Light mesons production at the Tevatron to next-to-leading order
  Inclusive production of light mesons ($\pi^0$, $\eta$, $\pi^{\pm}$, $K^{\pm}$ ) at the Tevatron is considered in QCD to next-to-leading order in the formalism of fragmentation functions. We present various distributions of phenomenological interest, along with a new set of $K$ mesons fragmentation functions.
