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…
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…
Dramatic implications of unitarity for meson spectroscopy
George Rupp, Eef van Beveren
An unambiguous definition of meson resonance masses requires a description of the associated phase shifts in terms of a manifestly unitary -matrix and its complex poles. However…
Dimuon enhancement at 28 GeV and tentative (pseudo)scalar partner of the Z boson at 57.5 GeV
Eef van Beveren, George Rupp
The CMS Collaboration at the LHC recently reported an accumulation of data around 28 GeV in the invariant-mass distribution of muon pairs in association with a b quark jet and at l…
Scalar mesons: fifty years of challenging the quark model
George Rupp, Eef van Beveren
Half a century of work on the light scalar mesons , , , and is briefly reviewed. After summarising all light scalar candidates in the…
General unquenching properties of two-meson scattering and production amplitudes
Eef van Beveren, George Rupp
Besides the unitarity and symmetry requirements for a multi-resonance scattering amplitude, several other natural conditions can easily exclude unrealistic proposals. In particular…
