State of the art spectroscopy of (un)physical gauge degrees of freedom using numerical experiments KU Leuven
The protons and neutrons which are constituting our atomic nuclei are themselves composed of quarks. The latter particles interact very strongly via the exchange of gluons, in fact so strong that it is quasi impossible to separate them from the neutrons and protons. One way this works out is at extremely high temperatures (~100000 times the temperature of the Sun’s interior, itself a nuclear fusion reactor). Such circumstances were present in ...
