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,in the antiproton energy range 12-110 GeV/c. The results are
particularly relevant to the interpretation of the recent accurate
measurements of the antiproton content in cosmic rays.
