Search for B+c decays to the ppπ+ final state Badalov, Alexey Garrido Beltrán, Lluís Gascón Fora, David Graciani Díaz, Ricardo Graugés Pous, Eugeni Marin Benito, Carla Picatoste Olloqui, Eduardo Rives Molina, Vicente José LHCb Collaboration Mesons (Física nuclear) Massa (Física) Mesons (Nuclear physics) Mass (Physics) A search for the decays of the B+ c meson to pp¯π+ is performed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. 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. 2018-02-26T12:06:46Z 2018-02-26T12:06:46Z 2016-06-01 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://hdl.handle.net/2445/120257 669729 eng Reproducció del document publicat a: https://doi.org/10.1016/j.physletb.2016.05.074 Physics Letters B, 2016, vol. 759, p. 313-321 https://doi.org/10.1016/j.physletb.2016.05.074 cc-by (c) LHCb Collaboration et al., 2016 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess 9 p. application/pdf Elsevier Articles publicats en revistes (Física Quàntica i Astrofísica)
