EPJ Web of Conferences, 2016 In this work pion and kaon condensation in the framework of chiral perturbation theory is studied. I consider a system at vanishing temperature with nonzero isospin chemical potential and strangeness chemical potential; meson masses and mixing in the ...

Pion form factor at very large $Q^2$ [PDF]
arXiv, 2007 The pion form factor at very large $Q^2$ is obtained by using a new pion wave function. It shows that when $Q^2>>(1.8GeV)^2$ the pion form factor reaches the asymptotic limit ${\alpha_s(Q^2)\over Q^2}$

The width of the Δ-resonance at two loop order in baryon chiral perturbation theory
Physics Letters B, 2016 We calculate the width of the delta resonance at leading two-loop order in baryon chiral perturbation theory. This gives a correlation between the leading pion–nucleon–delta and pion–delta couplings, which is relevant for the analysis of pion–nucleon ...

Nonperturbative partonic quasidistributions of the pion from chiral quark models
Physics Letters B, 2017 We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the Nambu–Jona-Lasinio model and the Spectral Quark Model.

Sigma terms in Pion Weak-production near Threshold by Charged Current
EPJ Web of Conferences, 2012 We investigated pion production by charged weak current, which comprises vector and axial vector current. In particular, the contribution by the axial vector current is detailed at the pion threshold in terms of multipole amplitudes, which are useful ...
