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…
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…
and Carrollian Holography
Amartya Saha
In a D Carrollian conformal field theory, the Ward identities of the two local fields and , entirely built out of the Carrollian conformal stress-tensor, contai…
Carrollian Approach to D Flat Holography
Amartya Saha
The isomorphism between the (extended) BMS algebra and the D Carrollian conformal algebra hints towards a co-dimension one formalism of flat holography with the field theo…
Non-Lorentzian Kač-Moody Algebras
Arjun Bagchi, Ritankar Chatterjee, Rishabh Kaushik +2
We investigate two dimensional (2d) quantum field theories which exhibit Non- Lorentzian Kač-Moody (NLKM) algebras as their underlying symmetry. Our investigations encompass both 2…
Intrinsic Approach to D Carrollian Conformal Field Theory
Amartya Saha
The 3D Bondi-Metzner-Sachs (BMS) algebra that is the asymptotic symmetry algebra at null infinity of the D asymptotically flat space-time is isomorphic to the D Carro…
BMS Modular Diaries: Torus one-point function
Arjun Bagchi, Poulami Nandi, Amartya Saha +1
Two dimensional field theories invariant under the Bondi-Metzner-Sachs (BMS) group are conjectured to be dual to asymptotically flat spacetimes in three dimensions. In this paper,…
BMS Characters and Modular Invariance
Arjun Bagchi, Amartya Saha, Zodinmawia
We construct the characters for the highest weight representations of the 3d Bondi-Metzner-Sachs (BMS) algebra. We then use these to construct the partition function and show h…
