The Shapiro Phase Shift on Pulsars (SPSP) influence at low , but detectable level the pulsars’ (PSR) periods and their derivatives. This effect may be already written in PSRs’ time derivative deviation and in particular it may explain the presence of a few negative pulse derivatives among 558 known PSRs. We describe in detail the phenomenon and predict that the SPSP may play a role in Ṗ deviati...

The solar neutrino problem, atmospheric neutrino problem and the hot dark matter which seems to be required by galaxy formation can all be most economically described by three very degenerate neutrinos with a common mass of a few eV. Such neutrino masses could also be relevant for the recent data on double beta decay. We provide an existence proof for such a scenario by constructing an explicit...

This work investigates the dark matters structures that form on the smallest cosmological scales. We find that the types and abundances of structures which form at approximately Earth-mass scales are very sensitive to the nature of dark matter. We explore various candidates for dark matter and determine the corresponding properties of small-scale structure. In particular, we discuss possibiliti...

First Results from the Cryogenic Dark Matter Search Experiment at the Deep Site

We consider the constrained minimal supersymmetric standard model which emerges from one theory with a small deviation from Yukawa unification which is adequate for μ > 0. We show that this model possesses a wide and natural range of parameters which is consistent with the data on b → sγ, the muon anomalous magnetic moment, the cold dark matter abundance in the universe, and the Higgs boson mas...

We enlarge our set of supersymmetric models and update accelerator constraints in our precise calculation of the relic density of the lightest neutralino, which includes relativistic Boltzmann averaging, subthreshold and resonant annihilations, and coannihilation processes among charginos and neutralinos.
