We have studied the predictions for the LSP decay within the framework of a radiatively broken unified supergravity model without R-parity. Assuming that Higgs/slepton mixing is the only source of R-parity breaking and responsible for the observed neutrino oscillations we obtain predictons for the LSP life-time and branching fractions.

In this paper we study the chiral symmetry breaking in the hard wall AdS/QCD model. We solve the equations of motion up to the second order at large momentum and obtain the first few terms in the expansion of the ”left-right” correlator, which is the measure of symmetry breaking. In the strong coupling calculation we get the result as the series in square root of t’Hooft constant.

We discuss the structure of topological defects in the context of extra dimensions where the symmetry breaking terms are localized. These defects develop structure in the extra dimension which differs from the case where symmetry breaking is not localized. This new structure can lead to corrections to the mass scale of the defects which is not captured by the effective theory obtained by integr...

Abstract. Manifestation of Ricci scalar like a matter field as well as a geometrical field, at high energy, has been noted earlier [9], Here, its interaction, with another scalar field is considered in four-dimensional curved space-time. This interaction leads to the production of a large number of pairs of spinless particle-antiparticle due to expansion of the early universe in the vacuum stat...

The Einstein equations for a perfect fluid spatially homogeneous spacetime are studied in a unified manner by retaining the generality of certain parameters whose discrete values correspond to the various Bianchi types of spatial homogeneity. A parameter dependent decomposition of the metric variables adapted to the symmetry breaking effects of the nonabelian Bianchi types on the “free dynamics...

I discuss some new trends in Particle Theory beyond the Standard Model. Some topics which are briefly covered include electroweak baryogenesis, gauge versus non-gauge discrete symmetries, the strong-CP problem, dynamical symmetry breaking scenarios, supersymmetric grand unification, new aspects in low-energy supersymmetry and superstring phe-

When 4-dimensional general relativity is extended by a 3-dimensional grav-itational Chern-Simons term an apparent violation of diffeormorphism invari-ance is extinguished by the dynamical equations of motion for the modified theory. The physical predictions of this recently proposed model show little evidence of symmetry breaking, but require the vanishing of the Pontryagin density.

the effect of prepared ayurvedic formulation was evaluated on excision and incision wound models in rats. the wound-healing activity was assessed by the rate of period of epithelialization and skin-breaking strength. histological study of the granulation tissue was carried out to know the extent of collagen formation in the wound tissue. the ayurvedic formulation prepared was then promoted for ...
