Determining Heavy Mass Parameters in Supersymmetric SO(10) Models
Extrapolations of soft scalar mass parameters in supersymmetric theories can be used to explore elements of the physics scenario near the grand unification scale. We investigate the potential of this method in the lepton sector of SO(10) which incorporates right-handed neutrino superfields. The method is exemplified in two models by exploring limits on the precision that can be expected from co...
متن کاملDetermining Supersymmetric Parameters With Dark Matter Experiments
In this article, we explore the ability of direct and indirect dark matter experiments to not only detect neutralino dark matter, but to constrain and measure the parameters of supersymmetry. In particular, we explore the relationship between the phenomenological quantities relevant to dark matter experiments, such as the neutralino annihilation and elastic scattering cross sections, and the un...
متن کاملElectroweak symmetry breaking in supersymmetric models with heavy scalar superpartners
We propose a novel mechanism of electroweak symmetry breaking in supersymmetric models, as the one recently discussed by Birkedal, Chacko and Gaillard, in which the Standard Model Higgs doublet is a pseudo-Goldstone boson of some global symmetry. The Higgs mass parameter is generated at one loop level by two different, moderately fine-tuned sources of the global symmetry breaking. The mechanism...
متن کاملParticle Mass Limits in Minimal and Nonminimal Supersymmetric Models 1
A review of the Higgs and neutralino sector of supersymmetric models is presented. This includes the upper limit on the mass of the lightest Higgs boson in the Minimal Supersymmetric Standard Model, as well as models based on the Standard Model gauge group SU(2)L U(1)Y with extended Higgs sectors. We then discuss the Higgs sector of left-right supersymmetric models, which conserve R-parity as a...
متن کاملThe lightest Higgs mass in supersymmetric models with extra dimensions ∗
In the four-dimensional supersymmetric standard model extended with gauge singlets the lightest Higgs boson mass, M H , has an important contribution proportional to the squared of the superpotential coupling λ of singlets to Higgs fields, λ SH 1 · H 2. The requirement of perturbativity up to the unification scale yields an upper bound on M H ∼ 140 GeV. In extensions to theories with (longitudi...
