Three point interaction of Dirac fermions with higher spin particles and discrete symmetries
Kushal Chakraborty, Aakash Kumar, Arnab Rudra +1
We constructed all possible kinematically allowed three-point interactions of two massless Dirac spinors with massive higher-spin bosons. In any spacetime, the interactions hav…
On-shell Supersymmetry and higher-spin amplitudes
Mahesh K. N. Balasubramanian, Kushal Chakraborty, Arnab Rudra +1
We use on-shell Supersymmetry to constrain the three-point function of two massless particles and one massive particle in 3+1 dimensions. We use this information to write down the…
Large Invariants of Torus Links in Lens Spaces
Kushal Chakraborty, Suvankar Dutta
We compute the invariants for a class of knots and links in arbitrary representations in in the large (level), large (rank) limit, keeping fi…
New phase in Chern-Simons theory on lens space
Kushal Chakraborty, Suvankar Dutta
We consider Chern-Simons theory on in Seifert framing and write down the partition function as a unitary matrix model. In the large and large limit the eigen…
Detector response along null geodesics in black hole spacetimes and in a Friedmann-Lemaitre-Robertson-Walker Universe
Kushal Chakraborty, Bibhas Ranjan Majhi
We study the detector's response when moving along an ingoing null geodesic. The backgrounds are chosen to be black hole spacetimes ( dimensional Schwarzschild metric and ne…
