Observation of the doubly charmed baryon

LHCb collaboration, R. Aaij, B. Adeva +805

A highly significant structure is observed in the mass spectrum, where the baryon is reconstructed in the decay mode . The structure is consi…

Prompt and nonprompt J/ production and nuclear modification in Pb collisions at TeV

LHCb collaboration, R. Aaij, B. Adeva +806

The production of J/ mesons is studied in proton-lead collisions at the centre-of-mass energy per nucleon pair TeV with the LHCb detector at the LHC…

Study of prompt D meson production in pPb collisions at =5 TeV

LHCb collaboration, R. Aaij, B. Adeva +807

Production of prompt D mesons is studied in proton-lead and lead-proton collisions recorded at the LHCb detector at the LHC. The data sample corresponds to an integrated lumino…
