500/1-001 - Main Auditorium (CERN)
Description
The BaBar experiment has observed two new Ds states with surprisingly low masses and narrow decay widths.
The D*sJ(2317)+ lies below the DK threshold and decays to Ds+π0.
The DsJ(2458) + lies above the DK threshold and below the D*K threshold and decays to Ds+π0γ. Both of these decays violate isospin conservation. The analyses will be described and results compared with those from other experiments.

Note: Tea & coffee will be served at 16.00 hrs.
