Search for a Charged Partner of the X (3872) in the B Meson Decay B to X- K, X- to J/psi pi- pi0
- SLAC
The authors search for a charged partner of the X(3872) in the decay B {yields} X{sup -}K, X{sup -} {yields} J/{psi}{pi}{sup -} {pi}{sup 0}, using 234 million B{bar B} events collected at the {Upsilon}(4S) resonance with the BABAR detector at the PEP-II e{sup +}e{sup -} asymmetric-energy storage ring. The resulting product branching fraction upper limits are {Beta}(B{sup 0} {yields} X{sup -}K{sup +}, X{sup -} {yields} J/{psi}{pi}{sup -}{pi}{sup 0}) < 5.4 x 10{sup -6} and {Beta}(B{sup -} {yields} X{sup -} {bar K}{sup 0}, X{sup -} {yields} J{psi}{pi}{sup -}{pi}{sup 0}) < 22 x 10{sup -6} at the 90% confidence level.
