Description
The LHCb experiment has the unique possibility, among the LHC experiments, to be operated in fixed-target mode using its internal gas target. The energy scale achievable at the LHC and the excellent detector capabilities for vertexing, tracking and particle identification allow a wealth of novel measurements of great interest for cosmic ray physics. In particular, using a helium target, the first measurement of antiproton production in proton-helium collisions was achieved using a 6.5 TeV proton beam, for antiproton energies in the range 12-110 GeV. The results are particularly relevant to the interpretation of the recent precise measurements of the antiproton flux in cosmic rays.
