Species Doubling and Chiral Lagrangians [PDF]

open access: yesPhysical Review Letters, 1996
Coupling gauge fields to the chiral currents from an effective Lagrangian for pseudoscalar mesons naturally gives rise to a species doubling phenomenon similar to that seen with fermionic fields in lattice gauge theory.

Relations for low-energy constants in baryon chiral perturbation theory with explicit $$\Delta (1232)$$ Δ ( 1232 ) derived from the chiral quark model

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We study the relations between low-energy constants in the chiral Lagrangians with $$\Delta (1232)$$ Δ ( 1232 ) and those in the quark-level description model up to the third chiral order.

T-dual superstring Lagrangian with double zweibeins

open access: yesJournal of High Energy Physics, 2020
We present superstring Lagrangians with manifest T-duality. The Lagrangian version of the section conditions are necessary to make Lagrangians to be general coordinate invariant. We show the general solution of section conditions.

Chiral Lagrangians and the QCD string [PDF]

open access: yesPhysics Letters B, 1999
We propose a method to derive the low-energy efective action of QCD assuming that the long-distance properties of strong interactions can be described by a string theory. We bypass the usual problems related to the existence of the tachyon and absence of the adequate Adler zero by using a sigma model approach where excitations above the correct ...

Polynomial duality-symmetric lagrangians for free p-forms

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We explore the properties of polynomial Lagrangians for chiral p-forms previously proposed by the last named author, and in particular, provide a self-contained treatment of the symmetries and equations of motion that shows a great economy and simplicity

Chiral Lagrangian for excited pions [PDF]

open access: yesPhysical Review D, 1997
We construct a chiral Lagrangian containing besides the usual pion field (pi) also its first radial excitation (pi'). The Lagrangian is derived by bosonization of a Nambu--Jona-Lasinio quark model with separable non-local interactions, with form factors corresponding to 3-dimensional ground and excited state wave functions.

Determining the leading-order contact term in neutrinoless double β decay

open access: yesJournal of High Energy Physics, 2021
We present a method to determine the leading-order (LO) contact term contributing to the nn → ppe − e − amplitude through the exchange of light Majorana neutrinos. Our approach is based on the representation of the amplitude as the momentum integral of a

A supersymmetric effective chiral Lagrangian [PDF]

open access: yesPhysics Letters B, 1994
We construct in a manifestly supersymmetric form the leading and subleading terms in momentum for an effective supersymmetric chiral Lagrangian in terms of complex pions and their superpartners. A soft supersymmetry breaking term is included and below the supersymmetry breaking scale the Lagrangian reduces to the usual bosonic chiral Lagrangian in ...
