Measurements of charged-particle multiplicity dependence of higher-order net-proton cumulants in $p$+$p$ collisions at $\sqrt{s} =$ 200 GeV from STAR at RHIC

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona, J. Adam et autres

We report on the charged-particle multiplicity dependence of net-proton cumulant ratios up to sixth order from $\sqrt{s}=200$ GeV $p$+$p$ collisions at the Relativistic Heavy Ion Collider (RHIC). The measured ratios $C_{4}/C_{2}$, $C_{5}/C_{1}$, and $C_{6}/C_{2}$ decrease with increased charged-particle multiplicity and rapidity acceptance. …

Event-by-event correlations between Λ (Λ¯) hyperon global polarization and handedness with charged hadron azimuthal separation in Au+Au collisions at sNN=27 GeV from STAR

Global polarizations ($P$) of $\mathrm{\ensuremath{\Lambda}} (\overline{\mathrm{\ensuremath{\Lambda}}})$ hyperons have been observed in noncentral heavy-ion collisions. The strong magnetic field primarily created by the spectator protons in such collisions would split the $\mathrm{\ensuremath{\Lambda}}$ and $\overline{\mathrm{\ensuremath{\Lambda}}}$ global polarizations ($\mathrm{\ensuremath{\Delta}}P={P}_{\mathrm{\ensuremath{\Lambda}}}\ensuremath{-}{P}_{\overline{\mathrm{\ensuremath{\Lambda}}}}<0$). Additionally, quantum chromodynamics predicts topological charge …
