Heavy Flavoured Meson Fragmentation Functions in $e^{+}{e}^{-}$ annihilation up to NNLO + NNLL

Leonardo Bonino, Matteo Cacciari, Giovanni Stagnitto

In this contribution, we make use of the QCD perturbative fragmentation function formalism to describe the one-particle inclusive fragmentation of a heavy quark produced in $e^+e^-…
