Power corrections to TMD factorization for Zboson production
A typical factorization formula for production of a particle with a small transverse momentum in hadronhadron collisions is given by a convolution of two leadingtwist TMD parton densities with cross section of production of the final particle by the two partons. For practical applications at a given transverse momentum, though, one should estimate at what momenta the power corrections to TMD factorization formula due to highertwist operators become essential. In this paper we calculate the first power corrections to TMD factorization formula for Zboson production and DrellYan process in highenergy hadronhadron collisions. At the leading order in Nc power corrections are expressed in terms of leadingtwist TMDs by QCD equations of motion.
