Weak Electric Dipole Moments of Heavy Fermions in the MSSM
A minimal supersymmetric version of the Standard Model with complex parameters allows contributions to the weak–electric dipole moments of fermions at the one–loop level. Assuming generation–diagonal trilinear soft–susy–breaking terms and the usual GUT constraint, a set of CP–violating physical phases can be introduced. In this paper the general expressions for the one–loop contribution to the ...
متن کاملOne-loop Weak Dipole Form Factors and Weak Dipole Moments of Heavy Fermions
The one–loop weak–magnetic and weak–electric dipole form factors of heavy fermions in a generic model are derived. Numerical predictions for the τ lepton and b quark Weak Anomalous Magnetic and Electric Dipole Moments (AWMDM and WEDM) in the SM and MSSM are reviewed. The MSSM contribution to the τ (b) AWMDM could be, in the high tan β scenario, four (thirty) times larger than the Electroweak SM...
متن کاملWeak antilocalization of ultrarelativistic fermions
The Letter discusses the Berry phase influence on the weak localization phenomenon at the adiabatic backscattering of ultrarelativistic particles in a random medium. We demonstrate that bosons that pass along a certain closed path in opposite directions come back always in phase (an example: the backscattering enhancement of electromagnetic waves), whereas fermions come exactly in antiphase. Th...
متن کاملSpontaneously Broken Gauge Theories of Weak Interactions and Heavy Leptons
Branching ratios and production cross sections are calculated for the heavy leptons which occur in a class of spontaneously broken gauge theories of weak interactions. Several examples of such theories are constructed. (Submitted to Phys. Rev. ) * Supported by the U. S. Atomic Energy Commission. t Address after August 15, 1972: CERN, Geneva, Switzerland.
متن کاملDifferent Aspects of Ultra-weak Photon Emissions: A Review Article
All biological samples emit ultra-low intensity light without any external stimulation. Recently, scientific communities have paid particular attention to this phenomenon, known as ultra-weak photon emission (UPE). UPE has been introduced in the literature as an alternative for biophoton, low-level chemiluminescence and ultra-weak bioluminescence, while it differs from ordinary bioluminescence,...
