Phase structure and Higgs boson mass in a Higgs-Yukawa model with a dimension-6 operator

David Y. -J. Chu, Karl Jansen, Bastian Knippschild +3

We investigate the impact of a ${\lambda }_6{\phi }^6$ term included in a chirally invariant lattice Higgs-Yukawa model. Such a term could emerge from BSM physics at some larger energy scale. We…
