Rev.

Under the flavor SU(3) symmetry, we obtain the total branching fraction $BR [\\overline B^0 \\to (\\overline K^0K^+\\pi^-+K^0K^-\\pi^+)]=(7.17^{+0.50+1.97+0.08}_{-0.53-1.42-0.07})\\times 10^{-6}$, which is in agreement with the recent measurements of BaBar and LHCb within errors. For the decay $\\overline B^0 \\to \\overline K^0K^+\\pi^-$, the nonresonant background and $a_0^+(1450)$ pole in the current-induced process provide large contribution, the latter of which has not been included in previous studies. On the contrary,the decay $\\overline B^0 \\to K^0K^-\\pi^+$ is dominated by the nonresonant background and the offshell $\\rho^-$ pole. When the flavor SU(3) symmetry breaking and the final-state rescattering are considered under two different scenarios, the results can also accommodate the experimental data with large uncertainties. Moreover, the direct $CP$ asymmetry of $\\overline B^0 \\to \\overline K^0K^+\\pi^-$ is found to be sensitive to the matrix element of scalar density. These predictions could be further tested in the LHCb experiment or Super-b factory in future.", "revisions": [ { "version": "v2", "updated": "2014-05-06T12:34:25.000Z" } ], "analyses": { "subjects": [ "13.25.Hw", "13.20.He" ], "keywords": [ "factorization approach", "comprehensive study", "flavor su", "nonresonant background", "super-b factory" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2014, "month": "May", "volume": 89, "number": 9, "pages": "094007" }, "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1282438, "adsabs": "2014PhRvD..89i4007L" } } }
