Measurement of J/ψ production cross-sections in pp collisions at 13 TeV. At the EPS-HEP 2015 conference in Vienna the LHCb collaboration has presented today the first measurement of the probability…
Observation of particles composed of five quarks, pentaquark-charmonium states, seen in Λb0 → J/ψpK- decays
The LHCb collaboration submitted today a paper based on run 1 data which reports the observation of pentaquark-charmonium states decaying into a J/ψ meson and a proton p. In the…
