Polynomial duality-symmetric lagrangians for free p-forms
European 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

Introduction to chiral symmetry in QCD [PDF]
EPJ Web of Conferences, 2017 The main aspects of chiral symmetry in QCD are presented. The necessity of its spontaneous breakdown is explained. Some low-energy theorems are reviewed.

European 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
Journal 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.

Determining the leading-order contact term in neutrinoless double β decay
Journal 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 toolkit for twisted chiral superfields
Journal 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
Journal 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

Light- and strange-quark mass dependence of the ρ(770) meson revisited
Journal of High Energy Physics, 2020 Recent lattice data on ππ-scattering phase shifts in the vector-isovector channel, pseudoscalar meson masses and decay constants for strange-quark masses smaller or equal to the physical value allow us to study the strangeness dependence of these ...

Supergravity with mimetic dark matter
European 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.

Chiral power counting of one- and two-body currents in direct detection of dark matter
Physics Letters B, 2015 We present a common chiral power-counting scheme for vector, axial-vector, scalar, and pseudoscalar WIMP–nucleon interactions, and derive all one- and two-body currents up to third order in the chiral expansion.
