Higgs mass predictions of public NMSSM spectrum generators / Staub, Florian ; Athron, Peter ; Ellwanger, Ulrich ; Grober, Ramona ; Muhlleitner, Margarete ; Slavich, Pietro ; Voigt, Alexander
The publicly available spectrum generators for the NMSSM often lead to different predictions for the mass of the standard model-like Higgs boson even if using the same renormalization scheme and two-loop accuracy. [...]
