The measurement of CKM-angle $alpha$ using decays of $B^0_d \ r ightarrow pi^+ pi^- pi^0$

The preliminary study of the decay Bo->3pi to extract the CKM--angle alpha is presented. The theoretical background to the extraction of alpha using the decay Bo->3pi and its advantages over using the decay Bo->2pi are outlined. Studies of the selection of the decays Bo->3pi will be pres...

description The preliminary study of the decay Bo->3pi to extract the CKM--angle alpha is presented. The theoretical background to the extraction of alpha using the decay Bo->3pi and its advantages over using the decay Bo->2pi are outlined. Studies of the selection of the decays Bo->3pi will be presented. In particular, the use of a discriminant variable to suppress background w ill be described. In addition,studies of the extraction of alpha are presented and the possible sensitivity after 1 and 5 years of LHC running are given.
