Monopoles, Clarified

open access: yesFortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Refining the scalar and tensor contributions in τ → πππν τ decays

open access: yesJournal of High Energy Physics, 2017
In this article we analyze the contribution from intermediate spin-0 and spin-2 resonances to the τ → νπππ decay by means of a chiral invariant Lagrangian incorporating these mesons.

Generalized positivity bounds on chiral perturbation theory

open access: yesJournal of High Energy Physics, 2020
Recently, a new set of positivity bounds with t derivatives have been discovered. We explore the generic features of these generalized positivity bounds with loop amplitudes and apply these bounds to constrain the parameters in chiral perturbation theory

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Hidden-charm and hidden-bottom molecular pentaquarks in chiral effective field theory

open access: yesJournal of High Energy Physics, 2019
The newly observed P c (4312), P c (4440) and P c (4457) at the LHCb experiment are very close to the Σ c D ¯ $$ {\varSigma}_c\overline{D} $$ and Σ c D ¯ ∗ $$ {\varSigma}_c{\overline{D}}^{\ast } $$ thresholds.

On 1D, N $$ \mathcal{N} $$ = 4 supersymmetric SYK-type models. Part I

open access: yesJournal of High Energy Physics, 2021
Proposals are made to describe 1D, N $$ \mathcal{N} $$ = 4 supersymmetrical systems that ex- tend SYK models by compactifying from 4D, N $$ \mathcal{N} $$ = 1 supersymmetric Lagrangians involving chiral, vector, and tensor supermultiplets.

Field redefinitions and Plebanski formalism for GR

open access: yes, 2017
We point out that there exists a family of transformations acting on BF-type Lagrangians of gravity, with Lagrangians related by such a transformation corresponding to classically equivalent theories.

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

open access: yesLaser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

On dimensional reduction of 4d N=1 Lagrangians for Argyres-Douglas theories

open access: yes, 2019
Recently, it was found that certain 4d $\mathcal{N}=1$ Lagrangians experience supersymmetry enhancement at their IR fixed point, thereby giving a Lagrangian description for a plethora of Argyres-Douglas theories. A generic feature of these Lagrangians is

Chiral Lagrangian with confinement from the QCD Lagrangian [PDF]

open access: yesPhysical Review D, 2002
An effective Lagrangian for the light quark in the field of a static source is derived systematically using the exact field correlator expansion. The lowest Gaussian term is bosonized using nonlocal colorless bosonic fields and a general structure of effective chiral Lagrangian is obtained containing all set of fields.
