# The fragmentation function of $K^{*0}$ particle?

Where can I find the fragmentation function (FF) of $K^{*0}(892)$ particle?
The online FF generator doesn't give the option of $K^{*0}$

Are you sure that the K* has a fragmentation function? I'm pretty sure that, since it is a resonance, it doesn't fragment but simply decay isotropically according to the usual matrix elements. What are you looking for it?

Oops, sorry for my ambiguity. Actually I mean the quarks fragment into hadrons, i.e. the fragmentation function is $D^{q\to h}$ with $h = K^{*0}(892)$, and $q = u,d,s,c,\cdots$.
For $h = pion, kaon...$, it is available(given by online FF generator), but what about $K^{*0}$?
