Squark contributions to Higgs Boson masses in the next-to-minimal supersymmetric standard model
Squark contributions to Higgs Boson masses in the next-to-minimal supersymmetric standard model
Within the context of an effective potential formalism we calculate the contribution to Higgs boson masses in the next-to-minimal supersymmetric standard model from squark loops. We then supplement a previously performed renormalisation group analysis of the Higgs sector of this model with these results in order to determine the shift in the bound on the lightest CP-even Higgs boson mass as a result of squark effects. The improved bound on the lightest neutral CP-even Higgs boson mass, including squark contributions, is mh ⩽ 146 (139, 149) GeV for mt = 90 (140, 190) GeV. For mt = 190 GeV squark effects contribute 23 GeV to the bound, with smaller contributions for small mt values.

Abstract
Within the context of an effective potential formalism we calculate the contribution to Higgs boson masses in the next-to-minimal supersymmetric standard model from squark loops. We then supplement a previously performed renormalisation group analysis of the Higgs sector of this model with these results in order to determine the shift in the bound on the lightest CP-even Higgs boson mass as a result of squark effects. The improved bound on the lightest neutral CP-even Higgs boson mass, including squark contributions, is mh ⩽ 146 (139, 149) GeV for mt = 90 (140, 190) GeV. For mt = 190 GeV squark effects contribute 23 GeV to the bound, with smaller contributions for small mt values.
