Diluted mass gap in strongly coupled non-local Yang-Mills

Journal of High Energy Physics, 2021
We investigate the non-perturbative regimes in the class of non-Abelian theories that have been proposed as an ultraviolet completion of 4-D Quantum Field Theory (QFT) generalizing the kinetic energy operators to an infinite series of higher-order ...

General Fractional Noether Theorem and Non-Holonomic Action Principle

Mathematics, 2023
Using general fractional calculus (GFC) of the Luchko form and non-holonomic variational equations of Sedov type, generalizations of the standard action principle and first Noether theorem are proposed and proved for non-local (general fractional) non ...

To Half-Be or Not To Be?

Journal of High Energy Physics, 2023
It has recently been argued that half degrees of freedom could emerge in Lorentz and parity invariant field theories, using a non-linear Proca field theory dubbed Proca-Nuevo as a specific example.

A class of static spherically symmetric solutions in f(Q)-gravity

European Physical Journal C: Particles and Fields, 2023
We analyze a class of topological static spherically symmetric vacuum solutions in f(Q)-gravity. We considered an Ansatz ensuring that those solutions trivially satisfy the field equations of the theory when the non-metricity scalar is constant.

A pitfall in applying non-anticommuting $γ_5$ in $q\overline{q} \rightarrow ZH$ amplitudes

SciPost Physics Proceedings, 2022
In computing the two-loop QCD corrections to a class of Feynman diagrams for the process $q\overline{q} \rightarrow ZH$ in Higgs effective field theory, we discover a striking phenomenon.

Injecting the UV into the bootstrap: Ising Field Theory

Journal of High Energy Physics, 2023
We merge together recent developments in the S-matrix bootstrap program to develop a dual setup in 2 space-time dimensions incorporating scattering amplitudes of massive particles and matrix elements of local operators.

The constraints of post-quantum classical gravity

Journal of High Energy Physics, 2022
We study a class of theories in which space-time is treated classically, while interacting with quantum fields. These circumvent various no-go theorems and the pathologies of semi-classical gravity, by being linear in the density matrix and phase-space ...

Integrable Floquet systems related to logarithmic conformal field theory

SciPost Physics, 2023
We study an integrable Floquet quantum system related to lattice statistical systems in the universality class of dense polymers. These systems are described by a particular non-unitary representation of the Temperley-Lieb algebra.

Relative defects in relative theories: Trapped higher-form symmetries and irregular punctures in class S

SciPost Physics, 2022
A relative theory is a boundary condition of a higher-dimensional topological quantum field theory (TQFT), and carries a non-trivial defect group formed by mutually non-local defects living in the relative theory.

Hamiltonian analysis of an on-shell U(1) gauge field theory

Physics Letters B, 2017
We perform the Hamiltonian analysis of an on-shell U(1) gauge field theory, in which the action is not invariant under local U(1) transformations but recovers the invariance when the equations of motion are imposed.
