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…
