Quantizable Ghost-ridden theories using Kinetic Positivity Constraints
Sukanta Panda, Archit Vidyarthi
We present a novel way to constrain the ghost field with respect to other physical fields present in a given theory such that the theory becomes quantizable. This is achieved by im…
Local momentum space: Scalar field and gravity
Sukanta Panda, Abbas Altafhussain Tinwala, Archit Vidyarthi
We use the local momentum space technique to obtain an expansion of the Feynman propagators for scalar field and graviton up to first order in the background curvature. The express…
Covariant Effective Action for Generalized Proca Theories
Sukanta Panda, Abbas Tinwala, Archit Vidyarthi
We investigate quantum stability of the generalised Proca theories in curved spacetime treating gravity as a dynamical field. To compute the quantum gravitational corrections we ev…
Covariant Effective Action for Scalar-Tensor Theories of Gravity
Sandeep Aashish, Sukanta Panda, Abbas Altafhussain Tinwala +1
We develop the calculation of the divergent part of one-loop covariant effective action for scalar fields minimally and non-minimally coupled to gravity using the generalized Schwi…
