Abstract
The and
production ratios are measured by the LHCb detector from
of
collisions delivered by the LHC at
TeV and
at
TeV. Both ratios are presented as a function of transverse momentum,
, and rapidity,
, in the ranges
and
. Results at the two energies are in good agreement as a function of rapidity loss,
, and are consistent with previous measurements. The ratio
, measuring the transport of baryon number from the collision into the detector, is smaller in data than predicted in simulation, particularly at high rapidity. The ratio
, measuring the baryon-to-meson suppression in strange quark hadronisation, is significantly larger than expected.
