: Simplify Massive Spinor Helicity
Aakash Kumar, Arnab Rudra, Rahul Shaw
We present , a package to do spinor helicity computations in four spacetime dimensions $\href{https://github.com/aakash-kmr/SMaSH}{\text{(git…
Compton amplitude and Contact term(s) in the Spinor Helicity formalism
Aakash Kumar, Arnab Rudra, Rahul Shaw
In gauge theories, contact terms play an important role in ensuring gauge invariance. In the spinor helicity formalism, the choice of a gauge-fixing condition manifests itself in t…
Compton amplitude for massive bosons of arbitrary spin
Aakash Kumar, Arnab Rudra, Manav Shah +1
In this work, we write down an analytic expression of electromagnetic tree-level Compton amplitude for a completely symmetric traceless (bosonic) higher spin particle in any dimens…
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…
