Experiment Overview¶
The pion occupies a special place in nature as one of the lightest hadrons, with one valence quark, and one valence antiquark. Small as it might be, the pion is also responsible for the long range character of the strong interaction that binds the atomic nucleus together. If chiral symmetry (left-right symmetry of rules governing strong interactions) were an exact global symmetry of strong interactions then pions would be massless. Through gluon-quark interaction and by explicit inclusion of light quark masses, chiral symmetry of massless QCD undergoes explicit symmetry breaking, thus giving the pion its mass. This puts the pion at the core of the mechanism that dynamically generates all the mass of the hadrons and makes it a crucial element in understanding hadron structure. E12-07-105 and E12-06-101 joint experiment allows for the measurement of the pion longitudinal and transverse separated cross section and pion form factor respectively at the highest Q 2 achievable at a 12 GeV Jefferson Lab. Carrying out this experiment at high values of Q2 can allow us to study nonperturbative dynamics of QCD wile also searching for a transition to the perturbative regime. In addition, the data obtained will provide us with information important in understanding reaction mechanisms and a benchmark for the models used to calculate the structure of light hadrons.
