  "description": "<p>Using the latest LHCb measurements of time-dependent CP violation in the Bs0\u2192K+K\u2212 decay, a U-spin relation between the decay amplitudes of Bs0\u2192K+K\u2212 and B0\u2192\u03c0+\u03c0\u2212 decay processes allows constraints to be placed on the angle \u03b3 of the unitarity triangle and on the Bs0 mixing phase \u22122\u03b2s . Results from an extended approach, which uses additional inputs on B0\u2192\u03c00\u03c00 and B+\u2192\u03c0+\u03c00 decays from other experiments and exploits isospin symmetry, are also presented. The dependence of the results on the maximum allowed amount of U-spin breaking is studied. At 68% probability, the value \u03b3=(63.5\u22126.7+7.2)\u00b0 modulo 180\u00b0 is determined. In an alternative analysis, the value \u22122\u03b2s=\u22120.12\u22120.16+0.14 rad is found. In both measurements, the uncertainties due to U-spin breaking effects up to 50% are included.</p>",
