NNLO positivity bounds on chiral perturbation theory for a general number of flavours
Journal of High Energy Physics, 2022 We present positivity bounds, derived from the principles of analyticity, unitarity and crossing symmetry, that constrain the low-energy constants of chiral perturbation theory. Bounds are produced for 2, 3 or more flavours in meson-meson scattering with

T-duality transformation of gauged linear sigma model with F-term
Nuclear Physics B, 2014 We develop the duality transformation rules in two-dimensional theories in the superfield formalism. Even if the chiral superfield which we dualize involves an F-term, we can dualize it by virtue of the property of chiral superfields.

Precision calculation of the axion-nucleon coupling in chiral perturbation theory
Journal of High Energy Physics, 2020 We derive the axion-nucleon interaction Lagrangian in heavy baryon chiral perturbation theory up to next-to-next-to-leading order. The effective axion-nucleon coupling is calculated to a few percent accuracy.

Two-meson form factors in unitarized chiral perturbation theory
Journal of High Energy Physics, 2021 We present a comprehensive analysis of form factors for two light pseudoscalar mesons induced by scalar, vector, and tensor quark operators. The theoretical framework is based on a combination of unitarized chiral perturbation theory and dispersion ...

Massive Spinning Relativistic Particle: Revisited under BRST and Supervariable Approaches
Advances in High Energy Physics, 2020 We discuss the continuous and infinitesimal gauge, supergauge, reparameterization, nilpotent Becchi-Rouet-Stora-Tyutin (BRST), and anti-BRST symmetries and derive corresponding nilpotent charges for the one 0+1-dimensional (1D) massive model of a ...

Two-current correlations in the pion on the lattice
Journal of High Energy Physics, 2018 We perform a systematic study of the correlation functions of two quark currents in a pion using lattice QCD. We obtain good signals for all but one of the relevant Wick contractions of quark fields.
