The f(1)(1285) meson withmass 1281.0 +/- 0.8MeV/c(2) and width 18.4 +/- 1.4MeV (full width at half maximum) was measured for the first time in photoproduction from a proton target using CLAS at Jefferson Lab. Differential cross sections...
New results on the single-differential and fully integrated cross sections for the process gamma(upsilon)p -> p'pi(+)pi(-) are presented. The experimental data were collected with the CLAS detector at Jefferson Laboratory. Measurements...
Short-range correlated (SRC) nucleon pairs are a vital part of the nucleus, accounting for almost all nucleons with momentum greater than the Fermi momentum (k(F)). A fundamental characteristic of SRC pairs is having large relative...
Beam-target double-spin asymmetries and target single-spin asymmetries in exclusive pi(+) and quasiexclusive pi(-) electroproduction were obtained from scattering of 1.6- to 5.7-GeV longitudinally polarized electrons from longitudinally...
