## 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.
