The inclusive charged particle transverse momentum distribution is measured in proton-proton collisions at $\sqrt{s} = 900$~GeV at the LHC using the ALICE detector. The measurement is performed in ...the central pseudorapidity region $(|\eta|<0.8)$ over the transverse momentum range $0.15
The BRAHMS probes the hot and dense nuclear matter at the RHIC which has reached its design
energy of psNN = 200 GeV for Au + Au collisions. The BRAHMS uses magnetic spectrometers
for hadrons ...covering a large phase space 0 < y < 4 with good particle identification and momentum
resolution. A comprehensive investigation of multiplicity distributions of emitted charged particles
is carried out. Ratios of yields of antiparticles to particles are also measured as a function of rapidity.
Rapidity dependent net-proton yield indicates that substantial transparency has been achieved in
these collisions. Transverse momentum spectra of charged hadrons are measured up to 5 GeV/c
which indicates a significant medium eect when compared to nucleon + nucleon reference spectra. KCI Citation Count: 3
