The authors present results for measurement of the decays to charmless final states of B{sup 0} meson to {eta}K{sup 0}, {eta}{omega}, a{sub 1}{sup +}(1260){pi}{sup -} with a{sub 1}{sup +}(1260) {yields} {pi}{sup +}{pi}{sup +}{pi}{sup -}, and of B{sup +} to {eta}{rho}{sup +}, {eta}{prime}{pi}{sup +}. Analyses are based on data taken with the BABAR detector at the PEP-II asymmetric e{sup +}e{sup -} collider at SLAC.

An upper limit has been extracted, at the 90% C.L, for the rare charmless hadronic B meson decay B ± → a0(980)±[pi]0, where a0(980)± →[eta][pi]± and [eta]→[gamma][gamma] or [eta]→ [pi]+[pi]-[pi]0. The analysis was based on a sample of approximately 340.7 fb-1 of data taken at the (4S) resonance with the BABAR detector at the PEP-II e+e- collider at SLAC from May 1999 to August 2006. The sample contains (379.9 ± 4.2) million B$\bar{B}$ pairs.

We present preliminary results of searches for charged B mesons decaying into the charmless three-body final states h[sup[+-]] h[sup[-+]] h[sup[+-]], where h=[pi] or K, using 51.5 fb[sup -1] of data collected at the[Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. No assumptions are made about intermediate resonances. We measure the branching fractions[Beta](B[sup[+-]][yields] K[sup[+-]][pi][sup[-+]][pi][sup[+-]])= (59.2[+-] 4.7[+-] 4.9) x 10[sup -6] and[Beta](B[sup[+-]][yields] K[sup[+-]] K[sup[-+]] K[sup[+-]])= (34.7[+-] 2.0[+-] 1.8) x 10[sup -6], where the first error is statistical and the second error is systematic. In the same study, we do not observe significant signals for the final states B[sup[+-]][yields][pi][sup[+-]][pi][sup[-+]][pi][sup[+-]] and B[sup[+-]][yields] K[sup[+-]] K[sup[-+]][pi][sup[+-]], and therefore provide the 90% confidence upper limits[Beta](B[sup[+-]][yields][pi][sup[+-]][pi][sup[-+]][pi][sup[+-]])
