Eta and two pion electroproduction with CLAS Original Research Article

We present new measurements of the reactions ep → epη and ep → e′pπ+π− using data from the CLAS detector at Jefferson Laboratory. In the η channel we present a precise measurement of the proton-S11 (1535) coupling over a wider range of Q2 than any previous experiment. In the two-pion channel, the data show resonant structure not visible in previous experiments.
