Say, in a collision, do the quarks need to first hadronize to pions? Or is there a probability that they can hadronize directly to heavier particles like the charm quarks.(quark-anti-quark pair)
The idea I have is that if some kinetic energy is given to a quark, it can move away from another quark, and that elongates the 'gluon tube' and the energy contained by this tube can couple to other particles like pions,etc.
Is that the only way for heavier particles to be produced? Or can the quarks interact with each other individually to produce heavier quarks.
