NNLO initial-state corrections to
Yizhou Fang, Sara Gündogdu, Sophie Kollatzsch +3
We present initial-state corrections to at next-to-next-to-leading-order in QED for several experimentally motivated scenarios up to a few GeV. We include…
Low-energy at NNLO in QED
Tim Engel, Marco Rocco, Adrian Signer +1
We present a fully differential computation of at next-to-next-to-leading order in QED. The process has been implemented into McMule, completing its set of next-t…
Disperon QED
Yizhou Fang, Sophie Kollatzsch, Marco Rocco +3
We present disperon QED, a method to deal with data input in loop processes in Monte Carlo codes. It relies on dispersion relations, automated tools such as OpenLoops, effective fi…
McMule -- a Monte Carlo generator for low energy processes
Yannick Ulrich
McMule, a Monte Carlo for MUons and other LEptons, implements many major QED processes at NNLO (eg. , , , , ) including e…
Radiative corrections and Monte Carlo tools for low-energy hadronic cross sections in collisions
Riccardo Aliberti, Paolo Beltrame, Ettore Budassi +32
We present the results of Phase I of an ongoing review of Monte Carlo tools relevant for low-energy hadronic cross sections. This includes a detailed comparison of Monte Carlo code…
Radiative Corrections: From Medium to High Energy Experiments
Andrei Afanasev, Jan C. Bernauer, Peter Blunden +16
Radiative corrections are crucial for modern high-precision physics experiments, and are an area of active research in the experimental and theoretical community. Here we provide a…
High-precision muon decay predictions for ALP searches
P. Banerjee, A. M. Coutinho, T. Engel +3
We present an improved theoretical prediction of the positron energy spectrum for the polarised Michel decay . In addition to the full next-to-next-to-leadin…
Lepton pair production at NNLO in QED with EW effects
Sophie Kollatzsch, Yannick Ulrich
We present a fully differential calculation of lepton pair production, taking into account the dominant next-to-next-to-leading order QED corrections as well as next-to-leading ord…
Universal structure of radiative QED amplitudes at one loop
Tim Engel, Adrian Signer, Yannick Ulrich
We present two novel results about the universal structure of radiative QED amplitudes in the soft and in the collinear limit. On the one hand, we extend the well-known Low-Burnett…
Bhabha scattering at NNLO with next-to-soft stabilisation
Pulak Banerjee, Tim Engel, Nicolas Schalch +2
A critical subject in fully differential QED calculations originates from numerical instabilities due to small fermion masses that act as regulators of collinear singularities. At…
Møller scattering at NNLO
Pulak Banerjee, Tim Engel, Nicolas Schalch +2
We present a calculation of the full set of next-to-next-to-leading-order QED corrections to unpolarised Møller scattering. This encompasses photonic, leptonic, and non-perturbativ…

W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21
In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…
QED at NNLO with McMule
P. Banerjee, T. Engel, A. Signer +1
McMule is a framework for fully differential higher-order QED calculations of scattering and decay processes involving leptons. It keeps finite lepton masses, which regularises col…
HandyG -- rapid numerical evaluation of generalised polylogarithms in Fortran
L. Naterop, A. Signer, Y. Ulrich
Generalised polylogarithms naturally appear in higher-order calculations of quantum field theories. We present handyG, a Fortran 90 library for the evaluation of such functions, by…
