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…
