Running of neutrino mass parameters in the Zee model

Michael A. Schmidt, James Vandeleur

We analyse the size of quantum corrections in the Zee model using effective field theory techniques. We derive the relevant 1-loop matching conditions and use them together with th…

Constraints on invisible $B^{+} \to K^{+} X$ decays from the Belle II $B^{+} \to K^{+} I^½ I^ˉ ½$ measurement

Lorenz GÃ¤rtner, Nikolai Krug, Thomas Kuhr +3

Belle II measurement of the branching fraction for $B^{+} \to K^{+} I^½ I^ˉ ½$ shows a $2.7 I ¨ $ excess over the Standard Model prediction and motivates new-physics explanations such…

Neutrino Theory in the Precision Era

Asmaa Abada, Gabriela Barenboim, Toni BertÃ³lez-MartÃnez +76

This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
