  We describe the program KKMC-hh, which calculates Z boson processes in
hadronic collisions using coherent exclusive exponentiation (CEEX) with exact
second-order photonic corrections at next-to-leading log and first-order weak
vertex corrections, including initial and final state photonic radiation and
initial-final interference. We describe current applications to precision
forward-backward asymmetry calculations for the measurement of the electroweak
mixing angle at the LHC.
