Description
The latest measurements of $K^{\pm}$ multiplicities in semi-inclusive deep-inelastic scattering from the COMPASS experiment at CERN are presented. The data were collected using a $160$ $GeV$ muon beam incident on an isoscalar $^{6}LiD$ target. The large statistics collected cover a wide kinematic range and the results are presented in 3-dimensional bins of $x_{Bjorken}$, $y$, and $z$. These measurements are sensitive to both the strange quark distribution function $s(x)$ and to the strange quark fragmentation functions. They will serve as inputs to global QCD fits to constrain quark fragmentation functions.
