Soft Algebras via Bulk Double Soft Limits
Sruthi A. Narayanan
Soft and collinear limits of "celestial amplitudes" give rise to infinite dimensional symmetry algebras for two-dimensional (2D) "celestial" conformal field theories (CFTs). A smal…
Memory Correlators and Ward Identities in the 'in-in' Formalism
Ian Moult, Sruthi A. Narayanan, Sabrina Pasterski
The symmetries of asymptotically flat spacetimes impose constraints on observables at infinity. The consequences of this have been extensively explored for S-matrix elements, where…
Marginal Operators from Celestial Diamonds
Michael Imseis, Sruthi A. Narayanan, A. W. Peet
For a given conformal field theory (CFT), one can deform it via the addition of a marginal operator to the spectrum. In two dimensions, when the added operator has conformal weight…
Collinear Corrections to the Cachazo-Strominger Soft Theorem
Eivind Jørstad, Sruthi A. Narayanan
Soft theorems describe the behavior of scattering amplitudes when one or several external particles are taken to be energetically soft. In tree-level gravity there are universal so…
Marginality from Leading Soft Gluons
Sruthi A. Narayanan
Marginal operators in a d-dimensional conformal field theory (CFT), those with conformal dimension , give us information about the space of related theories. This can be incre…
Approaching the conformal WZW behavior in the infrared limit of two-dimensional massless QCD: a lattice study
Nikhil Karthik, Rajamani Narayanan, Sruthi A. Narayanan
Two-dimensional QCD with colors and flavors of massless fermions in the fundamental representation is expected to exhibit conformal behavior in the infrared governed by…
Celestial Gluon Amplitudes from the Outside In
Walker Melton, Sruthi A. Narayanan
We show that, given a two-dimensional realization of the celestial OPE in self-dual Yang-Mills, we can find a scalar source around which scattering amplitudes replicate correlation…
Spectrum of two-dimensional gauge theories coupled to massless fermions in integer representations
Rajamani Narayanan, Sruthi A. Narayanan
The spectra of two-dimensional gauge theories coupled to a single massless Majorana fermion in integer representations, , are numerically investigated using the Discrete…
