Asymmetric lepton production in a universe with non-zero baryon number

Sivaram, C (Springer, 1982-03)

Due to processes occurring during different stages of stellar evolution, a universe with a net baryon number develops an excess of neutrinos and positrons over antineutrinos of the same order as the observed relative ...
Cosmic ray constraints on neutron-antineutron and hydrogen-antihydrogen oscillation time scales

Sivaram, C (INSDOC, 1983-08)

Recently some modifications of the usual GUTS models have been proposed where global baryon-lepton symmetry is spontaneously broken, leading to neutron-antineutron and hydrogen-antihydrogen oscillations. The possible ...
Do leptons generate gravity? First laboratory constraints obtained from some /G experiments and possibility of a new decisive constraint

Unnikrishnan, C. S; Gillies, G. T (Elsevier, 2001-09)

The equivalence of the active and passive gravitational masses has been tested in the laboratory to an accuracy of about 5 parts in 105. However, this level of sensitivity is not enough to answer the important question ...
Lepton loss and entropy generation in stellar collapse

Datta, B; Deo, P. P (D. Reidel Publishing Co., 1983-02)

The effects of uncertainties in determining the loss of neutrinos and the generation of entropy during the collapse of a stellar core are studied using a simple spherically-symmetric homologous collapse model with an ...
