Description
I present a QCD calculation of the transverse momentum distributions of
Higgs bosons, and of photon pairs produced by 'background' QCD
subprocesses, including all-orders soft-gluon resummation valid at
next-to-next-to-leading logarithmic accuracy. Resummation is needed to
obtain predictions valid in the ranges of transverse momentum where the
cross sections are largest. I compare theresults with data from the
Fermilab Tevatron and make predictions for the Large Hadron Collider. The
QCD 'background' is shown to have a softer spectrum than the signal.
