathrm{\ensuremath{\Delta}}\ensuremath{\varphi}$) differences are used to extract the centrality and …
