DESCRIPTION:Speakers: Ian Balitsky (JLab/ODU)\nA typical factorization for
mula for production of a particle with a small transverse momentum in had
ron-hadron collisions is given\nby a convolution of two TMD parton densiti
es with cross section of production of the final particle by the two parto
ns. \nFor practical applications at a given transverse momentum\, though\
, one should estimate at what momenta \nthe power corrections to the TMD
factorization formula become essential. In this talk I present the resul
ts of calculation of\n first power corrections to TMD factorization formul
a for Z-boson production and Drell-Yan process in high-energy hadron-hadro
n collisions. \nAt the leading order in $N_c$ power corrections are expres
sed in terms of leading power TMDs by QCD equations of motion.\n\nhttps://
