Muon production in the forward and backward rapidities in dAu collisions at RHIC
We have developed new techniques to detect hadrons with the PHENIX muon spectrometers. This allows us to study the centrality dependent nuclear modification factor RCP with high pT hadrons in both forward (d direction) and backward (Au direction) rapidities, 1 < |η| < 2, in d-Au collisions atsNN = 200GeV . Preliminary results show a suppression (enhancement) of high pT hadron production in cent...

We have developed new techniques to detect hadrons with the PHENIX muon spectrometers. This allows us to study the centrality dependent nuclear modification factor RCP with high pT hadrons in both forward (d direction) and backward (Au direction) pseudo-rapidities, 1 < |η| < 2, in d-Au collisions at √ sNN = 200GeV . Preliminary results show a suppression (enhancement) of high pT hadron producti...
متن کاملThe STAR forward pion production in dAu collisions and dynamics of production of recoil jets
Very recently the STAR collaboration reported measurement of the probability, P , for emission of at least one hadron with pt ≥ 0.5GeV/c, |η| ≤ 0.75 in association with production of a very forward high pt neutral pion in pp and dAu collisions. We calculate the A-dependence of the hard contributions to P assuming conventional relationship between the number of wounded nucleons and the hadron mu...
متن کاملCorrelations in the STAR forward pion production in dAu collisions and energy losses in black disc regime
We explain that in the black disc QCD regime (BDR) in difference from the moderate x regime very forward partons propagating through the nuclear matter should loose significant, increasing with energy and atomic number fraction of their initial energy as a result of dominance of inelastic interactions, causality and energy-momentum conservation. We evaluate these small x energy losses and find ...
متن کاملEnergy losses in the black disc regime and correlation effects in the STAR forward pion production in dAu collisions
We argue that in the small x processes, in the black disc QCD regime (BDR) a very forward parton propagating through the nuclear matter should loose a significant and increasing with energy and atomic number fraction of its initial energy as a result of dominance of inelastic interactions, causality and energy-momentum conservation. We evaluate these energy losses and find them to lead to the s...
