A new subtraction scheme at NLO exploiting the privilege of kT-factorization

A bstract We present a subtraction method for the calculation of real-radiation integrals at NLO in hybrid k T -factorization. The main difference with existing methods for collinear factorization is that we subtract the momentum recoil, occurring due to the mapping from an ( n + 1)-particle phase space to an n -particle phase space, from the initial-state momenta, instead of distributing it over the final-state momenta.
