Query: Measurements of CKM Angle Beta from BABAR   We present recent results of hadronic B meson decays related to the CKM angle
beta. The data used were collected by the BABAR detector at the pepII
asymmetric-energy e+e- collider operating at the Upsilon(4S) resonance located
at the Stanford Linear Accelerator Center.
