Detailed experimental studies of the decays and interactions of light mesons, such as pi0, eta and omega, are highly needed as precision tests for theoretical models. Such studies allow for extractions of parameters describing decay dynamics as well as transition form factors. Experimental results in this area can also provide measurements of symmetry breaking processes, test the...

85. Meson photoproduction from the nucleon at CLAS

Dr Dan Watts

An extensive measurement programme of meson photoproduction from the nucleon has been obtained exploiting the CLAS detector in Hall-B of Jefferson Lab. The main aim of the programme is to provide high quality experimental data to constrain partial-wave analyses and reaction models used to determine the spectrum and properties of nucleon resonances. Obtaining accurate and detailed information...

Thee mechanisms of light scalar meson production in the D_s+\to s\bar s e+\nu\to [\sigma(600)+f0(980)] e+\nu\to\pi+\pi-e+\nu decays are compared with the mechanisms of light pseudoscalar meson production in the D_s+\to s\bar s e+\nu\to (\eta/\eta') e+\nu decays. It is shown that the s\bar s\to\sigma(600) transition is negligibly small in comparison with the s\bar s\to f_0(980) one. As...
