b -> s Transitions: A New Frontier for Indirect SUSY Searches

M. Ciuchini, E. Franco, A. Masiero +1

The present unitarity triangle fit, whose essential input is represented by the s to d and b to d transition processes, fully agrees with the SM. However, most of the phenomena inv…

Twisted Moduli and Supersymmetry Breaking

S. F. King, D. A. J. Rayner

We discuss how localized twisted moduli in type I string theory can provide a string realization of brane world supersymmetry breaking models.

Quintessence and the Underlying Particle Physics Theory

D. J. H. Chung, L. L. Everett, A. Riotto

At present we know nothing about the nature of the dark energy accounting for about 70% of the energy density of the Universe. One possibility is that the dark energy is provided b…

Models of Neutrino Masses: Anarchy versus Hierarchy

Guido Altarelli, Ferruccio Feruglio, Isabella Masina

We present a quantitative study of the ability of models with different levels of hierarchy to reproduce the solar neutrino solutions, in particular the LA solution. As a flexible…

Inflation and the Theory of Cosmological Perturbations

Antonio Riotto

These lectures provide a pedagogical introduction to inflation and the theory of cosmological perturbations generated during inflation which are thought to be the origin of structu…

All-Purpose Numerical Evaluation of One-Loop Multi-Leg Feynman Diagrams

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

A detailed investigation is presented of a set of algorithms which form the basis for a fast and reliable numerical integration of one-loop multi-leg (up to six) Feynman diagrams,…

Seesaw and Lepton Flavour Violation in SUSY SO(10)

Antonio Masiero, Sudhir K. Vempati, Oscar Vives

That and are sensitive probes of SUSY models with a see-saw mechanism is a well accepted fact. Here we propose a `top-down' approach in a general SUSY SO(10)…

Supersymmetric Dark Matter and the Reheating Temperature of the Universe

N. Fornengo, A. Riotto, S. Scopel

Since the thermal history of the Universe is unknown before the epoch of primordial nucleosynthesis, the largest temperature of the radiation dominated phase (the reheating tempera…

Supersymmetric Seesaw without Singlet Neutrinos: Neutrino Masses and Lepton-Flavour Violation

Anna Rossi

We consider the supersymmetric seesaw mechanism induced by the exchange of heavy SU(2)_W triplet states, rather than `right-handed' neutrino singlets, to generate neutrino masses.…

Chiral order and fluctuations in multi-flavour QCD

S. Descotes-Genon, L. Girlanda, J. Stern

Multi-flavour (N_f>=3) Chiral Perturbation Theory (ChPT) may exhibit instabilities due to vacuum fluctuations of sea q-bar q pairs. Keeping the fluctuations small would require a v…

Transdimensional physics and inflation

G. F. Giudice, E. W. Kolb, J. Lesgourgues +1

Within the framework of a five-dimensional brane world with a stabilized radion, we compute the cosmological perturbations generated during inflation and show that the perturbation…

Theoretical Models of Neutrino Masses and Mixings

Guido Altarelli, Ferruccio Feruglio

We review theoretical ideas, problems and implications of different models for neutrino masses and mixing angles. We give a general discussion of schemes with three or more light n…

On the two-loop sbottom corrections to the neutral Higgs boson masses in the MSSM

A. Brignole, G. Degrassi, P. Slavich +1

We compute the O(ab*as) two-loop corrections to the neutral Higgs boson masses in the Minimal Supersymmetric Standard Model, using the effective potential approach. Such correction…

Neutrino mixing and large CP violation in B physics

Darwin Chang, Antonio Masiero, Hitoshi Murayama

We show that in see-saw models of neutrino mass a la SUSY SO(10), the observed large mixing in atmospheric neutrinos naturally leads to large b-s transitions. If the associated new…

Simple Formulae for Sin^2 theta_eff^lept, M_W, Gamma_l, and their Physical Applications

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

The calculation of the partial widths of the Z boson in the effective scheme is discussed. Simple formulae for Sin^2 theta_eff^lept, M_W, and Gamma_l in the on-shell, MS, and effec…

Brane Worlds and the Cosmic Coincidence Problem

Massimo Pietroni

Brane world models with `large' extra dimensions with radii in the r_l ~ 0.01- 0.1 mm range and smaller ones at r_s < (1 TeV)^(-1) have the potential to solve the cosmic coincidenc…

Elastic Scattering of Neutrinos off Polarized Electrons

P. Minkowski, M. Passera

We calculate the cross sections for elastic nu_l + e -> nu_l + e and antinu_l + e -> antinu_l + e scattering (l=e, mu or tau) in the Born approximation and with exactly fixed polar…

Pomeron exchange and t-dependence of the scattering amplitude

F. Paccanoni

Constraints on the t-dependence of the hadronic scattering amplitude at asymptotic energies are derived by considering the exchange of the Pomeron, as a Regge pole, between off-she…

Neutrino oscillations and signals in beta and 0nu2beta experiments

Ferruccio Feruglio, Alessandro Strumia, Francesco Vissani

Assuming Majorana neutrinos, we infer from oscillation data the expected values of the parameters m_{nu_e} and m_{ee} probed by beta and 0nu2beta-decay experiments. If neutrinos ha…
