Investigation of Experimental Observables in Search of the Chiral Magnetic Effect in Heavy-ion Collisions in the STAR experiment
S. Choudhury,X. Dong,J. L. Drachenberg,J. C. Dunlop,ShinIchi Esumi,Yicheng Feng,E. Finch,Yu Hu,Jiangyong Jia,Jerome Lauret,Wei Li,Jinfeng Liao,Y. Lin,Michael Annan Lisa,Takafumi Niida,Robert L. Ray,M. Sergeeva,Diyu Shen,Shuzhe Shi,Paul Sorensen,A. H. Tang,Prithwish Tribedy,Gene Van Buren,Sergei A. Voloshin,Fuqiang Wang,Gang Wang,Hao-jie Xu,Z. Xu,Nanxi Yao,Jie Zhao +29 more
TL;DR: In this paper, the authors investigated three pertinent experimental approaches: the $R$ correlator, the signed balance functions, and the π-gamma correlator to verify the equivalence in the kernel-component observables among these methods.

Statistical-noise reduction in correlation analysis of high-energy nuclear collisions with event-mixing
Robert L. Ray,P. Bhattarai +1 more
TL;DR: In this article, the error propagation and statistical noise reduction method of Reid and Trainor for two-point correlation applications in high-energy collisions is extended to include particle-pair references constructed by mixing two particles from all event-pair combinations within event subsets of arbitrary size.
Two-particle correlations on transverse momentum: an untapped resource for studying relativistic heavy-ion collision dynamics
Robert L. Ray,A. Jentsch +1 more
TL;DR: Two-particle correlation projections onto two-dimensional transverse momentum coordinates (pt 1, pt 2 ) allow access to properties of the relativistic heavy-ion collision system which are complementary to that studied using angular correlations.
Investigation of experimental observables in search of the chiral magnetic effect in heavy-ion collisions in the STAR experiment
S. Choudhury,X. Dong,J. L. Drachenberg,J. C. Dunlop,ShinIchi Esumi,Yicheng Feng,E. Finch,Yu Hu,Jiangyong Jia,Jerome Lauret,Wei Li,Jinfeng Liao,Y. Lin,Michael Annan Lisa,Takafumi Niida,Robert L.

TL;DR: In this paper, the authors exploit simple Monte Carlo simulations and a realistic event generator (EBE-AVFD) to verify the equivalence of the core components among these methods and to ascertain their sensitivities to the CME signal and the background contributions for the isobar collisions at the RHIC.
Challenging claims of ?elliptic flow? by comparing azimuth quadrupole and jet-related angular correlations from Au?Au collisions at $\sqrt{{{s}_{NN}}}$ = 62 and 200 GeV
TL;DR: In this paper, the authors compare measured jet-related and flow-related data systematics and determine the jet's contribution to azimuth correlation components and a non-joint quadrupole that might represent "elliptic flow".
