Generalized parton distributions of pion for non-zero skewness in AdS/QCD
Nuclear Physics B, 2018 We study the generalized parton distributions (GPDs) of pion for non-zero skewness by considering the leading |qq¯〉 Fock state component. Inspired from AdS/QCD light-front wave functions, we calculate the pion GPDs.

Evaluation of the Axial Vector Commutator Sum Rule for Pion-Pion Scattering
, 2007 We consider the sum rule proposed by one of us (SLA), obtained by taking the expectation value of an axial vector commutator in a state with one pion. The sum rule relates the pion decay constant to integrals of pion-pion cross sections, with one pion ...

Vector form factor of the pion : A model-independent approach [PDF]
, 2002 We study a model-independent parameterization of the vector pion form factor that arises from the constraints of analyticity and unitarity. Our description should be suitable up to s^(1/2) ~ 1.2 GeV and allows a model-independent determination of the ...

The investigation of K+π−, π+K− and π+π− atoms
EPJ Web of Conferences, 2016 Theory, using Low Energy QCD, predicts with high precision the pion-pion and pion-kaon scattering lengths. There is accurate relation between K+π− and π+K− atoms lifetime and pion-kaon S-wave scattering lengths with isospin 1/2 and 3/2.

Pion wave-function as a bound system in 3 + 1 dimensional QCD
Results in Physics, 2017 We investigate the Bethe-Salpeter-like amplitude in 3 + 1 dimensions. This involves a system comprising a quark and an antiquark combined by gauge fields to satisfy gauge invariance. We derive the equation of motion for this system and construct a series

Coupled channels calculation of a pion-Lambda-nucleon quasibound state
, 2010 We extend the study of a JP=2+, I=3/2 pion-Lambda-nucleon quasibound state [Phys. Rev. D 78, 014013 (2008)] by solving nonrelativistic Faddeev equations, using 3S1-3D1, Lambda N - Sigma N coupled channels Chiral Quark Model local interactions, and pion ...

Flavour Breaking Effects of Wilson twisted mass fermions [PDF]
, 2005 We study the flavour breaking effects appearing in the Wilson twisted mass formulation of lattice QCD. In this quenched study, we focus on the mass splitting between the neutral and the charged pion, determining the neutral pion mass with a stochastic ...

, 2006 The mean field (MF) approximation for the pion matter, being equivalent to the leading ChPT order, involves no dynamical loops and, if self-consistent, produces finite renormalizations only.
