Unitarity Cuts, t-channel Divergences and the KLN Theorem for Unstable Particles
Marko Beocanin, Michael A. Schmidt
Many phenomenological calculations involving massless or unstable particles suffer from divergences as mediating particles go on-shell. One way to deal with these divergences is vi…
Complementarity of TRISTAN and Belle II in searches for charged-lepton flavour violation
Gabriela Lichtenstein, Michael A. Schmidt, German Valencia +1
We analyse the potential of the proposed and collider TRISTAN to complement the searches for charged-lepton flavour-violation (CLFV) that can be carried out…
Probing general models with non-universal lepton charges at FASER/FASER2, COHERENT and long-baseline oscillation experiments
Tobias Felkl, Tong Li, Jiajun Liao +1
The general anomaly-free models allow non-universal lepton charges. We explore the sensitivities of FASER/FASER2, COHERENT and DUNE/T2HK precision experiments to the new ga…
Complementarity of and for searches of GeV-scale Higgs-like scalars
Maksym Ovchynnikov, Michael A. Schmidt, Thomas Schwetz
The rare decays and provide the strongest constraints on the mixing of a light scalar with the Higgs boson for GeV-scale masses. The con…
Riding the Seesaw: What Higgsstrahlung May Reveal about Massive Neutrinos
Tobias Felkl, Adam Lackner, Michael A. Schmidt
We investigate if the projected high-precision measurements of the cross section of the Higgsstrahlung process at a future electron-positron collider can be utilis…
Indirect constraints on lepton-flavour-violating quarkonium decays
Lorenzo Calibbi, Tong Li, Xabier Marcano +1
Within an effective-field-theory framework, we present a model-independent analysis of the potential of discovering new physics by searching for lepton flavour violation in heavy q…
