Two-Loop Vertices in Quantum Field Theory: Infrared Convergent Scalar Configurations

A. Ferroglia, G. Passarino, M. Passera +1

A comprehensive study is performed of general massive, scalar, two-loop Feynman diagrams with three external legs. Algorithms for their numerical evaluation are introduced and disc…

Bulk fields with brane terms

F. del Aguila, M. Perez-Victoria, J. Santiago

In theories with branes, bulk fields get in general divergent corrections localized on these defects. Hence, the corresponding brane terms are renormalized and should be included i…

Towards a complete theory of thermal leptogenesis in the SM and MSSM

G. F. Giudice, A. Notari, M. Raidal +2

We perform a thorough study of thermal leptogenesis adding finite temperature effects, RGE corrections, scatterings involving gauge bosons and by properly avoiding overcounting on-…

On Non-Gaussianity in the Curvaton Scenario

N. Bartolo, S. Matarrese, A. Riotto

Since a positive future detection of non-linearity in the cosmic microwave background anisotropy pattern might allow to descriminate among different mechanisms giving rise to cosmo…

On the reheating stage after inflation

Edward W. Kolb, Alessio Notari, Antonio Riotto

We point out that inflaton decay products acquire plasma masses during the reheating phase following inflation. The plasma masses may render inflaton decay kinematicaly forbidden,…

Grand Unification of Quark and Lepton FCNCs

M. Ciuchini, A. Masiero, L. Silvestrini +2

In the context of Supersymmetric Grand Unified theories with soft breaking terms arising at the Planck scale, it is generally possible to link flavor changing neutral current and C…

Minimal Theoretical Uncertainties in Inflationary Predictions

D. J. H. Chung, A. Notari, A. Riotto

During inflation, primordial energy density fluctuations are created from approximate de Sitter vacuum quantum fluctuations redshifted out of the horizon after which they are froze…

Supersymmetry breaking with quasi-localized fields in orbifold field theories

G. V. Gersdorff, L. Pilo, M. Quiros +2

We study the Scherk-Schwarz supersymmetry breaking in five-dimensional orbifold theories with five-dimensional fields which are not strictly localized on the boundaries (quasi-loca…

WMAPping inflationary physics

William H. Kinney, Edward W. Kolb, Alessandro Melchiorri +1

We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) data set, and from a combination of the W…

Fermion Generations, Masses and Mixing Angles from Extra Dimensions

Carla Biggio, Ferruccio Feruglio, Isabella Masina +1

We discuss a toy model in six dimensions that predicts two fermion generations, natural mass hierarchy and intergenerational mixing. Matter is described by vector-like six dimensio…

Lepton Flavour Violating Decays of Supersymmetric Higgs Bosons

Andrea Brignole, Anna Rossi

We compute the lepton flavour violating couplings of Higgs bosons in the Minimal Supersymmetric Standard Model, and show that they can induce the decays (h,H,A) --> mu tau at non-n…

The Curvaton as a Pseudo-Nambu-Goldstone Boson

K. Dimopoulos, D. H. Lyth, A. Notari +1

The field responsible for the cosmological curvature perturbations generated during a stage of primordial inflation might be the ``curvaton'', a field different from the inflaton f…

The Pomeron In Exclusive Vector Meson Production

R. Fiore, L. L. Jenkovszky, F. Paccanoni +1

An earlier developed model for vector meson photoproduction, based on a dipole Pomeron exchange, is extended to electroproduction. Universality of the non linear Pomeron trajectory…

Dark Energy and Dark Matter

D. Comelli, M. Pietroni, A. Riotto

It is a puzzle why the densities of dark matter and dark energy are nearly equal today when they scale so differently during the expansion of the universe. This conundrum may be so…

Ultra-high energy neutrino-nucleon interactions

R. Fiore, L. L. Jenkovszky, A. Kotikov +3

Ultra-high energy ( GeV) neutrino-nucleon total cross sections are estimated from a soft non-perturbative model complemented by an approximate QCD evolution, ex…

Quintessential Enhancement of Dark Matter Abundance

F. Rosati

The presence of a dynamical scalar field in the early universe could significantly affect the `freeze-out' time of particle species. In particular, it was recently shown that an en…

Low-scale supersymmetry breaking: effective description, electroweak breaking and phenomenology

A. Brignole, J. A. Casas, J. R. Espinosa +1

We consider supersymmetric scenarios in which the scale of SUSY breaking is low, sqrt{F}=O(TeV). Instead of studying specific models of this type, e.g. those with extra dimensions…
