Description

The hybrid kT-factorization formula, for which one initial-state parton
momentum is space-like and carries non-vanishing transverse components while
the other is on-shell, is promoted to NLO for arbitrary processes. We identify
all soft and collinear divergencies in the partonic cross section, and
recognize that the non-cancelling ones can be attributed to PDF evolution,
evolution kernel, and target impact factors. Coincidentally, we recover known
expressions for inclusive NLO impact factor corrections both for quarks and
gluons.
