Non-collapsing renormalized QRPA with proton-neutron pairing for neutrinoless double beta decay
F. Simkovic, J. Schwieger, M. Veselsky +2
Using the renormalized quasiparticle random phase approximation (RQRPA), we calculate the light neutrino mass mediated mode of neutrinoless double beta decay of Ge76, Mo100, Te128…
Neutrinoless Double Beta Decay within QRPA with Proton-Neutron Pairing
G. Pantis, F. Simkovic, J. D. Vergados +1
We have investigated the role of proton-neutron pairing in the context of the Quasiparticle Random Phase approximation formalism. This way the neutrinoless double beta decay matrix…
The μ- term in Effective Supergravity Theories
G. K. Leontaris, N. D. Tracas
The Higgs mixing term coefficient is calculated in the scalar potential in supergravity theories with string origin, in a model independent approach. A general low energy…
Threshold effects and radiative electroweak symmetry breaking in extensions of the MSSM
A. Dedes, A. B. Lahanas, J. Rizos +1
We make a complete analysis of radiative symmetry breaking in the MSSM and its extensions including low- and high-energy threshold effects in the framework of the two-loop…
Yukawa Textures in String Unified Models With SU(4)xO(4) Symmetry
B. C. Allanach, S. F. King, G. K. Leontaris +1
We discuss the origin of Yukawa textures in the string-inspired and string derived models based on the gauge group SU(4)xSU(2)_LxSU(2)_R supplemented by a U(1)_X gauged family symm…
Duality Constraints on Supersymmetric Unified Models and Radiative Symmetry Breaking
G. K. Leontaris, N. D. Tracas
Motivated from unified models with string origin, we analyse the constraints from duality invariance on effective supergravity models with an intermediate gauge symmetry. Requiring…
