Identified hadron spectra at large transverse momentum in p+p and d+Au collisions at,root(NN)-N-S=200 GeV
Original language description
We present the transverse momentum (PT) spectra for identified charged pions, protons and anti-protons from p + p and d + Au collisions at root sNN = 200 GeV. The spectra are measured around midrapidity (vertical bar y vertical bar < 0.5) over the rangeof 0.3 < PT < 10 GeV/c with particle identification from the ionization energy loss and its relativistic rise in the time projection chamber and time-of-flight in STAR. The charged pion and proton + anti-proton spectra at high PT in p + p and d + Au collisions are in good agreement with a phenomenological model (EPOS) and with next-to-leading order perturbative quantum chromodynamic (NLO pQCD) calculations with a specific fragmentation scheme and factorization scale. We found that all proton, anti-proton and charged pion spectra in p + p collisions follow x(T)-scating for the momentum range where particle production is dominated by hard processes (p(T) greater than or similar to 2 GeV/c).
