Antinucleus Production at RHIC
نویسنده
چکیده
Light antinuclei may be formed in relativistic heavy ion collisions via final state coa-lescence of antinucleons. The yields of antinuclei are sensitive to primordial antinucleon production, the volume of the system at kinetic freeze-out, and space-momentum correlations among antinucleons at freeze-out. We report here preliminary STAR results on ¯ d and 3 He production in 130A GeV Au+Au collisions. These results are examined in a coalescence framework to elucidate the space-time structure of the antinucleon source.

Revisiting Wγ production at RHIC
We discuss Wγ production in polarized p p collisions at RHIC energy. We point out that the RHIC collider has two advantages over other hadron colliders to measure the characteristic feature of Wγ production: (1) the RHIC energy is not so high and (2) the polarized beams are available. We calculate the tree level cross section for Wγ production using a generic spin basis for W and discuss both t...
متن کاملParticle production at RHIC energies
This paper presents recent results from the BRAHMS experiment at RHIC; including results on particle production in rapidity space extending from y=0 to y ∼ 3 and on the transverse momentum distribution of fully identified charged particles. These results were obtained from the 5% most central Au-Au collisions recorded during RHIC Run-2 at √ sNN = 200 GeV.
متن کاملHidden Charm Production in Au + Au Collisions at RHIC Energies
We consider various possibilities for the production of open charm and J/ψ at RHIC energies in heavy ion collisions. We discuss several recently developed pictures for J/ψ production and argue that a measurement at RHIC energies is crucial for disentangling these different descriptions. Typeset using REVTEX
متن کاملStatistical hadronization of charm in heavy-ion collisions at SPS, RHIC and LHC
We study the production of charmonia and charmed hadrons in nucleus-nucleus collisions at SPS, RHIC, and LHC energies within the framework of the statistical hadronization model. Results from this model are compared to the measured yields and centrality dependence of J/ψ production at SPS and RHIC energies. We explore and contrast the centrality dependence of the production of mesons with open ...
متن کاملJet Production in Polarized pp Collisions at RHIC
One of the primary goals of the RHIC spin program is to determine the gluon polarization distribution within the proton. At leading order, pp collisions at RHIC involve a mixture of quark-quark (qq), quark-gluon (qg), and gluon-gluon (gg) scattering processes, with qg and gg contributions dominating. This makes RHIC an ideal place to study gluon polarization. For the past several years, the STA...
