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…
