Stabilized NMSSM without Domain Walls
C. Panagiotakopoulos, K. Tamvakis
We reconsider the Next to Minimal Supersymmetric Standard Model (NMSSM) as a natural solution to the -problem and show that both the stability and the cosmological domain wall p…
Suppressing dimension-5 operators in general SU(5) models
M. E. Gomez, J. Rizos, K. Tamvakis
We discuss dimension-5 operators in supersymmetric models containing extra hypercharge 1/3 color-triplets. We derive a general formula relating dimension-5 operator to the color-tr…
Z-Observables and the Effective Weak Mixing Angle in the MSSM
A. Dedes, A. B. Lahanas, K. Tamvakis
We make a comparison of the predicted effective weak mixing angle, the Z-on resonance asymmetries and the W-boson mass to the LEP and SLD data at their present status. We find that…
A Note On R-Parity Violation and Fermion Masses
M. E. Gomez, K. Tamvakis
We consider a class of supersymmetric SU(3)\times SU(2)\times U(1) multihiggs models in which R-parity is violated through bilinear Higgs-lepton interactions. The required, due to…
