x F Dependence of Drell-Yan Transverse Moemtum Broadening
Abstract
We analyze
x
F
dependence of Drell-Yan transverse momentum broadening in hadron-nucleus collisions. In terms of generalized factorization theorem, we show that the
x
F
dependence of transverse momentum broadening,
Δ<
q
2
T
>(
x
F
)
, can be calculated in perturbative QCD. We demonstrate that
Δ<
q
2
T
>(
x
F
)
is a good observable for studying the effects of initial-state multiple scattering and extracting quark-gluon correlation functions.
