Abstract
The LHCb experiment has distinctive features, providing novel
possibilities for production measurements needed to improve the
interpretation of cosmic ray observations in the space or through
atmospheric showers.
In particular, LHCb 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, the different
available nuclear targets and the excellent
detector capabilities for vertexing, tracking and particle
identification offer unique opportunities. 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.
