Chiral physics in the magnetic field with quark confinement contribution
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 ...

A toolkit for twisted chiral superfields
We calculate the most general terms for arbitrary Lagrangians of twisted chiral superfields in 2D (2,2) supersymmetric theories [1]. The scalar and fermion kinetic terms and interactions are given explicitly.

Unitarized one-loop graviton-graviton scattering [PDF]
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]
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.

A systematic approach to the SILH Lagrangian
We consider the electroweak chiral Lagrangian, including a light scalar boson, in the limit of small ξ=v2/f2. Here v is the electroweak scale and f is the corresponding scale of the new strong dynamics.

Self-interacting chiral p-forms in higher dimensions
There exists no natural variational principle for the dynamics of abelian p-form potentials with self-dual field strengths, also called chiral p-forms. Relying on the PST method, we establish the general consistency condition for a Lagrangian to describe

Parity-violating πNN coupling constant from the flavor-conserving effective weak chiral Lagrangian
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 ...

Isospin-breaking effects in the three-pion contribution to hadronic vacuum polarization
Isospin-breaking (IB) effects are required for an evaluation of hadronic vacuum polarization at subpercent precision. While the dominant contributions arise from the e + e − → π + π − channel, also IB in the subleading channels can become relevant for a ...

Baryon Chiral Perturbation Theory in the 1/N Expansion [PDF]
The chiral Lagrangian for baryons is formulated in an expansion in 1/N_c. The chiral Lagrangian implements the contracted spin-flavor symmetry of large-N_c baryons as well as nonet symmetry of the leading planar diagrams. Large-N_c consistency conditions
