Offshell photon lightcone wave functions of odd chirality in the effective lowenergy theory
Abstract
The Lorentz decomposition of the lightcone distribution amplitudes is carried out up to twist four. The WandzuraWilczeklike relations associated with the transverse photon wave function are derived in the same way as for the rho meson. The onshell and offshell photon wave functions with odd chirality at the leading twist in the effective lowenergy theory derived from the instanton vacuum of QCD are calculated. The explicit expression of the transverse photon wave function, {phi}{sub {gamma}}{sub perpendicular}(u,P{sup 2}), is worked out, and the twisttwo parts of the other two photon wave functions, h{sub {gamma}}{sub parallel}{sup (s),twisttwo}(u,P{sup 2}) and h{sub {gamma}}{sub parallel}{sup (t),twisttwo}(u,P{sup 2}), are calculated based on the WandzuraWilczeklike relations. The dependence of the coupling f{sub {gamma}}{sup perpendicular}(P{sup 2}) and the lightcone photon wave functions with respect to the virtuality, P{sup 2}, are analyzed, and the endpoint behavior as well as the middlepoint behavior of the photon wave functions is discussed.

The leading and highertwist distribution amplitudes and lightcone wave functions of real and virtual photons are analyzed in chiral quark models. The calculations are performed in the nonlocal quark model based on the instanton picture of the QCD vacuum, as well as in the spectral quark model and the NambuJonaLasinio model with the PauliVillars regulator, which both treat interaction of quarks with external fields locally. We find that in all considered models the leadingtwist distribution amplitudes of the real photon defined at the quarkmodel momentum scale are constant or remarkably close to the constant in the x variable, thus aremore »

Smallx behavior of lightcone wave functions in transverse lattice gauge theory
We study the behavior of lightcone wave functions, in coarse transverse lattice gauge theory, when one or more parton lightcone momenta are small. This probes the limit of hadron structure at large and small Bjorken x. Finiteenergy boundary conditions on boundstates allow one to derive the analytic form of wave functions in this region. This leads to simple, universal predictions for the behavior of quark generalized parton distributions near their endpoints. For the first few meson wave functions at large N{sub c}, we give the simplest ansatz that incorporates all the boundary conditions. 
Meanfield theory of confined particles; Offmassshell aspects of relativistic wave functions
The authors study nonlinear equations in two variables which arise in a theory of nontopological solitons. For simplicity, we limit our considerations to a relativistic meanfield description of two scalar particles which form a bound state. They present results for a model in which the constituents have a momentumdependent mass whose form is motivated by nonperturbative QCD studies. They discuss the probability distribution of the squared fourmomentum, k{sup 2}, of a particle of momentum k{sub {mu}}. They also introduce a definition of the constituent mass of our particles and comment on the relation of our model to the constituent quarkmore »
