Cosmic Acceleration Data and Bulk-Brane Energy Exchange
C. Bogdanos, S. Nesseris, L. Perivolaropoulos +1
We consider a braneworld model with bulk-brane energy exchange. This allows for crossing of the w=-1 phantom divide line without introducing phantom energy with quantum instabiliti…
Naturally small Dirac neutrino masses in supergravity
Steven Abel, Athanasios Dedes, Kyriakos Tamvakis
We show that Dirac neutrino masses of the right size can arise from the Kahler potential of supergravity. They are proportional to the supersymmetry and the electroweak breaking sc…
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…
Radiative Electroweak symmetry breaking in the MSSM and Low Energy Thresholds
K. Tamvakis
We study Radiative Electroweak Symmetry Breaking in the Minimal Supersymmetric Standard Model (MSSM). We employ the 2-loop Renormalization Group equations for running masses and co…
