I've been doing some reading on QCD, and I keep running into the notion of "massless quarks". Are they massless in the sense that if you look at(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

E = \pm \sqrt{p^2 + m^2}

[/tex]

the [tex]p^2[/tex] term dominates and [tex]E \sim p[/tex] or is this something completely different?
