The Pion Light-Cone Wave Function Phipi on the lattice: a partonic signal?
Abstract
We determine the conditions required to study the pion light-cone wave function Phipi with a new method: a direct display of the partons constituting the pion. We present the preliminary results of a lattice computation of Phipi following this direction. An auxiliary scalar-quark is introduced. The spectroscopy of its bound states is studied. We observe some indications of a partonic behavior of the system of this scalar-quark and the anti-quark.
