Stability of the Higgs Potential in the Standard Model and Beyond
Tom Steudtner
The question of stability of the Higgs potential in the Standard Model is revisited employing advanced theoretical precision and recent experimental results. We show that the top m…

Revisiting the Theory in Three Dimensions at Large
Sandra KvedaraitÄ, Tom Steudtner, Max Uetrecht
We investigate the --symmetric theory in three spacetime dimensions using dimensional regularisation and minimal subtraction. The predictions of other methods are scru…

Quantum multicriticality and emergent symmetry in Dirac systems with two order parameters at three-loop order
Max Uetrecht, Igor F. Herbut, Michael M. Scherer +2
Two-dimensional materials with interacting Dirac excitations can host quantum multicritical behavior near the phase boundaries of the semimetallic and two-ordered phases. We study…
