SUMMARY:Transverse momentum resummation: general formalism and the case of
  diphoton production at LHC - Francesco Coradeschi (Florence University)

DESCRIPTION:After reviewing the b-space transverse momentum (qT) resummati
 on formalism in the context of hadron collisions\, focusing on the simples
 t case in which a colorless final state is produced alongside unresolved s
 trongly-interacting particles\, I will show the latest results for the pro
 duction of diphoton pairs at the LHC at NNLO. Besides restoring the predic
 tivity of the perturbative QCD prediction at low qT\, the resummation impr
 oves the agreement of the theoretical prediction with the experimental dat
 a. It is worth noting that the resummation formalism\, which is by now ver
 y well-established\, has several \npowerful features\, such as universalit
 y (most of the coefficients needed to implement the calculation are proces
 s-independent) and flexibility\, allowing for the prediction of more gener
 al distributions than just the qT spectrum. In fact\, the structure of the
  resummation formula is closely related to\, and helps elucidate\, the gen
 eral structure of IR singularities in QCD.
