Description
An approximate light-cone wave function for the pion effective quark-antiquark Fock sector corresponding to a small value of the renormalization group parameter $\lambda$ will be presented. This wave function will be used to obtain wave functions of higher pion sectors for larger $\lambda$ by the W-transformation [1].
The approximate wave function is motivated by the LF-holography [2] in harmony with the quadratic confinement potential in the front form of Hamiltonian dynamics [3], and thus also with the linear confining potential in the instant form. The S-wave and P-wave contributions to the wave functions will be discussed in the context of the pion diffractive scattering on platinum, using the experimental data of the E791 Experiment [4].
