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.

Class Field Theory and Elliptic Curves with Complex Multiplication [PDF]

, 2023
openClass field theory is a branch of algebraic number theory which has the purpose of studying and classifying abelian extensions of fields. The work starts with a detailed study of this theory based on a cohomological approach which leads to the ...

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.

Lorentzian dynamics and factorization beyond rationality

Journal of High Energy Physics, 2021
We investigate the emergence of topological defect lines in the conformal Regge limit of two-dimensional conformal field theory. We explain how a local operator can be factorized into a holomorphic and an anti-holomorphic defect operator connected ...

Higher-rank tensor non-Abelian field theory: Higher-moment or subdimensional polynomial global symmetry, algebraic variety, Noether's theorem, and gauging

Physical Review Research, 2021
With a view toward a fracton theory in condensed matter, we introduce a higher-moment polynomial degree-p global symmetry, acting on complex scalar/vector/tensor fields (e.g., ordinary or vector global symmetry for p=0 and p=1 respectively).

Coupling between downstream variations of channel width and local pool–riffle bed topography [PDF]

Earth Surface Dynamics, 2023
A potential control of downstream channel width variations on the structure and planform of pool–riffle sequence local bed topography is a key to the dynamics of gravel bed rivers.
