Abstract
We search for a charged partner of the X(3872) in the decay B-->X-K, X--->J/psipi(-)pi(0), using 234x10(6) B (B) over bar events collected at the Y(4S) resonance with the BABAR detector at the PEP-II e(+)e(-) asymmetric-energy storage ring. The resulting product branching fraction upper limits are B(B-0-->X-K+,X--->J/psipi(-)pi(0))<5.4x10(-6) and B(B--->X-(K) over bar (0),X--->J/psipi(-)pi(0))<22x10(-6) at the 90% confidence level.File in questo prodotto:
