Effective Field Theory Perspective On King Non-linearity

Benoît Assi, Sam Carey, Sebastian Jäger +4

Precision spectroscopic measurements of isotope shifts have recently reached a high level of accuracy. Tests of King non-linearity (NL) along isotope chains have been proposed as a…

Semileptonic weak Hamiltonian to in momentum-space subtraction schemes

M. Gorbahn, S. Jäger, F. Moretti +1

The CKM unitarity precision test of the Standard Model requires a systematic treatment of electromagnetic and strong corrections for semi-leptonic decays. Electromagnetic correctio…

Probing B-Anomalies via Dimuon Tails at a Future Collider

Bradley Garland, Sebastian Jäger, Charanjit K. Khosa +1

We investigate the sensitivity of future proton-proton colliders to a contact interaction of the form as indicated by the long-standing r…

Charming New -Physics

S. Jäger, M. Kirk, A. Lenz +1

We give a comprehensive account of the flavour physics of Beyond-Standard-Model (BSM) effects in transitions, considering the full set of 20 four-quark operator…

Towards the discovery of new physics with lepton-universality ratios of decays

Li-Sheng Geng, Benjamín Grinstein, Sebastian Jäger +3

Tests of lepton-universality as rate ratios in transitions can be predicted very accurately in the Standard Model. The deficits with respect to expectations repor…

Charming new physics in rare B-decays and mixing?

Sebastian Jäger, Matthew Kirk, Alexander Lenz +1

We conduct a systematic study of the impact of new physics in quark-level transitions on -physics, in particular rare -decays and -meson lifetime obser…
