The GMp Experiment which ran in Experimental Hall A at Jefferson Lab as one of the 12 GeV commissioning experiments measured the elastic cross section from electron-proton scattering with 2-3% accuarcy in the Q^2 range from 7 to 16 (GeV/c)^2. Such measurements test our understanding of nucleon structure in terms of Quantum Chromodynamics (QCD), with high-Q^2 , high-precision data providing...

We present a calculation of the pion form factor using overlap fermions on 2+1-flavor domain-wall configurations on a $24^3\times 64$ lattice with $a=0.11 \, {\rm{fm}}$ and on a $32^3 \times 64$ lattice with $a=0.143 \, {\rm{fm}}$ generated by the RBC/UKQCD collaboration. Using the multi-mass algorithm, a simulation has been done with various valence quark masses with a range of space-like...

In 2008 the Jefferson Laboratory F_pi-2 Collaboration released results for the pion electromagnetic form factor, which they had extracted from pion electro-production data. The measured values for the pion form factor were extracted using the Vanderhagen, Guidal and Laget Regge Model. While agreement betweenthis model and data is impressive, the theoretical implementation of gauge invariance...

We adopt a chiral nucleon-pion Lagrangian and formulate a Basis Light-Front Quantization approach to solve the resulting light-front Hamiltonian of a nucleon as an eigenvalue problem. We obtain the nucleon mass spectrum and the corresponding light-front wave functions. Based on the light-front wave functions, we calculate the parton distribution functions as well as the elastic electromagnetic...
