The relativistic Schrödinger equation and its application to pseudoscalar meson baryon scattering in a broken SU(3) symmetry model
The problem of pseudosca1ar meson baryon scattering is discussed within the framework of the relativistic Schrodinger equation and in the four lowest partia1 waves. The driving force (potential) is obtained by ca1culating the allowed single particle exchange processes for which thee~oharged …

Field Theoretic Models of Deep Inelastic Lepton-Nucleon Scattering
… functions of ω) in our neutral vector meson ladder model and our pseusoscalar meson model because of the appearance of factors of ln|q<sup>2</sup>|. We also find the neutrino-nucleon structure functions in analogous ladder models and they exhibit the same non-scaling behavior. In all …

Off-shell pion electromagnetic form factors in chiral perturbation theory
… contributions to Green functions in the pseudoscalar meson sector. We find that in addition to the phenomenological constant 'L₉' associated with the pion charge radius, another phenomenological constant enters the electromagnetic form factor ƒπ⁺. This constant scales a contribution that …

Static and dynamic properties of the pion from continuum modelling of strong QCD
… propagator Schwinger-Dyson equation (SDE) and pseudoscalar meson Bethe-Salpeter equation (BSE) at and beyond the rainbow-ladder truncation level of this system of equations. We solve this coupled system of integral equations using a phenomenological model for the dressed gluon propagator in …

Isospin Violating Hadronic Mass Splittings using Lattice QCD+QED
… light ground state hadron spectrum, including pseudoscalar mesons, octet baryons and decuplet baryons. We replicate this same analysis for ground state charmed hadrons. In these studies the QED component is necessary for two reasons. Firstly, it is necessary when attempting to obtain mass …

Measurement of Pion-Pion Final State Interactions in η → π +π −γ with CLAS at Jefferson Lab
<p>Decays of pseudoscalar mesons proceed from the chiral anomaly, which arises from spontaneous chiral symmetry breaking. In the limit of massless quarks (chiral limit), the η → π +π −γ the decay width is determined solely by the box anomaly term in the Wess Zumino Witten Lagrangian. Since the …
