No signal is found and an upper limit, at 95 confidence level, is set, fc fu × B(B+ c → ppπ+) < 3.6 × 10−8 in the kinematic region m(pp) < 2.85 GeV/c2, pT(B) < 20 GeV/c and 2.0 < y(B) < 4.5, where B is the branching fraction and fc ( fu) is the fragmentation fraction of the b quark into a Bc+ (B+) meson. cc-by (c) LHCb Collaboration et al., 2016 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess Mesons (Física nuclear) Massa (Física) Mesons (Nuclear physics) Mass (Physics) Search for B+c decays to the ppπ+ final state info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
