Muon Pair Production in Relativistic Nuclear Collisions
The exclusive production of one μ+μ− pair in collisions of two ultra-relativistic nuclei is considered. We present the simple method for calculation of the Born cross section for this process. Then we found that the Coulomb corrections to this cross section (which correspond to multi-photon exchange of the produced μ with nuclei) are small while the unitarity corrections are large. This is in s...
متن کاملDifferent Nuclear Dependence of J / ψ and ψ ′ Production in p - A and A - p Collisions ∗
While presently available p-A data observe that the nuclear dependence of J/ψ and ψ production is the same within errors, we show that different nuclear dependence of J/ψ and ψ production in the kinematic region uncovered by the present p-A data can be predicted based on two different nuclear absorption scenarios. It is found that the predicted production ratio σ(ψ)/σ(J/ψ) at positive xF in A-p...

متن کاملInclusive J / ψ and ψ ( 2 S ) Production from B Decay in pp̄ Collisions
Using information on B-meson fragmentation functions from CERN LEP 1 and adopting the nonrelativistic QCD factorization formalism proposed by Bodwin, Braaten, and Lepage, we predict the transverse-momentum distribution of J/ψ mesons originating from the inclusive decays of b hadrons produced in pp̄ collisions at the Fermilab Tevatron. We determine the relevant colour-octet charmonium matrix elem...
