B => D(*) transitions in a quark model

Manuela De Vito, Pietro Santorelli

We propose a constituent quark model to evaluate heavy decay constants and form factors relevant for B=>D(*) semileptonic transitions. We show that the model reproduces the scaling…

A Selection Rule for Multiquark Decays

F. Buccella

By assuming SU(6)_cs symmetry for pentaquark decays one finds a selection rule, which strongly reduces the number of states able to decay into a baryon and a meson final state and…

Final state interactions for B => VV charmless decays

Massimo Ladisa, Vincenzo Laporta, Giuseppe Nardulli +1

We estimate final state interactions in the B-meson decays into two light vector mesons by the Regge model. We consider Pomeron exchange and charmed Regge trajectories that can rel…

Ideas for future liquid Argon detectors

A. Ereditato, A. Rubbia

We outline a strategy for future experiments on neutrino and astroparticle physics based on the use, at different detector mass scales (100 ton and 100 kton), of the liquid Argon T…

Leptogenesis in the minimal supersymmetric triplet seesaw model

G. D'Ambrosio, T. Hambye, A. Hektor +2

In the supersymmetric triplet (type-II) seesaw model, in which a single SU(2)_L-triplet couples to leptons, the high-energy neutrino flavour structure can be directly determined fr…

Study of the eightfold degeneracy with a standard -Beam and a Super-Beam facility

A. Donini, E. Fernandez-Martinez, P. Migliozzi +2

The study of the eightfold degeneracy at a neutrino complex that includes a standard -Beam and a Super-Beam facility is presented for the first time in this paper. The scenario…

High energy beta beams without massive detectors

F. Terranova, A. Marotta, P. Migliozzi +1

In this paper, the possibility to exploit a high energy beta beam without massive detectors is discussed. The radioactive ions are boosted up to very high with the neutrino bea…

Neutrino oscillation studies with laser-driven beam dump facilities

S. V. Bulanov, T. Esirkepov, P. Migliozzi +3

A new mechanism is suggested for efficient proton acceleration in the GeV energy range; applications to non-conventional high intensity proton drivers and, hence, to low-energy (10…

Neutrinoless double beta decay in SO(10) inspired seesaw models

F. Buccella, D. Falcone

By requiring the lower limit for the lightest right-handed neutrino mass, obtained in the baryogenesis from leptogenesis scenario, and a Dirac neutrino mass matrix similar to the u…
