## Constraint from

There are two ways to access the value of , which allows one to remove the ambiguity between and that comes from the measurement of :
• From the time dependent analysis of the decay it is possible to extract the values of both and using the angular analysis of the Vector-Vector final state.
• Using the same Dalitz approach of the DK measurement of , it is possible to measure from decays (up to a ambiguity) from the interference of the and decay amplitudes, as suggested in hep-ph/0503174.
The experimental values we use are summarized in the Table of Inputs. The representation of this constraint in the plane is given below.
