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

Density fluctuations near the QCD critical point can be probed via an intermittency analysis in relativistic heavy-ion collisions. We report the first measurement of intermittency in Au+Au collisions at $\sqrt{s_{NN}}$ = 7.7-200 GeV measured by the STAR experiment at the Relativistic Heavy …

Measurement of e + e − Momentum and Angular Distributions from Linearly Polarized Photon Collisions

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

The Breit-Wheeler process which produces matter and antimatter from photon collisions is experimentally investigated through the observation of 6085 exclusive electron-positron pairs in ultraperipheral $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. The measurements reveal a large fourth-order angular modulation of $\mathrm{cos}4\mathrm{\ensuremath{\Delta}}\ensuremath{\phi}=(16.8\ifmmode\pm\else\textpm\fi{}2.5)%$ and smooth …

Nonmonotonic Energy Dependence of Net-Proton Number Fluctuations

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

Nonmonotonic variation with collision energy (sqrt[s_{NN}]) of the moments of the net-baryon number distribution in heavy-ion collisions, related to the correlation length and the susceptibilities of the system, is suggested as a signature for the quantum chromodynamics critical point. We report the …

Polarization of Λ ( Λ ¯ ) Hyperons along the Beam Direction in Au + Au Collisions at s N N = 200 GeV

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

The Λ (Λ[over ¯]) hyperon polarization along the beam direction has been measured in Au+Au collisions at sqrt[s_{NN}]=200 GeV, for the first time in heavy-ion collisions. The polarization dependence on the hyperons' emission angle relative to the elliptic flow plane exhibits a …

Measurement of the HΛ3 lifetime in Au+Au collisions at the BNL Relativistic Heavy Ion Collider

L. Adamczyk, J. R. Adams, J. K. Adkins, G. Agakishiev et autres

An improved measurement of the $_{\mathrm{\ensuremath{\Lambda}}}^{3}\mathrm{H}$ lifetime is presented. In this paper, the mesonic decay modes $_{\mathrm{\ensuremath{\Lambda}}}^{3}\mathrm{H}\ensuremath{\rightarrow}^{3}\mathrm{He}$ + ${\ensuremath{\pi}}^{\ensuremath{-}}$ and $_{\mathrm{\ensuremath{\Lambda}}}^{3}\mathrm{H}\ensuremath{\rightarrow}d+p+{\ensuremath{\pi}}^{\ensuremath{-}}$ are used to reconstruct the $_{\mathrm{\ensuremath{\Lambda}}}^{3}\mathrm{H}$ from Au+Au collision data collected by the STAR collaboration at Relativistic Heavy Ion Collider (RHIC). …

B. Abelev, J. Adam, D. Adamová, A. Adare et autres

This publication describes the methods used to measure the centrality of inelastic Pb-Pb collisions at a center-of-mass energy of 2.76 TeV per colliding nucleon pair with ALICE. The centrality is a key parameter in the study of the properties of QCD matter …

Correlations of two charged identical kaons (${\mathrm{K}}^{\mathrm{ch}}{\mathrm{K}}^{\mathrm{ch}}$) are measured in $pp$ collisions at $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ by the ALICE experiment at the Large Hadron Collider (LHC). One-dimensional ${\mathrm{K}}^{\mathrm{ch}}{\mathrm{K}}^{\mathrm{ch}}$ correlation functions are constructed in three multiplicity and four transverse momentum ranges. The ${\mathrm{K}}^{\mathrm{ch}}{\mathrm{K}}^{\mathrm{ch}}$ …
