We have the pleasure to invite you to the Particle Theory Seminar on Tuesday, October 24 at 12:15, which will be given by
James Whitehead (IFJ PAN)
„The KrkNLO method for NLO parton shower matching".
'Matched' calculations combining the next-to-leading-order (NLO) accuracy of perturbative QCD with the logarithmic resummation of a parton shower are a key workhorse driving LHC phenomenology in the precision era. The KrkNLO method for NLO parton shower matching uses multiplicative reweighting and a convenient choice of PDF factorisation scheme to produce matched NLO + parton shower predictions. By construction, it guarantees positive weights. I will present an introduction to the theory of NLO matching, an overview of the KrkNLO method, and phenomenological results from the implementation of new processes in Herwig 7.
The seminar will be in in-person mode in the seminar room D-2-02, but you can also attend remotely through Zoom.
