Abstract
We present a search for B decays to charmless final states involving charged or neutral a(0) mesons. The data sample corresponds to 89x10(6) B(B) over bar pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy B Factory at Stanford Linear Accelerator Center. We find no significant signals and determine the following 90% C.L. upper limits: B(B-0-->a(0)(-)pi(+))<5.1x10(-6), B(B-0-->a(0)(-)K(+))<2.1x10(-6), B(B--->a(0)(-)(K) over bar (0))<3.9x10(-6), B(B+-->a(0)(0)pi(+))<5.8x10(-6), B(B+-->a(0)(0)K(+))<2.5x10(-6), and B(B-0-->a(0)(0)K(0))<7.8x10(-6), where in all cases B indicates the product of branching fractions for B-->a(0)X and a(0)-->etapi, where X indicates K or pi.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
