The electroweak chiral Lagrangian reanalyzed [PDF]

open access: yesPhysical Review D, 2000
44 pages, Revtex. v2: Sections II and III interchanged. New section II now self-contained. Discussions improved in sections I, II, V.C and VI. Conclusions unchanged.

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.

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

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 ...

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

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.

A toolkit for twisted chiral superfields

open access: yesJournal of High Energy Physics, 2020
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.

CP asymmetry in the angular distribution of τ → KS πν τ decays

open access: yesJournal of High Energy Physics, 2020
In this work, we study the C P asymmetry in the angular distribution of τ → K S πν τ decays, taking into account the known C P violation in K 0 − K ¯ 0 $$ {K}^0-{\overline{K}}^0 $$ mixing. It is pointed out for the first time that, once the well-measured

Supergravity with mimetic dark matter

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We formulate a supersymmetric version of gravity with mimetic dark matter. The coupling of a constrained chiral multiplet to $$N = 1$$ N = 1 supergravity is made locally supersymmetric using the rules of tensor calculus.
