A new approach to the coupled scalar description (K-Matrix).
- This allow us to model f o(980) on our data in a proper way (unitarity conservation)
trough the Likelihood scan method
- We can obtain an improvement in -2ln L Ds+ p-p+p+ using this model
- Ds+ K-K+ p + seems to prefer a scalar with large tails ( a0(980)? ) instead of the
f o(980) obtained by K-Matrix.
The scan method performed on this decay do not give us any information (no minimum) for f o(980)
Now we can work with a most general approach to Dalitz Plot analyses:
- Arbitrary numbers of amplitudes for the model and bckg (the only limit is the
MINUIT numbers of parameters )
- It allow us to parameterized the bckg in a proper way.
- Extension to D0 should be trivial.
- New Dalitz Plot analysis has been preliminary studied (D+ p-p+p+ and D+ K- p + p + )
