I know the PF rules regarding using only peer reviewed texts, but in this case, it's the only source I have access to and I'm not trying to promote the content in any way, really I'm just trying to understand if it is actually saying what it seems to be. https://arxiv.org/pdf/1303.3752 Generally, all the (pop-science) texts I have read suggest that regular hadrons (such as Protons or Neutrons) are comprised simply of 3 quarks and the gluons that 'bind' (for want of a better word) them. I understand at least that there may be a high number of gluons (and generation of more through inputting energies these may result in the "string" qualities observed in some experiments). I am curious, though as to if there is a consideration made in the paper that, with the colour charges balanced and all the available strong force from the gluons, there may be many other quark/antiquarks of colour combinations that effectively cancel out overall, leaving the same (UUD or DDU for example) 'excess'? Is this 'correct'?
