Abstract

We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter dependent parton Distributions.

Highlights

1 Introduction It is well-known that the usual parton distributions (PDFs) can give the longitudinal information of hadron targets in the deep inelastic scattering (DIS) processes
To obtain the information how PDF are distributed in position space, one can take Fourier transform of Vλλ w.r.t. the transverse momenta p⊥ and p⊥, which gives the so-called Impact Parameter dependent parton Distributions (IPDs) [3]
We introduce a Gaussian form wave packet in initial and final states, G(p⊥, 1/σ2) = exp(−p2⊥σ2/2)

Summary

Introduction

1 Introduction It is well-known that the usual parton distributions (PDFs) can give the longitudinal information of hadron targets in the deep inelastic scattering (DIS) processes. To investigate the transverse information, the generalized parton distributions (GPDs) could be a powerful tool [1]. A Light-Front Constituent Quark Model (LFCQM) is employed to study the GPDs [2] of the ρ meson (spin-1) and its Impact Parameter dependent parton Distributions (IPDs) [3].
