Double Copy from the Flipped Null String

Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +2

We study the double-copy structure of tree amplitudes of the bosonic null string in the flipped vacuum. We show that its level-one vector correlator supplies the Cachazo-He-Yuan (C…

Scattering of Null strings - Flipped Vacuum & CHY

Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +2

We investigate the scattering of null tensionless strings. Classical null strings, given by the ILST action, give rise to three distinct quantum theories built on different vacua a…

Doubly-scaled planar SYM & Carroll Holography

Arjun Bagchi, Prateksh Dhivakar, Alok Laddha +1

In their seminal paper, Okuda and Penedones (OP) put forward an intriguing proposal towards holography in asymptotically flat spacetimes (AFS). They showed that the flat space limi…

Carrollian ABJM: Fermions and Supersymmetry

Arjun Bagchi, Arthur Lipstein, Saikat Mondal +1

A natural approach for constructing a concrete example of flat space holography is to take the flat space limit of a well-understood example of AdS/CFT, such as the one relating M-…

High energy scattering and null strings

Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer +1

We propose an instrinsic worldsheet description of the ultra-high energy regime of string scattering based on worldsheet symmetries. At very high energies, the fundamental string b…

Black hole Near Horizons through the Looking Glass

Arjun Bagchi, Arkachur Bhattacharya, Sharang Rajesh Iyer +1

We show that the near horizon of a generic non-extremal black hole (BH) can be understood in terms of a Carrollian geometry with two null directions, also called a String-Carroll (…
