Maximal $D = 5$ trombone supergravity from M5-branes and $SU (2)$ -flavoured $N = 1$ class $S$ operator spectra

Ritabrata Bhattacharya, Abhay Katyal, Oscar Varela

We recently presented a new $D = 5$ $N = 8$ gauged supergravity involving the local trombone scaling symmetry. It arises by consistent truncation of M-theory on the internal…

Large- $N$ Torus Knots in Lens Spaces and Their Quiver Structure

Ritabrata Bhattacharya, Suvankar Dutta, Naman Pasari +1

We study torus knot invariants in the lens space $S^{3} / Z_{p}$ within Chern--Simons theory. Using the surgery and modular description of lens spaces, we derive a general e…

Crossing symmetry including non planar diagrams in perturbative QFT

Ritabrata Bhattacharya

We venture a proof of crossing symmetry for non-planar diagrams in perturbative QFT. For the planar diagrams a proof of crossing is available in the literature and our method close…

Class $S$ superconformal indices from maximal supergravity

Ritabrata Bhattacharya, Abhay Katyal, Oscar Varela

We present a new gauging of maximal supergravity in five spacetime dimensions with gauge group containing ISO(5), involving the local scaling symmetry of the metric, and admitting…
