Energy Loss in Nuclear Drell-Yan Process
By means of the nuclear parton distributions which can be used to provide a good explanation for the EMC effect in the whole x range, we investigate the energy loss effect in nuclear Drell-Yan process. When the cross section of lepton pair production is considered varying with the center-of-mass energy of the nucleon-nucleon collision, we find that the nuclear Drell-Yan(DY) ratio is suppressed ...
متن کاملNuclear dependence in transverse momentum distribution for Drell-Yan pair
Recently, it was found experimentally that the transverse momentum distribution of Drell-Yan pair in hadron-nucleus collisions shows nuclear dependence not linearly proportional to A, the atomic number of the target [1]. In addition, the average of squared transverse momentum, 〈q T 〉, grows approximately as A 1/3 [1,2]. This observed non-linear nuclear dependence indicates that multiple-scatter...
متن کاملStrong nuclear enhancement in intermediate mass Drell-Yan production
We calculate nuclear effect in Drell-Yan massive lepton-pair production in terms of parton multiple scattering in Quantum Chromodynamics (QCD). We present the nuclear modification to inclusive Drell-Yan cross section dσ/dQ2 in terms of multiparton correlation functions. By extracting the size of the correlation functions from measured Drell-Yan transverse momentum broadening in nuclear medium, ...
متن کاملNuclear dependence in Drell-Yan transverse momentum distribution
We calculate the nuclear enhancement in Drell-Yan transverse momentum distribution in hadron-nucleus collisions. In terms of multiple scattering picture, we compute the contributions from double scattering. Applying the generalized factorization theorem, we express the nuclear enhancement in terms of twist-4 nuclear parton correlation functions. We demonstrate that these twist-4 nuclear parton ...
متن کاملNuclear Enhanced Higher-Twist Effects in the Drell-Yan Process
We calculate the Drell-Yan cross section, resolving the full kinematics of the lepton pair, at high transverse momentum for hadron nucleus collisions. We use the general framework of Luo, Qiu and Sterman to calculate double scattering contributions that are of twist-4 and demonstrate their nuclear enhancement. By comparing single and double scattering at RHIC energies we find that double scatte...
