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.9 p.application/pdfengcc-by (c) LHCb Collaboration et al., 2016http://creativecommons.org/licenses/by/3.0/esMesons (Física nuclear)Massa (Física)Mesons (Nuclear physics)Mass (Physics)info:eu-repo/semantics/article669729info:eu-repo/semantics/openAccess
