Subatomic Heroes
Anshika Bansal, Guido Bell, Aritra Biswas +44
Sharing the amazing achievements of the (particle) physics world with the general public is at the heart of the mission of the Subatomic Heroes, based at the University of Siegen,…
Automated Calculation of Beam Functions at NNLO
Guido Bell, Kevin Brune, Goutam Das +1
We present an automated framework for the calculation of beam functions that describe collinear initial-state radiation at hadron colliders at next-to-next-to leading order (NNLO)…
The NNLO quark beam function for jet-veto resummation
Guido Bell, Kevin Brune, Goutam Das +1
We consider the quark beam function that describes collinear initial-state radiation that is constrained by a veto on reconstructed jets. As the veto is imposed on the transverse m…
Muon-electron backward scattering: a prime example for endpoint singularities in SCET
Guido Bell, Philipp Böer, Thorsten Feldmann
We argue that energetic muon-electron scattering in the backward direction can be viewed as a template case to study the resummation of large logarithms related to endpoint diverge…
Automation of Beam and Jet functions at NNLO
Guido Bell, Kevin Brune, Goutam Das +1
We present a novel framework to streamline the calculation of jet and beam functions to next-to-next-to-leading order (NNLO) in perturbation theory. By exploiting the infrared beha…
Generic dijet soft functions at two-loop order: uncorrelated emissions
Guido Bell, Rudi Rahn, Jim Talbert
We extend our algorithm for automating the calculation of two-loop dijet soft functions to observables that do not obey the non-Abelian exponentiation theorem, i.e. to those that r…
