SUMMARY:Radiation beyond the soft approximation - Chris White (Glasgow)
DTSTART:20150324T150000Z

CONTACT:Alexander Mitov
DESCRIPTION:It is well-known that large logarithms arise in scattering amp
 litudes at all orders in perturbation theory\, that have to be summed up t
 o all orders (“resummed") in order to produce reliable collider predicti
 ons. These terms arise when emitted gauge bosons become “soft" (have zer
 o 4-momentum)\, and many approaches exist for classifying them. Until rece
 ntly\, much less was known about how to go beyond this approximation. This
  is important for improving the precision of QCD predictions\, but also ha
 s more formal applications. In this talk\, I will summarise work done in t
 his area\, and present a recently obtained factorisation formula for next-
 to-soft and collinear effects. If time permits\, I will also look at relat
 ions between QCD and gravity.
