Biased discrete symmetry and domain wall problem

G. Dvali, Z. Tavartkiladze, J. Nanobashvili

We reconsider a cosmological evolution of domain walls produced by spontaneous breaking of an approxime discrete symmetry. We show, that domain walls may never collapse even if the…

Light thresholds in Grand Unified Theories

R. Barbieri, P. Ciafaloni, A. Strumia

In a generic Grand Unified Theory with a relatively small dispersion of the spectrum around the -boson and the unification masses, a connection is established, exact at one loop…

Signals For Supersymmetric Unification

R. Barbieri, L. J. Hall

Using the Yukawa couplings of the minimal supersymmetric SU(5) model, the rates for , conversion and are computed. For a selectron mass of 100 GeV, and…

Semiglobal Alice Strings

G. Dvali, G. Senjanovi'{c}

We show that in certain theories with topologically trivial quotient space of spontaneously broken gauge symmetry there can exist topologically stable strings that carry nonabelian…

Fermion masses and mixings in a flavour symmetric GUT

Riccardo Barbieri, Gia Dvali, Alessandro Strumia

We describe a supersymmetric Grand Unified Theory based on the gauge group $\SU(5)^3$, or $\SO(10)^3$, invariant under the interchange of any~SU(5), or~SO(10), with each family mul…

Large Scale Structure and Supersymmetric Inflation without Fine Tuning

G. Dvali, Q. Shafi, R. Schaefer

We explore constraints on the spectral index of density fluctuations and the neutrino energy density fraction , employing data from a variety of large scale observatio…

Flavour in supersymmetric Grand Unification: a democratic approach

R. Barbieri, Z. Berezhiani, G. Dvali +2

We consider the flavour problem in a supersymmetric Grand Unified theory with gauged SU(6) group, where the Higgs doublets are understood as pseudo-Goldstone bosons of a larger $\S…

QCD corrections to electroweak processes in an unconventional scheme: application to the b -> s gamma decay

Giancarlo Cella, Giuseppe Curci, Giulia Ricciardi +1

In this work we give a detailed description of a method for the calculation of QCD corrections to electroweak processes in dimensional regularization that does not require any defi…

Gauge Hierarchy, Planck Scale Corrections And The Origin of GUT Scale In Supersymmetric

G. Dvali, Q. Shafi

Within a supersymmetric unified framework we explore the resolution of the gauge hierarchy problem taking account of the non-renormalizable terms in the superpotential. For $[SU(3)…

Strings versus supersymmetric GUTs: can they be reconciled?

R. Barbieri, G. Dvali, A. Strumia

We describe a class of supersymmetric unified models with the following properties: i) the full breaking of the gauge group is achieved by Higgs fields in the fundamental represent…

Topologically Stable Z - Strings in the Supersymmetric Standard Model

G. Dvali, Goran Senjanovi{ć}

We show that the minimal supergravity extension of the standard model automatically contains topologically stable electroweak strings if the hidden sector is invariant under the ex…

The b -> s gamma decay revisited

G. Cella, G. Curci, G. Ricciardi +1

In this work we compute the leading logarithmic corrections to the b -> s gamma decay in a dimensional scheme which does not require any definition of the gamma5 matrix. The scheme…

The Top Mass Upper Bound and Electroweak Radiative Corrections

F. Caravaglios

We investigated the possibility of introducing sizeable negative corrections to the () parameter without affecting . We have found that a p…
