Standard Model Predictions and New Physics Sensitivity in B->DD Decays

Understand

An extensive model-independent analysis of B->DD decays is carried out employing SU(3) flavour symmetry, including symmetry-breaking corrections.

• Several theoretically clean observables are identified which allow for testing the Standard Model.
• These include the known time-dependent CP asymmetries, the penguin pollution of which can be controlled in this framework, but notably also quasi-isospin relations which are experimentally well accessible and unaffected by symmetry-breaking corrections.
• Theoretical assumptions can be kept to a minimum and controlled by additional sum rules.
