Identified hadron compositions in p+p and Au+Au collisions at high transverse momenta at $\sqrt{s_{{}_{NN}}}=200$ GeV

STAR Collaboration

We report transverse momentum ($p_T\le 15$ GeV/$c$) spectra of ${\pi }^{\pm }$, $K^{\pm }$, $p$, $\bar{p}$, $K_S^0$, and ${\rho }^0$ at mid-rapidity in p+p and Au+Au collisions at $\sq…
