Quark counting, Drell-Yan West, and the pion wave function

https://doi.org/10.1103/PhysRevC.110.L042201

Alberg, Mary; Miller, Gerald A (October 2024, Physical Review C)

The relation between the pion's quark distribution function, $q (x)$ , its light-front wave function, and the elastic charge form factor, $F (Δ^{2})$ , is explored. The square of the leading-twist pion wave function at a special probe scale, $ζ_{H}$ , is determined using models and Poincaré covariance from realistic results for $q (x)$ . 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 $q (x)$ and $F (Δ^{2})$ is proposed. Published by the American Physical Society2024
