A precision measurment of inclusive electron scattering cross sections is carried out at Jefferson Lab in the quasi-elastic region for 4 He, 12 C, 56 Fe and 208 Pb targets. The longitudinal (R L ) and transverse (R...
An understanding of the confinement mechanism in QCD requires a detailed mapping of the spectrum of hybrid mesons.Understanding confinement means understanding the role of gluons and it is in hybrid mesons that the gl...
Recent measurements of nucleon resonance transition form factors with CLAS at Jefferson Lab are discussed. The new data confirm the assertion of the symmetric constituent quark model of the Roper as the first radial e...
