Model-Independent Observation of Exotic Contributions to B degrees -> J/psi K+pi(-) Decays

Olivier Schneider, Aurelio Bay, Yiming Li, Guido Haefeli, Christoph Frei, Frédéric Blanc, Tatsuya Nakada, Michel De Cian, Elena Graverini, Luca Pescatore

An angular analysis of B degrees -> J/psi K+pi(-) decays is performed, using proton-proton collision data corresponding to an integrated luminosity of 3 fb(-1) collected with the LHCb detector. The m(K+pi(-) ) spectrum is divided into fine bins. In each m( ...
