Minimal isometric dilations and operator models for the polydisc
Sourav Pal, Prajakta Sahasrabuddhe
For commuting contractions acting on a Hilbert space with , we find a necessary and sufficient condition under which $(T_1,\dots…

Multiparton Cwebs at five loops
Shubham Mishra, Sourav Pal, Aditya Srivastav +1
Scattering amplitudes involving multiple partons are plagued with infrared singularities. The soft singularities of the amplitude are captured by the soft function which is defined…

Correlator webs of massive multiparton amplitudes at four loops: A study of boomerang webs
Neelima Agarwal, Sourav Pal, Aditya Srivastav +1
Logarithm of the soft function can be organized into sets of Feynman diagrams known as Cwebs. We introduced a new formalism in~\cite{Agarwal:2022wyk}, that allows to determine seve…
