The simplest unified extension of the Minimal Supersymmetric Standard Model with bi-linear R–Parity violation naturally predicts a hierarchical neutrino mass spectrum, in which one neutrino acquires… (More)

We have reconsidered the atmospheric neutrino anomaly in light of the latest data from Super–Kamiokande contained events and from Super–Kamiokande and MACRO up-going muons. We have reanalysed the… (More)

Prompted by recent solar and atmospheric data, we re-analyze the four-neutrino description of current global neutrino oscillation data, including the LSND evidence for oscillations. The higher degree… (More)

We consider the impact of nonstandard interactions (NSI) of neutrinos on the determination of neutrino mixing parameters at a neutrino factory using nu(-)(e)-->nu(-)(mu) "golden channels" for the… (More)

We give an analytical calculation of solar neutrino masses and mixing at one-loop order within bilinear R-parity breaking supersymmetry, and compare our results to the exact numerical calculation.… (More)

We analyse the impact of recent solar and atmospheric data in the determination of the neutrino oscillation parameters, taking into account that both the solar νe and the atmospheric νμ may convert… (More)

A global analysis of spin-flavour precession (SFP) solutions to the solar neutrino problem is given, taking into account the impact of the full set of latest solar neutrino data, including the recent… (More)

The simplest unified extension of the Minimal Supersymmetric Standard Model with bi-linear R– Parity violation provides a predictive scheme for neutrino masses which can account for the observed… (More)

Using the most recent atmospheric neutrino data, as well as short-baseline, longbaseline and tritium β-decay data we show that the joint interpretation of the LSND, solar and atmospheric neutrino… (More)

Successful leptogenesis within the simplest type I supersymmetric seesaw mechanism requires the lightest of the three right-handed neutrino supermultiplets to be heavier than approximately 10(9) GeV.… (More)
