The Gpd Experimental Program at Jefferson Lab
Recent results on the Generalized Parton Distribution (GPD) program at Jefferson Lab (JLab) will be presented. The emphasis will be in the Hall A program aiming at measuring Q−dependences of different terms of the Deeply Virtual Compton Scattering (DVCS) cross section. This is a fundamental step before one can extract GPD information from JLab DVCS data. The upcoming program in Hall A, using bo...
متن کاملThe N * Physics Program at Jefferson Lab
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 excitation of the nucleon. The data on high Q nπ production better constrain the branching ratios βNπ and βNη for the S11(1535). For the first time, the longitudinal transition ampl...
متن کاملAn Electron-Ion Collider at Jefferson lab
As explained in the oral presentation [1], the original plans for an electron-ion collider (ELIC) at Jefferson Lab involved the construction of two figure-of-eight rings, intersecting at up to four collision points, with a proton energy of 30-225 GeV (30-100 GeV/A for ions up to Pb) and electrons (and positrons) from 3 to 9 GeV [2]. Since the construction of such a facility must await completio...
متن کاملThe N Program at Jefferson Lab - Status and Prospects
pion production, and the excitation of the lowest negative parity state N− 1/2 (1535) is studied in the pη and in the Nπ channels. First results on electroproduction of pππ show intriguing resonance structure which seems difficult to explain using known baryon resonance properties. Searches for resonances in KY ∗ and in pω channels also reveal resonance-like behavior. I also briefly address a n...
