Title: Effective Potential and Vacuum Stability in the Litim-Sannino Model
(Submitted on 26 Feb 2024 (v1), last revised 24 Apr 2024 (this version, v2))
Abstract: We revisit the scalar potential in the Litim-Sannino model. We compute for the first time the full quantum corrections to the classical potential and show that they significantly ameliorate the stability analysis at the UV fixed point. The quantum effective potential is computed at two-loop order and the numerical precision is further improved using resummations and parameter optimisations. As a result, we find a consistent widening of the UV conformal window across various approximations.
