Azimuthal transverse single-spin asymmetries of inclusive jets and identified hadrons within jets from polarized pp collisions at s=200 GeV

M. S. Abdallah, B. E. Aboona, J. Adam, L. Adamczyk et autres

The STAR Collaboration reports measurements of the transverse single-spin asymmetries, ${A}_{N}$, for inclusive jets and identified ``hadrons within jets'' production at midrapidity from transversely polarized $pp$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$, based on data recorded in 2012 and 2015. The inclusive jet …

Measurement of inclusive charged-particle jet production in Au + Au collisions at s N N = 200 GeV

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

The STAR Collaboration at the Relativistic Heavy Ion Collider reports the first measurement of inclusive jet production in peripheral and central Au+Au collisions at $\sqrt{{s}_{NN}}=200$ GeV. Jets are reconstructed with the anti-${k}_{T}$ algorithm using charged tracks with pseudorapidity $|\ensuremath{\eta}|<1.0$ and transverse momentum …

Measurements of the transverse-momentum-dependent cross sections of J/ψ production at mid-rapidity in proton+proton collisions at s=510 and 500 GeV with the STAR detector

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

We present measurements of the differential cross sections of inclusive $J/\ensuremath{\psi}$ meson production as a function of transverse momentum (${p}_{T}^{J/\ensuremath{\psi}}$) using the ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and ${e}^{+}{e}^{\ensuremath{-}}$ decay channels in $\mathrm{proton}+\mathrm{proton}$ collisions at center-of-mass energies of 510 and 500 GeV, respectively, recorded by the …
