Hadronic B decays

Charged and neutral B mesons are copiously produced in the decays of the Y(4s) resonance. Hadronic B decays provide a rich field of studies in CP violation, CKM Matrix elements, QCD and search for new physics.  This physics is accessible with  CLEO, a multipurpose detector at the electron-positron collider CESR. CP violation is one necessary ingredient to explain the dominance of matter over anti-matter in the universe and thus to explain our very existence. First signs of CP violation in the B system are being observed at the B factories but the extraction of fundamental parameters might prove difficult since many decay channels have to be measured to understand effects like final state interactions, rescattering and interference between dominant and suppressed decay amplitudes. I investigatED color-suppressed B decays into a D and a light meson. The observation of B to D0 pi0 decays have now been observed for the first time. The analysis has been published in Physical Revue Letters. The paper has already been cited several times.
The measurement of B0b to D0 pi0 allows us to study final state interactions via an isospin analysis of B to D pi. To improve our sensitivity, we updated the CLEO measurements of the color-favored B to D pi decays. New results with improved statistics and systematics have been accepted by Physical Review D (Rapid Communication).
