Summing threshold logs in a parton shower [PDF]

, 2016
When parton distributions are falling steeply as the momentum fractions of the partons increases, there are effects that occur at each order in $\alpha_s$ that combine to affect hard scattering cross sections and need to be summed.

Double Higgs production at NNLO interfaced to parton showers in GENEVA

Journal of High Energy Physics, 2023
In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the Geneva framework and working in the heavy-top-limit approximation.

Matching the Nagy-Soper parton shower at next-to-leading order [PDF]

, 2015
We present an MC@NLO-like matching of next-to-leading order QCD calculations with the Nagy-Soper parton shower. An implementation of the algorithm within the HELAC-DIPOLES Monte Carlo generator is used to address the uncertainties and ambiguities of the ...

Modified Fragmentation Function from Quark Recombination

, 2005
Within the framework of the constituent quark model, it is shown that the single hadron fragmentation function of a parton can be expressed as a convolution of shower diquark or triquark distribution function and quark recombination probability, if the ...
