Elliptic flow of $π^{0}$ mesons in Cu $+$ Au collisions at $s_{_{N N}} = 200$ GeV and U $+$ U at $s_{_{N N}} = 193$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +386

The second-order azimuthal anisotropy coefficients ( $v_{2}$ ) of neutral $π$ mesons ( $π^{0}$ ) have been measured as a function of the transverse momentum ( $p_{T}$ ) and centrality of Cu $+$ …

First measurement of $I ¨ $ meson production in 30 GeV proton-nucleus reactions via di-electron decay at J-PARC

PARC E16 collaboration, Satomi Nakasuga, Yuhei Morino +44

We present the first measurement of the production of the $I ¨ $ meson in 30 GeV proton-nucleus interactions on carbon and copper targets via the di-electron decay channel. The measu…

Transverse single-spin asymmetry of forward $I^\cdot$ mesons in $p^{↑} + p$ collisions at $s = 200$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +380

Utilizing the 2012 transversely polarized proton data from the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, the forward $I^\cdot$ -meson transverse single-spin asym…

Velocity dependence of the mass modifications of $I ¨ $ and $I ¨ $ mesons in 12 GeV $p + A$ reactions

Wataru Nakai, Kazuya Aoki, Junsei Chiba +26

This study measured the invariant mass spectra of $I ¨ $ and $I ¨ $ mesons in the $e^{+} e^{-}$ decay channel for 12 GeV (12.9 GeV/ $c$ ) $p + C$ and $p + Cu$ reactions ($\sqrt{…

Cross sections of $I^\cdot$ mesons in $p$ $+$ $p$ collisions at forward rapidity at $s = 500$ GeV and central rapidity at $s = 510$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +497

We present the first measurements of the forward and midrapidity $I^\cdot$ -meson cross sections from $p$ $+$ $p$ collisions at $s = 500$ and $510$ ~GeV, respectively. We also report t…

Analysis of spectral modification of $I ¨ $ mesons at finite density using a transport approach in the 12 GeV pA reactions

PS E325 Collaboration, Masaya Ichikawa, Philipp Gubler +26

The hadron spectrum at finite density is an important observable for exploring the origin of hadron masses. In the KEK-PS E325 experiment, the di-electron decays of phi mesons insi…
