Thermal Background Corrections to the Neutrino Electromagnetic Vertex in Models with Charged Scalar Bosons

Antonio Riotto

We calculate the correction to the neutrino electromagnetic vertex due to background of electrons in a large class of models, as the supersymmetric model with explicit breaking of…

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 $R$ parity in the Minimal Supersymmetric Standard Model. By a renormalization group analysis we find the parameter space in…

Renormalization Group Equations for Seesaw Neutrino Masses

Piotr H. Chankowski, Zbigniew Pluciennik

RGEs for coefficients of dim-5 operators giving rise to neutrino masses in the seesaw mechanism are written down in the SM, 2HDM and MSSM, and solved numerically. RG evolution of t…

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 $π \to e ν γ$ . We show that the dominant new effect comes from the interfer…

Hadronic Transitions among Quarkonium States in a Soft-Exchange-Approximation. Chiral Breaking and Spin Symmetry Breaking Processes

R. Casalbuoni, A. Deandrea, N. Di Bartolomeo +3

Although no asymptotic heavy quark spin symmetry, and even more no flavor symmetry, are expected for systems such as quarkonium, a numerical discussion shows that for some processe…

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…

Gauge Invariance and Anomalous Dimensions of a Light-Cone Wilson Loop in Light-Like Axial Gauge

A. Bassetto, I. A. Korchemskaya, G. P. Korchemsky +1

Complete two-loop calculation of a dimensionally regularized Wilson loop with light-like segments is performed in the light-like axial gauge with the Mandelstam-Leibbrandt prescrip…

Complete On-Shell Renormalization Scheme for the Minimal Supersymmetric Higgs Sector

P. Chankowski, S. Pokorski, J. Rosiek

Systematic on-shell renormalization programme is carried out for the Higgs and gauge boson sectors of the Minimal Supersymmetric Standard Model. Complete 1-loop results for the 2-…

Current Algebra Approach to Heavy Top Effects in $Z \to b + b ˉ$

Giuseppe Degrassi

The $O (α m_{t}^{2} / m_{w}^{2})$ and $O (α α_{s} m_{t}^{2} / m_{w}^{2})$ corrections to the partial decay width $Γ (Z \to b + b ˉ)$ are computed using the current algebra formulation of radiativ…

Spontaneous CP Violation in the Minimal Supersymmetric Standard Model at Finite Temperature

D. Comelli, M. Pietroni

We show that in the Minimal Supersymmetric Standard Model one--loop effects at finite temperature may lead to a spontaneous breaking of CP invariance in the scalar sector. Requirin…
