Resolving charged hadrons in QED — gauge invariant interpolating operators
Journal of High Energy Physics, 2022 Standard interpolating operators for charged mesons, e.g. J B = b ¯ $$ \overline{b} $$ iγ 5 u for B − , are not gauge invariant in QED and therefore problematic for perturbative methods.

Journal of High Energy Physics, 2021 We analyze in detail the physics potential of an experiment like the one recently proposed by the vIOLETA collaboration: a kilogram-scale Skipper CCD detector deployed 12 meters away from a commercial nuclear reactor core.

QED at NNLO and beyond for precision experiments
Proceedings of 16th International Symposium on Radiative Corrections: Applications of Quantum Field Theory to Phenomenology — PoS(RADCOR2023), 2023 Low-energy experiments allow for some of the most precise measurements in particle physics, such as $g-2$. To make the most of these experiments, theory needs to match the experimental precision. Over the last decade, this meant that even in QED next-to-next-to-leading order calculations (or even more in some cases) became necessary.

THRESHOLD CORRECTIONS IN PRECISION LHC PHYSICS: QED⊗QCD [PDF]
International Journal of Modern Physics A, 2005 With an eye toward LHC processes in which theoretical precisions of 1% are desired, we introduce the theory of the simultaneous YFS resummation of QED and QCD to compute the size of the expected resummed soft radiative threshold effects in precision studies of heavy particle production at the LHC.

Final-state QED multipole radiation in antenna parton showers
Journal of High Energy Physics, 2017 We present a formalism for a fully coherent QED parton shower. The complete multipole structure of photonic radiation is incorporated in a single branching kernel.

Towards muon-electron scattering at NNLO
Journal of High Energy Physics, 2020 The recently proposed MUonE experiment at CERN aims at providing a novel determination of the leading order hadronic contribution to the muon anomalous magnetic moment through the study of elastic muon-electron scattering at relatively small momentum ...

Analytic results for two-loop planar master integrals for Bhabha scattering
Journal of High Energy Physics, 2021 We analytically evaluate the master integrals for the second type of planar contributions to the massive two-loop Bhabha scattering in QED using differential equations with canonical bases.

Status of the BabaYaga event generator [PDF]
EPJ Web of Conferences, 2019 The Monte Carlo event generator BabaYaga has been developed for high precision simulation of QED processes (e+e−→ e+ e− , e+e−→ µ+µ− and e+e−→ γγ) at flavour factories, chiefly for luminometry purposes, with an estimated theoretical accuracy at the 0.1 ...

Journal of High Energy Physics, 2023 In this article, we consider the transverse momentum (q T ) distribution of W and Z bosons produced in hadronic collisions. We combine the q T resummation for QED and QCD radiation including the QED soft emissions from the W boson in the final state.
