Abstract
We report on a search for the process B+→K¯¯¯*0(892)K+ using 232×106 Υ(4S)→BB¯¯¯ decays collected with the BABAR detector at the PEP-II asymmetric-energy B factory at SLAC. From a signal yield of 25±13[stat]±7[syst] B+→K¯¯¯*0(892)(→K−π+)K+ events, we place an upper limit on the branching fraction B(B+→K¯¯¯*0(892)K+) of 1.1×10−6, at the 90% confidence level.| File | Dimensione | Formato | |
