BaBar: sin(2beta+gamma)
The time-dependent CP asymmetries in fully reconstructed B{sup 0} {yields} D{sup (*){+-}}{pi}{sup {-+}}/{rho}{sup {-+}} decays (new preliminary result), and in partially reconstructed B{sup 0} {yields} D{sup (*){+-}}{pi}{sup {-+}} decays, are measured with the BABAR detector at the PEP-II asymmetric B factory at SLAC, using 232 million {Upsilon}(4S) {yields} B{bar B} decays. We combine the above results and, using other measurements and theoretical assumptions, they interpret them in terms of the angles of the unitarity triangle describing the Cabibbo-Kobayashi-Maskawa matrix. They find |sin(2{beta} + {gamma})| > 0.64(0.42) at 68%(90%) confidence level using a frequentistic approach and |2{beta}+ {gamma}| = (90 {+-} 43){sup o} using a Bayesian approach.
