LFV in Models with A4 Flavour Symmetry

Luca Merlo

The approximated tri-bimaximal mixing observed in the neutrino oscillations is a particular feature of a class of models characterized by the spontaneously broken horizontal flavou…

B_s mixing phase and lepton flavor violation in supersymmetric SU(5)

Jae-hyeon Park

The connection between B_s mixing phase and lepton flavor violation is studied in SU(5) GUT. The O(1) phase, preferring a non-vanishing squark mixing, generically implies tau -> (e…

B_s mixing phase and lepton flavor violation in supersymmetric SU(5)

Jae-hyeon Park, Masahiro Yamaguchi

We inspect consequences of the latest B_s mixing phase measurements on lepton flavor violation in a supersymmetric SU(5) theory. The O(1) phase, preferring a non-vanishing squark m…

The muon g-2 discrepancy: errors or new physics?

M. Passera, W. J. Marciano, A. Sirlin

After a brief review of the muon g-2 status, we discuss hypothetical errors in the Standard Model prediction that could explain the present discrepancy with the experimental value.…

Successful type I Leptogenesis with SO(10)-inspired mass relations

Pasquale Di Bari, Antonio Riotto

It is well-known that thermal leptogenesis through the decays of the lightest right-handed neutrinos encounters serious difficulties when SO(10)-inspired mass conditions are impose…

Implications of the measurements of B_s - B_s bar mixing on SUSY models

P. Ko, Jae-hyeon Park

We derive constraints on the mass insertion parameters from the recent measurements of B_s - B_s bar mixing, and discuss their implications on SUSY breaking mediation mechanisms an…

Anatomy and Phenomenology of the Lepton Flavor Universality in SUSY Theories

A. Masiero, P. Paradisi, R. Petronzio

High precision electroweak tests, such as deviations from the Standard Model expectations of the Lepton Flavor Universality breaking in K->lnu (with l= e or mu), represent a powerf…

Lepton Flavour Violation in Models with A4 Flavour Symmetry

Ferruccio Feruglio, Claudia Hagedorn, Yin Lin +1

We analyze lepton flavour violating transitions, leptonic magnetic dipole moments (MDMs) and electric dipole moments (EDMs) in a class of models characterized by the flavour symmet…

New aspects of leptogenesis bounds

Steve Blanchet, Pasquale Di Bari

We present a general analysis that reveals new aspects of the leptogenesis bounds on neutrino masses and on the reheat temperature of the Universe. After revisiting a known effect…

Curvature Perturbation from Supersymmetric Flat Directions

Antonio Riotto, Francesco Riva

We show that a contribution to the total curvature perturbation may be due to the presence of flat directions in supersymmetric models. It is generated at the first os- cillation o…

A predictive A4 model, Charged Lepton Hierarchy and Tri-bimaximal Sum Rule

Yin Lin

We propose a novel A4 model in which the Tri-Bimaximal (TB) neutrino mixing and the charged lepton mass hierarchy are reproduced simultaneously. At leading order, the residual symm…

Supersymmetric Leptogenesis and the Gravitino Bound

G. F. Giudice, L. Mether, A. Riotto +1

Supersymmetric thermal leptogenesis with a hierarchical right-handed neutrino mass spectrum requires the mass of the lightest right-handed neutrino to be heavier than about 10^9 Ge…

The muon g-2 and the bounds on the Higgs boson mass

M. Passera, W. J. Marciano, A. Sirlin

After a brief review of the muon g-2 status, we analyze the possibility that the present discrepancy between experiment and the Standard Model (SM) prediction may be due to hypothe…

A SUSY SU(5) Grand Unified Model of Tri-Bimaximal Mixing from A4

Guido Altarelli, Ferruccio Feruglio, Claudia Hagedorn

We discuss a grand unified model based on SUSY SU(5) in extra dimensions and on the flavour group A4xU(1) which, besides reproducing tri-bimaximal mixing for neutrinos with the acc…

On Resumming Inflationary Perturbations beyond One-loop

Antonio Riotto, Martin S. Sloth

It is well known that the correlation functions of a scalar field in a quasi-de Sitter space exhibit at the loop level cumulative infra-red effects proportional to the total number…
