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…
Duality defects in -type Niemeier lattice CFTs
Sachin Grover, Subramanya Hegde, Dileep P. Jatkar
We discuss the construction of duality defects in meromorphic CFTs that correspond to Niemeier lattices. We will illustrate our constructions for the -type lattices. We…
Looking for the Higgs Branch of 4D Rank 1 SCFTs
Md. Abhishek, Sachin Grover, Dileep P. Jatkar +1
The Schur index of the Higgs branch of 4-dimensional SCFTs is related to the spectrum of non-unitary 2-dimensional CFTs. The rank 1 case has been shown to lead to t…
