Generation of Neutrino mass in a Kalb-Ramond Background in large extra dimensions
Soumitra SenGupta, Aninda Sinha
In this paper we investigate whether spacetime torsion induced by a Kalb-Ramond field in a string inspired background can generate a mass for the left-handed neutrino. We consider…
The Meaning of Maximal Symmetry in Presence of Torsion
Debashis Gangopadhyay, Soumitra Sengupta
We show that the usual physical meaning of maximal symmetry can be made to remain unaltered even if torsion is present. All that is required is that the torsion fields satisfy some…
Construction of Maximally Symmetric Solutions for the Metric
Debashis Gangopadhyay, Soumitra Sengupta
We construct new maximally symmetric solutions for the metric. We then show that for a string moving in a background consisting of maximally symmetric gravity, dilaton field and se…
Generalising The Concept Of Maximal Symmetry Of Spacetimes In The Presence Of Torsion
Debashis Gangopadhyay, Soumitra Sengupta
A possible generalisation is given to the meaning of maximal symmetry in the presence of torsion
