Generic two-loop results for trilinear and quartic scalar self-interactions
Henning Bahl, Johannes Braathen, Martin Gabelmann +1
Reconstructing the shape of the Higgs potential realised in Nature is a central part of the physics programme at the LHC and future colliders. In this context, accurate theoretical…

Improved Thermal Resummation for Multi-Field Potentials
Henning Bahl, Marcela Carena, Aurora Ireland +1
The resummation of large thermal corrections to the effective potential is mandatory for the accurate prediction of phase transitions. We discuss the accuracy of different prescrip…
