Conceptual design of a scalable multi-kton superconducting magnetized liquid Argon TPC

A. Ereditato, A. Rubbia

We discuss the possibility of new generation neutrino and astroparticle physics experiments exploiting a superconducting magnetized liquid Argon Time Projection Chamber (LAr TPC).…

Threshold resummed spectra in B -> Xu l nu decays in NLO (II)

Ugo Aglietti, Giulia Ricciardi, Giancarlo Ferrera

We resum to next-to-leading order the distribution in the ratio of the invariant hadron mass mX to the total hadron energy EX and the distribution in mX in the semileptonic decays…

The liquid Argon TPC: a powerful detector for future neutrino experiments and proton decay searches

A. Ereditato, A. Rubbia

We discuss the possibility of new generation neutrino and astroparticle physics experiments exploiting the liquid Argon Time Projection Chamber (LAr TPC) technique, following a gra…

Threshold resummed spectra in B ->Xu l nu decays in NLO (III)

Ugo Aglietti, Giulia Ricciardi, Giancarlo Ferrera

We resum to next-to-leading order (NLO) the distribution in the light-cone momentum p+ = EX - |pX| and the spectrum in the electron energy, in the semileptonic decays B-> Xu l nu,…

Role of final state interactions in the B meson decay into two pions

Aldo Deandrea, Massimo Ladisa, Vincenzo Laporta +2

We estimate final state interactions in the B-meson decays into two pions by the Regge model. We consider Pomeron exchange and the leading Regge trajectories that can relate interm…

Baryon asymmetry in the Universe resulting from Lorentz violation

E. Di Grezia, S. Esposito, G. Salesi

We analyze the phenomenological consequences of a Lorentz violating energy-momentum dispersion relation in order to give a simple explanation for the baryon asymmetry in the Univer…

Threshold Resummed Spectra in B -> Xu l nu Decays in NLO (I)

Ugo Aglietti, Giulia Ricciardi, Giancarlo Ferrera

We evaluate thresholds resummed spectra in B -> Xu l nu decays in next-to-leading order. We present results for the distribution in E_X and in m_X^2/E_X^2, for the distribution in…

Next-to-leading order corrections to Wt production and decay

John Campbell, Francesco Tramontano

We present the results of a next-to-leading order calculation of Wt production, including the decays of both the top quark and the W boson. The effects of radiation in the decay of…

Relic neutrino decoupling including flavour oscillations

Gianpiero Mangano, Gennaro Miele, Sergio Pastor +3

In the early universe, neutrinos are slightly coupled when electron-positron pairs annihilate transferring their entropy to photons. This process originates non-thermal distortions…

Laboratory bounds on Lorentz symmetry violation in low energy neutrino physics

E. Di Grezia, S. Esposito, G. Salesi

Quantitative bounds on Lorentz symmetry violation in the neutrino sector have been obtained by analyzing existing laboratory data on neutron decay and pion leptonic decays. In…

Spectrum of the Y=2 Pentaquarks

F. Buccella, D. Falcone, F. Tramontano

By assuming a mass formula for the spectrum of the Y=2 pentaquarks, where the chromo-magnetic interaction plays a main role, and identifying the lightest state with the Theta^+(154…

The statistical parton distributions: status and prospects

Claude Bourrely, Jacques Soffer, Franco Buccella

New experimental results on polarized structure functions, cross sections for neutral and charge current reactions and () charge current on isoscalar targets…

Semileptonic decays of Bc mesons into charmonium states in a relativistic quark model

Mikhail A. Ivanov, Juergen G. Korner, Pietro Santorelli

We use the framework of a relativistic constituent quark model to study the semileptonic transitions of the Bc meson into CCbar charmonium states where CCbar = etaC (1S0), J/psi (3…
