A detailed model is constructed for the calculation of electron capture rates of some fp-shell nuclei for situations prevailing in pre-supernova and collapse phases of the evolution of the core of massive stars leading to supernova explosion. The mod

Half-lives and pre-supernova weak interaction rates for nuclei away from the stability line

Autor: Kar, K., Chakravarti, S., Ray, A., Sarkar, S.

Publikováno v: J.Phys.G24:1641-1645,1998

A detailed model for the calculation of beta decay rates of the $fp$ shell nuclei for situations prevailing in pre-supernova and collapse phases of evolution of the core of massive stars leading to supernova explosion has been extended for electron-c

Signatures of Virtual LSPs at the Tevatron

Autor: Datta, A., Chakravarti, S., Guchait, M.

Publikováno v: Z.Phys.C68:325-330,1995

Relatively light sneutrinos which are experimentally allowed and are not theoretically disfavoured may significantly affect the currently popular search strategies for supersymmetric particles by decaying dominantly into an invisible channel. In cert

S-wave $\pi$-Nucleus Repulsion and Dirac Phenomenology

Autor: Chakravarti, S., Jennings, B. K.

Publikováno v: Phys.Lett. B323 (1994) 253-256

A relativistic $\pi$-nucleon potential is extended to $m^* \neq m$ to investigate the possibility of generating s-wave $\pi$-nucleus repulsion. We find that relativity does indeed generate significant repulsion, the exact amount depending on the deta
