Fragmentation of charm to charmonium in $${{\varvec{e}}}^+{{\varvec{e}}}^-$$ e+e- and $${{\varvec{pp}}}$$ pp collisions
Abstract We perform numerical comparison of the fragmentation mechanism of charmonium production ($$g\,g\rightarrow c\,{\bar{c}}$$ gg→cc¯ followed by $$c\rightarrow \psi \,c$$ c→ψc ) with the full leading order calculation ($$g\,g\rightarrow \psi \,c\,{\bar{c}}$$ gg→ψcc¯ at $${{\mathcal {O}}}(\alpha...
