We find that current experimental data can impose some model-independent constraints on the parameter space of direct CP violation in B_d->\\pi^+\\pi^- and B_d->\\pi^0\\pi^0. Furthermore, we establish a direct relationship between the weak phase \\alpha and the charge-averaged branching fractions and CP-violating asymmetries of B->\\pi\\pi decays.", "revisions": [ { "version": "v2", "updated": "2003-09-16T20:56:17.000Z" } ], "analyses": { "subjects": [ "12.15.Ff", "11.30.Er", "13.25.Hw", "14.40.Nd" ], "keywords": [ "direct cp violation", "isospin triangles", "current experimental data", "fresh isospin analysis", "decay modes" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
