Analytic model of Regge trajectories

R. Fiore, L. L. Jenkovszky, V. Magas +2

A model for a Regge trajectory compatible with the threshold behavior required by unitarity and asymptotics in agreement with analyticity constraints is given in explicit form. The…

The flavor of neutrinos in muon decays at a neutrino factory and the LSND puzzle

A. Bueno, M. Campanelli, M. Laveder +2

The accurate prediction of the neutrino beam produced in muon decays and the absence of opposite helicity contamination for a particular neutrino flavor make a future neutrino fact…

Finite sum of gluon ladders and high energy cross sections

R. Fiore, L. L. Jenkovszky, E. A. Kuraev +3

A model for the Pomeron at is suggested. It is based on the idea of a finite sum of ladder diagrams in QCD. Accordingly, the number of -channel gluon rungs and correspondi…

Large nu_mu->nu_tau and nu_e->nu_tau transitions in short-baseline experiments?

C. Giunti, M. Laveder

Considering four-neutrino schemes of type 3+1, we identify four small regions of the neutrino mixing parameter space compatible with all data. Assuming a small mixing between the s…

Eigenvalues of the QCD Dirac operator at finite temperature and density

Elmar Bittner, Maria-Paola Lombardo, Harald Markum +1

We investigate the eigenvalue spectrum of the staggered Dirac matrix in two-color QCD at nonzero temperature and at baryon density when the eigenvalues become complex. The quasi-ze…

B -> X_s gamma in supersymmetry: large contributions beyond the leading order

G. Degrassi, P. Gambino, G. F. Giudice

We discuss possible large contributions to B -> X_s gamma, which can occur at the next-to-leading order in supersymmetric models. They can originate from terms enhanced by tan(beta…

Boltzmann Suppression of Interacting Heavy Particles

Patrizia Bucci, Massimo Pietroni

Matsumoto and Yoshimura have recently argued that the number density of heavy particles in a thermal bath is not necessarily Boltzmann-suppressed for T << M, as power law correctio…

Constraints on R-Parity violating stop couplings from flavor physics

Pietro Slavich

We perform a critical reassessment of the constraints on the R-parity and baryon number violating (s)top couplings coming from flavor physics. In particular, we study K0-K0bar mixi…

From Minimal to Realistic Supersymmetric SU(5) Grand Unification

Guido Altarelli, Ferruccio Feruglio, Isabella Masina

We construct and discuss a "realistic" example of SUSY SU(5) GUT model, with an additional U(1) flavour symmetry, that is not plagued by the need of large fine tunings, like those…

Signatures of massive sgoldstinos at hadron colliders

Elena Perazzi, Giovanni Ridolfi, Fabio Zwirner

In supersymmetric extensions of the Standard Model with a very light gravitino, the effective theory at the weak scale should contain not only the goldstino, but also its supersymm…

Indirect constraints on R-parity violating stop couplings

Pietro Slavich

It was recently claimed that single stop production at the Tevatron, occurring via R-parity (and baryon number) violating couplings, could lead to observable signals. In this talk…

Predictive Grand Unified Textures for Quark and Neutrino Masses and Mixings

Zurab Berezhiani, Anna Rossi

We propose new textures for the fermion Yukawa matrices which are generalizations of the so-called Stech ansatz. We discuss how these textures can be realized in supersymmetric gra…

Primordial Magnetic Fields and Electroweak Baryogenesis

Dario Grasso

In this contribution we will shortly review the main mechanism through which primordial magnetic fields may affect the electroweak baryogenesis. It is shown that although strong ma…

Signatures of massive sgoldstinos at e+e- colliders

Elena Perazzi, Giovanni Ridolfi, Fabio Zwirner

In supersymmetric extensions of the Standard Model with a very light gravitino, the effective theory at the weak scale should contain not only the goldstino G, but also its supersy…
