A Novel Supernova Detector
We discuss the prospects for detecting nu_{mu,tau} and nu_{tau}neutrinos from
Type II supernovas using the novel detector at the Supernova Burst Observatory
(SNBO) or OMNIS that is being designed for an underground laboratory in the
USA. This detector would collect ~2000 flavor selected events from a Galactic
supernova and could probe neutrino mass down to a few eV, as well as the
dynamics of the supernova process. We believe this is essential to further our
understanding of the neutrino section of elementary particle physics.Comment: 4 pages containing 5 figures, 4 tables; workshop on Next Generation

Is the LMA solar-neutrino solution ruled out by SN1987A data?
The development of new supernova neutrino detectors relies on the expected
hard energy spectrum of the nu_mu and nu_tau emitted in the supernova. We show
that SN1987A was sensitive to the large mixing angle (LMA) and "just so"
solution to the solar neutrino problem. We review the previous analysis of the
SN1987A data and propose a new analysis. The results of this analysis strongly
disfavor the LMA solution, provided the nu_mu and nu_tau are hard as predictedComment: 4 pages; 6 figures. Presented at the Europhysics Neutrino Oscillation

MSSM inflaton: SUSY dark matter and LHC
In this talk we will discuss how inflation can be embedded within a minimal
extension of the Standard Model where the inflaton carries the Standard Model
charges. There is no need of an ad-hoc scalar field to be introduced in order
to explain the temperature anisotropy of the cosmic microwave background
radiation, all the ingredients are present within a minimal supersymmetric
Standard Model. For the first time inflaton properties can be directly linked
to the particle phenomenology, dark matter, and the baryons of the Standard
Model.Comment: 6 Pages, UCLA DM 200
