Resummed quarkonium fragmentation functions are derived to all orders in perturbation theory, resolving threshold singularities without nonperturbative model functions.
[44], we know that the double UV pole arises from the diagram where an additional virtual gluon is exchanged between the timelike and lightlike Wilson lines
