Towards studying the structural differences between the pion and its radial excitation
arXiv:2101.11632 · doi:10.1103/PhysRevD.103.094510
Abstract
We present an exploratory lattice QCD investigation of the differences between the valence quark structure of pion and its radial excitation in a fixed finite volume using the leading-twist factorization approach. We present evidences that the first pion excitation in our lattice computation is a single particle state that is likely to be the finite volume realization of . An analysis with reasonable priors result in better estimates of the excited state PDF and the moments, wherein we find evidence that the radial excitation of pion correlates with an almost two-fold increase in the momentum fraction of valence quarks. This proof-of-principle work establishes the viability of future lattice computations incorporating larger operator basis that can resolve the structural changes accompanying hadronic excitation.
