Color Transfer Enhancement for Heavy Quarkonium Production
Gouranga C. Nayak, Jian-Wei Qiu, George Sterman
We study the transfer of color between a heavy quark pair and an unpaired heavy quark or antiquark moving at a nonrelativistic velocity with respect to the pair. We find that the o…
Transverse momentum dependence of the angular distribution of the Drell-Yan process
Edmond L Berger, Jian-Wei Qiu, Ricardo A. Rodriguez-Pedraza
We calculate the transverse momentum Q_{\perp} dependence of the helicity structure functions for the hadroproduction of a massive pair of leptons with pair invariant mass Q. These…
Transverse momentum broadening of vector bosons in heavy ion collisions at the LHC
Zhong-Bo Kang, Jian-Wei Qiu
We calculate in perturbative QCD the transverse momentum broadening of vector bosons in heavy ion collisions at the Large Hadron Collider (LHC). We predict transverse momentum broa…
Angular distribution of leptons from the decay of massive vector bosons
Edmond L. Berger, Jian-Wei Qiu, Ricardo A. Rodriguez-Pedraza
We examine the transverse momentum dependence of the helicity structure functions for massive vector bosons of mass in hadron reactions. We demonstrate that large log…
Color Transfer in Associated Heavy-Quarkonium Production
Gouranga C. Nayak, Jian-Wei Qiu, George Sterman
We study the production of heavy quarkonium in association with an additional heavy pair. We argue that important contributions may come from phase space regions where three heavy…
k_T factorization is violated in production of high-transverse-momentum particles in hadron-hadron collisions
John Collins, Jian-Wei Qiu
We show that hard-scattering factorization is violated in the production of high-p_T hadrons in hadron-hadron collisions, in the case that the hadrons are back-to-back, so that k_T…
