34. Threshold factorization of the Drell-Yan quark-gluon channel and two-loop soft functions at NLP

Dr Sebastian Jaskiewicz (IPPP, Durham University)

29/03/2023, 14:00

Extension of factorization formulas beyond leading power within Soft Collinear Effective Theory (SCET) in recent years has not proved straightforward due to appearance of endpoint divergences and complicated functions with extra dependence on convolution variables. In this talk, I will discuss the basis for a resummation of the quark-gluon channel of the Drell-Yan process at threshold at...

17. NNLO jet and beam functions: Automation, distributions and jet clustering

Kevin Brune

We present an extension of our automated framework for the calculation of jet and beam function to next-to-next-to-leading order in perturbation theory. In particular, we will present first results for quark and gluon jet functions that involve non-trivial phase-space constraints from jet algorithms like the winner-take-all axis recombination scheme. Moreover, we will report on a novel...

25. Bottom mass corrections to boosted-top cross section

Mr Alejandro Bris (IFT-UAM)

29/03/2023, 15:00

In this talk we present the computation of the secondary massive quark corrections to the bHQET thrust distribution at NNLO. The missing pieces of the corresponding factorization theorem at this order are the jet and hard functions.

For the calculation of the massive bubble diagrams we employ the Mellin Barnes representation for the dispersive integral, that enables expressing the result as...
