Free quarks

All searches for free quarks, and fractional electric charges, have been negative. The absence of free quarks has therefore been incorporated into the notion of confinement, which, it is believed, that the theory of quarks must possess. However, it may be possible to change the volume of confinement by creating dense or hot quark matter. These new phases of QCD matter have been predicted theoretically, and experimental searches for them have now started.
