Parity-violating πNN coupling constant from the flavor-conserving effective weak chiral Lagrangian
Physics Letters B, 2017 We investigate the parity-violating pion–nucleon–nucleon coupling constant hπNN1, based on the chiral quark-soliton model. We employ an effective weak Hamiltonian that takes into account the next-to-leading order corrections from QCD to the weak ...

On the off-shell superfield Lagrangian formulation of 4D, N=1 supersymmetric infinite spin theory
Physics Letters B, 2022 We develop a complete off-shell Lagrangian description of the free 4D,N=1 supersymmetric theory of infinite spin. Bosonic and fermionic fields are formulated in terms of spin-tensor fields with dotted and undotted indices.

2, 12, 117, 1959, 45171, 1170086, …: a Hilbert series for the QCD chiral Lagrangian
Journal of High Energy Physics, 2021 We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation is

Fixed points of (0,2) Landau-Ginzburg renormalization group flows and the chiral algebra
Journal of High Energy Physics, 2022 We discuss renormalization group flows in two-dimensional quantum field theories with (0,2) supersymmetry. We focus on theories with UV described by a Landau-Ginzburg Lagrangian and use the chiral algebra to constrain the IR dynamics. We present examples

Isospin Symmetry Breaking in Non-Perturbative QCD
Physical Sciences Forum, 2023 At finite isospin chemical potential μI, the tension between measured decays and partial branching ratios of neutral and charged bosons as functions of dimuon mass squared and the Standard Model (SM) isospin asymmetry can be analyzed in nonperturbative ...

Low-energy effective description of dark $Sp(4)$ theories
SciPost Physics, 2023 Strongly interacting massive particles are viable dark matter candidates. We consider a dark $Sp(4)$ gauge theory with $N_f=2$ fermions in the pseudo-real fundamental representation and construct the chiral low-energy effective theory.

Nonlinear (chiral) p-form electrodynamics
Journal of High Energy Physics, 2022 In our previous article Phys. Rev. Lett. 127 (2021) 271601, we announced a novel ‘democratic’ Lagrangian formulation of general nonlinear electrodynamics in four dimensions that features electric and magnetic potentials on equal footing. Here, we give an

Unitarized one-loop graviton-graviton scattering [PDF]
EPJ Web of Conferences, 2022 In this work we interpret the Einstein-Hilbert (EH) Lagrangian of gravitation as the first term of a low-energy effective theory similar to those considered in the chiral Lagrangian approach to low-energy hadron physics or the electroweak chiral ...

N = 3 chiral supergravity compatible with the reality condition and higher N chiral Lagrangian density [PDF]
, 2001 We obtain N = 3 chiral supergravity (SUGRA) compatible with the reality condition by applying the prescription of constructing the chiral Lagrangian density from the usual SUGRA.

Chiral physics in the magnetic field with quark confinement contribution
European Physical Journal C: Particles and Fields, 2018 The standard chiral perturbation theory is known to predict much weaker effects in magnetic field, than found in numerical lattice data. To overcome this disagreement we are using the effective chiral confinement Lagrangian, $$L_{ECCL}$$ LECCL ...
