Fragmentation functions are typically parametrised exploiting measurements performed in $\mathrm{e^+e^-}$ and $\mathrm{ep}$ collisions, under the assumption of universality across collision systems. Measurements of charm-hadron yields in…

Fragmentation functions are one of the key components of the factorisation theorem used to calculate heavy-flavour hadron production cross sections. The non-perturbative nature of fragmentation functions necessitates that they are…
