Understanding the and masses as well as their widths
Eef van Beveren, George Rupp
The low and approximately equal masses of the scalar mesons and , as well as their relatively small decay widths, are impossible to understand in terms of stan…
Modern meson spectroscopy: the fundamental role of unitarity
Eef van Beveren, George Rupp
The importance of -matrix unitarity in realistic meson spectroscopy is reviewed, both its historical development and more recent applications. First the effects of imposing -…
Strong evidence of from a unitary multichannel reanalysis of elastic scattering data with crossing-symmetry constraints
N. Hammoud, R. Kamiński, V. Nazari +1
An analysis is presented of elastic -wave phase shifts and inelasticities up to 2 GeV, aimed at identifying the corresponding excited resonances and foc…
and : possible surprises in the Standard Model
Eef van Beveren, George Rupp
With the reported observation of the Higgs boson at the LHC, the Standard Model of particle physics seems to be complete now as for its particle content. However, several experimen…
