A note on momentum subtraction schemes for quark bilinears and semileptonic operators

P. A. Boyle, M. Bruno, M. Gorbahn +4

In this work we examine a family of regularization invariant (RI) symmetric momentum (SMOM) schemes for semi-leptonic operators. By working with chirally symmetric and massless QCD…

Renormalisation and invariants for two U(1)s

Sacha Davidson, Martin Gorbahn

We revisit the renormalisation of models with two U(1) gauge symmetries, in a formulation with non-canonical gauge kinetic terms which is covariant under field reparametrisations a…

Linking Leptogenesis and Asymmetric Dark Matter: A Testable Framework for Neutrino Mass and the Matter-Antimatter Asymmetry

Henry G. F. McKenna, Juri Smirnov, Martin Gorbahn

We investigate a minimal extension of the Leptogenesis framework that simultaneously explains the observed baryon asymmetry and dark matter (DM) abundance through the decay of a he…

Beyond Leading Logarithms in : The Semileptonic Weak Hamiltonian at

Francesco Moretti, Martin Gorbahn, Sebastian Jaeger

We present the first next-to-leading-logarithmic QCD analysis of the electromagnetic corrections to the semileptonic weak Hamiltonian, including the mixed c…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

Proposal of the KOTO II experiment

Jung Keun Ahn, Antonella Antonelli, Giuseppina Anzivino +79

The KOTO II experiment is proposed to measure the branching ratio of the decay at J-PARC. With a beamline to extract long-lived neutral kaons at 5 degrees from a…
