Merging the benefits from the resummation of collinear-enhanced
terms and from the higher precision provided by the next-to-leading order
results has been one of the main goal in the high-energy particle physics
in the last few years. In this talk, I will give a brief introduction to
the POWHEG method, that successfully implements this merging, and I will
comment on a few physical results obtained for several processes at the
LHC.
