Unitary Dual-Resonance S-matrices
Claudia de Rham, Andrew J. Tolley, Zhuo-Hui Wang +1
Dual-resonance models realize crossing symmetry, Regge behavior and infinitely many resonances in a compact analytic form but their canonical tree-level realizations fall short of…
Diffeomorphic Scalar Duality
Claudia de Rham, Andrew J. Tolley
We show that every local scalar effective field theory admits a new kind of duality to an infinite class of local scalar field theories with distinct Lagrangians. The duality map t…
Schwinger-Keldysh Path Integral for Gauge theories
Greg Kaplanek, Maria Mylova, Andrew J. Tolley
We develop the Schwinger-Keldysh path-integral formalism for open non-Abelian gauge theories that are gauge-fixed via the BRST method in covariant gauges. We focus on generic initi…
Gauging Open EFTs from the top down
Greg Kaplanek, Maria Mylova, Andrew J. Tolley
We present explicit top-down calculations of Open EFTs for gauged degrees of freedom with a focus on the effects of gauge fixing. Starting from the in-in contour with two copies of…
Primal S-matrix bootstrap with dispersion relations
Claudia de Rham, Andrew J. Tolley, Zhuo-Hui Wang +1
We propose a new method for constructing the consistent space of scattering amplitudes by parameterizing the imaginary parts of partial waves and utilizing dispersion relations, cr…
Graviton propagation in ghost-free massive gravity
Claudia de Rham, Jan Kożuszek, Andrew J. Tolley +1
We consider the ghost-free dRGT massive gravity with two of its three possible mass terms. This theory has five gravitational degrees of freedom. On Minkowski spacetime these modes…
