Polynomial duality-symmetric lagrangians for free p-forms
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]
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 ...

Chiral Lagrangians and the QCD string [PDF]
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 ...

Chiral Lagrangian for excited pions [PDF]
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.

Universal scale factors relating mesonic fields and quark operators [PDF]
Scale factor matrices relating mesonic fields in chiral Lagrangians and quark-level operators of QCD sum-rules are shown to be constrained by chiral symmetry, resulting in universal scale factors for each chiral nonet.

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

Supergravity with mimetic dark matter
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.

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