Ghost-free Electroweak Symmetry Breaking with Weakly Nonlocal Interactions
Pratik Chattopadhyay, Florian Nortier
Weakly nonlocal (WNL) Quantum Field Theories (QFT's) may define a new class of UV-completions in particle physics and gravity, without introducing any new elementary particle. One…
Anomalies in String-inspired Non-local Extensions of QED
Fayez Abu-Ajamieh, Pratik Chattopadhyay, Anish Ghoshal +1
We investigate anomalies in the class of non-local field theories that have been proposed as an ultraviolet completion of 4-D Quantum Field Theory (QFT) with generalizing the kinet…
Aspects of self-dual Yang-Mills and self-dual gravity
Pratik Chattopadhyay
In this thesis, we study the all same helicity loop amplitudes in self-dual Yang-Mills and self-dual gravity. These amplitudes have long been conjectured to be interpreted as an an…
One-loop same helicity YM amplitudes from BG currents
Pratik Chattopadhyay, Kirill Krasnov
We propose and prove a new formula for the one-loop all same helicity Yang-Mills amplitudes. These amplitudes are seen to arise as a sum of products of two tree-level Berends-Giele…
One-loop same helicity four-point amplitude from shifts
Pratik Chattopadhyay, Kirill Krasnov
It has been suggested a long time ago by W. Bardeen that non-vanishing of the one-loop same helicity YM amplitudes, in particular such an amplitude at four points, should be interp…
Discrete symmetries for electroweak natural type-I seesaw mechanism
Pratik Chattopadhyay, Ketan M. Patel
The naturalness of electroweak scale in the models of type-I seesaw mechanism with Yukawa couplings requires TeV scale masses for the fermion singlets. In this case,…
