Non-invertible Chiral Symmetry and Axions under Electromagnetic Duality
Gongjun Choi, Tony Gherghetta, John Terning
We study the implications of non-invertible chiral symmetry in a four-dimensional U(1) gauge theory coupled to massless fermions with electromagnetic duality. Th…
Supergravity from the Bottom Up
Tony Gherghetta, Wenqi Ke
We employ on-shell methods to construct scattering amplitudes and derive effective theories involving massive spin-3/2 fermions interacting with spin 0, 1 and 2 bosons. The four-po…
Testing the Scalar Weak Gravity Conjecture in No-scale Supergravity
Emilian Dudas, Tony Gherghetta, Keith A. Olive +1
We explore possible extensions of the Weak Gravity Conjecture (WGC) to scalar field theories. To avoid charged black hole remnants, the WGC requires the existence of a particle wit…
Supergravity Scattering Amplitudes
Emilian Dudas, Tony Gherghetta, Keith A. Olive +1
Supergravity theories with non-minimal Kähler potentials are characterized by a non-trivial field space manifold with corresponding non-trivial kinetic terms. The scattering amplit…
Out of this world neutrino oscillations
Tony Gherghetta, Andrey Shkerin
We study how vacuum neutrino oscillations can be affected by a causal, nonlinear and state-dependent modification of quantum field theory that may be interpreted using the many-wor…
Small Instantons in Weakly-Gauged Holographic Models
Tony Gherghetta, Alex Pomarol
Small instantons can play an important role in Yang-Mills theories whose gauge couplings are sizeable at small distances. An interesting class of theories where this could occur is…
