Radion signature in scattering
S. R. Choudhury, A. S. Cornell, G. C. Joshi
We investigate the phenomenological consequences of the possible existence of the radion at a TeV-scale for scattering in the TeV range. We find that polarized cross-sections…
Gravitational Lensing and Extra Dimensions
Xiao-Gang He, Girish C. Joshi, Bruce H. J. McKellar
We study gravitational lensing and the bending of light in low energy scale (M_S) gravity theories with extra space-time dimensions n. We find that due to the presence of spin-2 Ka…
Constrained systems described by Nambu mechanics
C. C. Lassig, G. C. Joshi
Using the framework of Nambu's generalised mechanics, we obtain a new description of constrained Hamiltonian dynamics, involving the introduction of another degree of freedom in ph…
An Octonionic Gauge Theory
C. C. Lassig, G. C. Joshi
The nonassociativity of the octonion algebra necessitates a bimodule representation, in which each element is represented by a left and a right multiplier. This representation can…
