Quivers for coloured planar theories at all loop orders for scattering processes from Feynman diagrams
Prafulla Oak
We introduce Feynman-like rules to compute quivers for two loops and higher for the coloured planar theory for winding number zero. We demonstrate this for a few cases. Then…
Towards a categorification of scattering amplitudes
Severin Barmeier, Prafulla Oak, Aritra Pal +2
Categorification of scattering amplitudes for planar Feynman diagrams in scalar field theories with a polynomial potential is reported. Amplitudes for cubic theories are directly w…
Computing quivers for two and higher loops for the colored planar theory
Prafulla Oak
We introduce Feynman-like rules to compute quivers for two loops and higher for the coloured planar theory for winding number zero. We demonstrate this for a few cases.
Holographic Beta functions for the Generalized Sine Gordon Theory
Prafulla Oak, B. Sathiapalan
The Sine Gordon theory is generalized to include several cosine terms. This is similar to the world sheet description of a string propagating in a tachyon background. This model is…
Exact Renormalization Group and Sine Gordon Theory
Prafulla Oak, B. Sathiapalan
The exact renormalization group is used to study the RG flow of quantities in field theories. The basic idea is to write an evolution operator for the flow and evaluate it in pertu…
