I have read these questions:
And it made me curious.
I understand that quarks can only be found in confinement, and that gluons create flux tubes, if we want to separate them. When we want to separate quarks, the energy needed will not decrease with distance, but will remain constant and after a while it will be enough to create new quarks.
But I did not find anything about gluons, can we find free gluons? Is that what a gluon ball is? Can we find those free?
- Can we find free gluons (at normal energy levels)? Can we find free gluon balls?
