The Sphaleron in a Magnetic Field and Electroweak Baryogenesis

D. Comelli, D. Grasso, M. Pietroni +1

The presence of a primordial magnetic field in the early universe affects the dynamic of the electroweak phase transition enhancing its strength. This effect may enlarge the window…

On Spontaneous Baryogenesis and Transport Phenomena

D. Comelli, M. Pietroni, A. Riotto

The spontaneous baryogenesis mechanism by Cohen, Kaplan and Nelson is reconsidered taking into account the transport of particles inside the electroweak bubble walls. Using linear…

On the Spontaneous CP Breaking at Finite Temperature in a Nonminimal Supersymmetric Standard Model

D. Comelli, M. Pietroni, A. Riotto

We study the spontaneous CP breaking at finite temperature in the Higgs sector in the Minimal Supersymmetric Standard Model with a gauge singlet. We consider the contribution of th…

Spontaneous Breaking of R parity in the Minimal Supersymmetric Standard Model Revisited

D. Comelli, A. Masiero, M. Pietroni +1

We reconsider the possibility of spontaneous breaking of parity in the Minimal Supersymmetric Standard Model. By a renormalization group analysis we find the parameter space in…

Electromagnetic properties of the neutrinos and the pion radiative decay

D. Grasso, M. Pietroni, A. Riotto

We investigate the implications of neutrino electromagnetic dipole moments for the radiative decay . We show that the dominant new effect comes from the interfer…

Spontaneous CP Violation and Baryogenesis in the Minimal Supersymmetric Standard Model

D. Comelli, M. Pietroni, A. Riotto

We investigate the effects of the spontaneous CP violation at finite temperature in the Minimal Supersymmetric Standard Model on the baryogenesis at the weak scale. After a brief d…
