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…
Protecting the Baryon Asymmetry in Theories with R-parity Violation
Sacha Davidson, Ralf Hempfling
We propose a mechanism for hiding the primordial baryon asymmetry from interactions that could wash it out. It requires the introduction of a baryon number carrying singlet which i…
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…
The Next-to-Minimal Coleman-Weinberg Model
Ralf Hempfling
In the standard model (SM) the condition that the Higgs mass parameter vanishes is stable under radiative corrections and yields a theory that can be renormalized using dimensional…
