Studies of the η meson with WASA at COSY and KLOE-2 at DAΦNE
Pawel Moskal (for and on behalf of the KLOE-2 and WASA-at-COSY Collaborations)
Sažetak
One of the basic motivations of the KLOE-2 and WASA-at-COSY experiments is the test of fundamental symmetries and the search for phenomena beyond the Standard Model in the hadronic and leptonic decays of ground-state mesons and in particular in decays of the η meson. At COSY these mesons are produced in collisions of proton or deuteron beam with hydrogen or deuterium pellet target, and at DAΦNE η mesons originate from radiative decays of φ meson or from the fusion of virtual gamma quanta exchanged between colliding electrons and positrons. This contribution includes brief description of experimental techniques used by KLOE-2 and WASA-at-COSY as well as some of physics aspects motivating investigations of production and decays of η mesons.
