Alternative methods to measure global polarization of hyperons
Irfan Siddique, Zuo-tang Liang, Michael Annan Lisa +2
We propose alternative methods to measure the global polarization of hyperons. These methods involve event averages of proton's and 's momenta in the lab frame. We carry out…
Collision Energy Dependence of Moments of Net-Kaon Multiplicity Distributions at RHIC
STAR Collaboration, L. Adamczyk, J. R. Adams +343
Fluctuations of conserved quantities such as baryon number, charge, and strangeness are sensitive to the correlation length of the hot and dense matter created in relativistic heav…
Beam-Energy Dependence of Directed Flow of , , , and in Au+Au Collisions
STAR Collaboration, L. Adamczyk, J. R. Adams +342
Rapidity-odd directed flow measurements at midrapidity are presented for , , , and at 7.7, 11.5, 14.5, 19.6, 27, 39, 62.4 and 200 GeV…
Azimuthal transverse single-spin asymmetries of inclusive jets and charged pions within jets from polarized-proton collisions at GeV
STAR Collaboration, L. Adamczyk, J. R. Adams +342
We report the first measurements of transverse single-spin asymmetries for inclusive jet and jet + production at midrapidity from transversely polarized proton-proton col…
Coherent diffractive photoproduction of mesons on gold nuclei at RHIC
STAR Collaboration, L. Adamczyk, J. K. Adkins +342
The STAR Collaboration reports on the photoproduction of pairs in gold-gold collisions at a center-of-mass energy of 200 GeV/nucleon-pair. These pion pairs are produced wh…
Global hyperon polarization in nuclear collisions: evidence for the most vortical fluid
STAR Collaboration
The extreme temperatures and energy densities generated by ultra-relativistic collisions between heavy nuclei produce a state of matter with surprising fluid properties. Non-centra…
