`QCD for boosted top-quark production'

Abstract:
The LHC is starting to explore top quark pair production in the boosted regime,
where the energies of the top quarks are much larger than m_t.  In this talk
some of the theoretical challenges in the calculation of QCD corrections in
this regime are explained, and a factorization formalism useful for resumming
soft and small-mass logarithms in this regime is presented.
