SUSY without R-parity: symmetry breaking and LSP phenomenology
Ralf Hempfling
We have studied the predictions for the LSP decay within the framework of a radiatively broken unified supergravity model without R-parity. Assuming that Higgs/slepton mixing is th…
Neutrino properties and SUSY without -parity
Ralf Hempfling
In supersymmetric models without -parity neutrinos naturally become massive and mix with each other. We explore the predictions of a very restricted model with only three free p…
Approximating the radiatively corrected Higgs mass in the Minimal Supersymmetric Model
Howard E. Haber, Ralf Hempfling, Andre H. Hoang
To obtain the most accurate predictions for the Higgs masses in the minimal supersymmetric model (MSSM), one should compute the full set of one-loop radiative corrections, resum th…
Gauge boson pair production at LEP and NLC
Ralf Hempfling
We compute the dominant one-loop radiative corrections to the cross-section for ) in the MSSM. We find that the genuine vertex…
Supersymmetry at Present and Future Colliders
Ralf Hempfling
The theoretical expectations for the supersymmetric particle spectrum is reviewed and a brief overview on present constraints on supersymmetric models from collider experiments is…
Gauge Coupling Unification in General SUSY Models
Ralf Hempfling
We study the effects of additional fields on the unification of gauge couplings in supersymmetric models. We find that the effects are quite constrained by the requirement of SU(5)…
