On the Theory Error
Saad Nabeebaccus, Roman Zwicky
To quantify the theory error on , essentially means to quantify the uncertainty due to QED corrections since the latter breaks lepton flavour universality through the lepton m…
Resolving Charged Hadrons in QED -- Gauge Invariant Interpolating Operators
Saad Nabeebaccus, Roman Zwicky
Standard interpolating operators for charged mesons, e.g. for , are not gauge invariant in QED and therefore problematic for perturbative methods. We…
Notes on QED Corrections in Weak Decays
Roman Zwicky
In these lecture notes the basics of QED corrections to hadronic decays are reviewed with special emphasis on conceptual (e.g. counting and tracking of infrared sensitive logs) rat…
QED in LFU ratios: Theory versus Experiment, a Monte Carlo Study
Gino Isidori, Davide Lancerini, Saad Nabeebaccus +1
Using analytic results obtained in a meson effective theory, that includes all infrared sensitive logs, we build a dedicated Monte Carlo framework to describe QED corrections in $\…
