„Measurement of the cross-section ratio \u03c3(\u03c8(2S)) \/ \u03c3(J\/\u03c8(1S)) in exclusive photoproduction at HERA.<\/strong>” <\/p>\n\n\n\n Referuje: dr hab. Grzegorz Grzelak<\/p>\n\n\n\n Abstract:<\/p>\n\n\n\n During the seminar I will present new analysis performed with ZEUS data on exclusive vector meson photoproduction – measurement of the cross section ratio of two charmonia states: \u03c8(2S) and J\/\u03c8(1S). The analysis was performed using muonic decay channels of the investigated vector mesons.<\/p>\n\n\n\n The ratio of their production cross sections has been measured as a function of W (photon\u2013proton centre-of-mass energy) and |t| (squared four-momentum transfer at the proton vertex) and compared to previous data in photoproduction and deep inelastic scattering and with predictions of QCD-inspired models of exclusive vector-meson production.<\/p>\n\n\n\n Serdecznie zapraszamy<\/p>\n\n\n\n dr hab.
