Abstract: (APS)
The relation between the pion's quark distribution function, , its light-front wave function, and the elastic charge form factor, , is explored. The square of the leading-twist pion wave function at a special probe scale, , is determined using models and Poincaré covariance from realistic results for . This wave function is then used to compute form factors with the result that the Drell-Yan-West and quark counting relationships are not satisfied. A new relationship between and is proposed.Note:
