"NNLOCAL: Episode III - Revenge of the integrals”


címmel tartandó szemináriumára.


Kivonat:



About eight months ago in a seminar room not that far away...

G. Somogyi has discussed the extension of the CoLoRFulNNLO scheme to hadronic 
scattering processes. This scheme allows for a proper treatment of kinematic 
divergences that plague perturbative calculations. It achieves this by 
setting up approximate cross sections that capture the infrared behavior of 
the partonic ones. Their construction is based on the standard infrared 
factorization theorems of quantum chromodynamics and, upon subtraction, one 
is left with inherently finite quantities. The subtractions then need to be 
integrated over the phase space of the unresolved emissions and added back. 
For a subset of the approximate cross sections, this integration is performed 
using integration-by-parts identities and differential equations, as was 
explained during P. Mukherjee’s seminar last February. In this talk, we 
describe how the remaining subtractions are integrated. We provide a general 
overview of the necessary steps and highlight the plethora of modern methods 
required to obtain the final result.
