Evidence for the exclusive decay Bc±→J/ψπ± and measurement of the mass of the Bc± mesonAbulencia, A.Cuevas, JavierGómez, GervasioGómez-Ceballos, GuillelmoPalencia, EnriquePiedra, JonatanRodrigo Anoro, TeresaRuiz Jimeno, AlbertoScodellaro, LucaVila, IvánVilar Cortabitarte, R.CDF Collaborationddc:500.2et al.We report the first evidence for a fully reconstructed decay mode of the Bc± meson in the channel Bc±→J/ψπ±, with J/ψ→μ+μ-. The analysis is based on an integrated luminosity of 360 pb-1 in pp¯ collisions at 1.96 TeV center of mass energy collected by the Collider Detector at Fermilab. We observe 14.6±4.6 signal events with a background of 7.1±0.9 events, and a fit to the J/ψπ± mass spectrum yields a Bc± mass of 6285.7±5.3(stat)±1.2(syst) MeV/c2. The probability of a peak of this magnitude occurring by random fluctuation in the search region is estimated as 0.012%.This work was supported by the U.S. Department of Energy and the National Science Foundation, the Italian Istituto Nazionale di Fisica Nucleare, the Ministry of Education, Culture, Sports, Science and Technology of Japan, the Natural Sciences and Engineering Research Council of Canada, the National Science Council of the Republic of China, the Swiss National Science Foundation, the A.
