Original: Example of hadrons containing charm quarks include the J \/O/ meson, D mesons, charmed Sigma baryons, and other charmed particles.
Simplified: Similar to up quarks, charm quarks have a charge of +2 \/O/ 3. Although charm quarks are not extremely common, they can be found in particles created by particle accelerators (which smash atoms together at extremely high speeds), such as J \/O/ Ï mesons, D mesons, and other charmed particles.
