Double Photoproduction off the Proton at CLAS
S. Chandavar, J. T. Goetz, K. Hicks +124
The (1500) meson resonance is one of several contenders to have significant mixing with the lightest glueball. This resonance is well established from several previous experim…
Measurement of the beam asymmetry and the target asymmetry in the photoproduction of mesons off the proton using CLAS at Jefferson Laboratory
P. Roy, Z. Akbar, S. Park +143
The photoproduction of mesons off the proton has been studied in the reaction using the CEBAF Large Acceptance Spectrometer (CLAS) and the frozen-spin target (FROS…
Spin dependence of η meson production in proton-proton collisions close to threshold
P. Adlarson, W. Augustyniak, W. Bardan +88
Taking advantage of the high acceptance and axial symmetry of the WASA-at-COSY detector, and the high degree of the polarized proton beam of COSY, the reaction pp{\to} ppη has been…
Importance of d-wave contributions in the charge symmetry breaking reaction
