J/$\psi$ and $\psi (2S)$ measurement in $p$+$p$ collisions at $\sqrt{s}=$ 200 and 500 GeV in the STAR experiment

Abstract

In this paper, results on the J/$\psi$ cross section and polarization measured via the dielectron decay channel at mid-rapidity in $p+p$ collisions at $\sqrt{s}$ = 200 and 500 GeV in the STAR experiment are discussed. The first measurement of $\psi (2S)$ to J/$\psi$ ratio at $\sqrt{s}$ = 500 GeV is also reported.
