Looking forDsJ*mesons inBmeson decays

Abstract
We propose that the search of the BDsJ*M decays, M=D, π, and K, can discriminate the different theoretical postulations for the nature of the recently observed DsJ* mesons. The ratio of the branching ratios B(BDsJ*M)/B(BDs(*)M)1 (0.1) supports that the DsJ* mesons are quark-antiquark (multiquark) bound states. The Belle measurement of the BDsJ*D branching ratios seems to indicate an unconventional picture.
