Editing Charm quark (section)

=== Production and decay ===
Particles containing charm quarks can be produced via electron–positron collisions or in hadron collisions.{{sfn|Gersabeck|2014|pp=3–4}} Using different energies, electron–positron colliders can produce psi or [[upsilon meson|upsilon]] mesons.{{sfn|Gersabeck|2014|p=3}} Hadron colliders produce particles that contain charm quarks at a higher [[Cross section (physics)|cross section]].{{efn|According to [[Mark Thomson (physicist)|Mark Thomson]], a ''cross section'' in particle physics is a measure of quantum mechanical probability for the interaction.{{sfn|Thomson|2013|p=26}} It is the ratio between the interaction rate per target particle and the incident particle flux.{{sfn|Thomson|2013|p=69}}}}{{sfn|Gersabeck|2014|p=4}} The [[W boson]] can also decay into hadrons containing the charm quark or the charm antiquark.{{sfn|Thomson|2013|p=412}} The Z boson can decay into [[charmonium]] through charm quark fragmentation.{{sfn|Braaten|Cheung|Yuan|1993}} The Higgs boson can also decay to {{subatomic particle|J/Psi}} or {{subatomic particle|charmed eta}} through the same mechanism. The decay rate of the Higgs boson into charmonium is "governed by the charm-quark [[Yukawa coupling]]".{{sfn|Han|Leibovich|Ma|Tan|2022}}

The charm quark can decay into other quarks via weak decays.{{sfn|Gersabeck|2014|p=2}} The charm quark also annihilates with the charm antiquark during the decays of ground-state charmonium mesons.{{sfn|Gersabeck|2014|p=2}}
