Search for the rare decay B+ -> a0+pi0

الأصل · EN

A search for the decay B+ -> a0+pi0 with the a0+ decaying to an eta and a pi+ was carried out at the Stanford Linear Accelerator Center using the BABAR detector coupled with the PEP-II collider. The analysis used a data sample comprised of approximately 252 million BBbar pairs collected at the Upsilon(4S) resonance. No signal was observed and a 90% confidence level upper limit on the branching fraction was set at 1.32 x 10⁻⁶.
