A study of semi-inclusive charmless decays
We study semi-inclusive charmless decays in detail, such as
, , , where does not contain a charm (anti)quark. We find that
the process () can be particularly
useful for determination of the CKM matrix element . We calculate and
present the branching ratio (BR) of as a function of
, with an estimate of possible uncertainties. It is expected that the
BR is an order of . Our estimation indicates that one can
phenomenologically determine with reasonable accuracy by measuring
the BR of ().Comment: 18 pages, 7 figures; Revtex; version accepted for publication in Eur.
