  "abstract": "We report improved measurements of branching fractions for charmless hadronic two-body {\\it B} meson decays containing an $\\omega$ meson in the final state. The results are based on a data sample of 78 fb$^{-1}$ collected on the $\\Upsilon(4S)$ resonance by the Belle detector. We measure the branching fractions ${\\mathcal B}(B^+ \\to \\omega K^+) = (6.5^{+1.3}_{-1.2}\\pm 0.6)\\times 10^{-6}$ and ${\\mathcal B}(B^+ \\to \\omega \\pi^+) = (5.7^{+1.4}_{-1.3}\\pm 0.6)\\times 10^{-6}.$ We give 90% confidence upper limits for ${\\mathcal B}(B^0 \\to \\omega K^0) < 7.6\\times 10^{-6}$ and ${\\mathcal B}(B^0 \\to \\omega \\pi^0) < 1.9\\times 10^{-6}.$ We also obtain the partial rate asymmetries ${\\mathcal A}_{CP}=0.06^{+0.21}_{-0.18}\\pm 0.01$ for $B^\\pm \\to \\omega K^\\pm$ and ${\\mathcal A}_{CP}=0.50^{+0.23}_{-0.20}\\pm 0.02$ for $B^\\pm \\to \\omega \\pi^\\pm.$",
