On the quark structure of the f0(980) meson and the VEPP-2M experimental results for the phi-->pi0pi0gamma decay
It is shown that VEPP-2M results for the 00 decay are consistent with a (mostly) s content for the f0(980), provided we take into account the effects of the UA(1) breaking in the scalar sector. ©...

Final state interference effects in hadronic charm meson decays
In this work two final-state interference effects in hadronic charm meson decays are analyzed. These effects can be observed in the Dalitz plot of the decay under study. In particular, the effects of ...

We present evidence of the observation of the centrally produced phiphi system at 800 GeV/c in the reaction pp-->pslow(phiphi)pfast. A clear bump is observed over low phiK+K– and K+K–K+K– background. Statistics are comparable to those previously obtained in pi–p interactions, where three 2++ waves were found to comprise all cross section. ©2000 American Institute of Physics.
