A proton is comprised of two ups and a down quark of color red green and blue. When two protons are slammed together under pressure (in a star), how do those two protons "stick" together? Does the green quark in one proton combine using the strong force with the blue and red quark from the other proton? After the slamming together of two protons does one always decay to a neutron or do some of the proton proton combinations just break apart?
Secondly, the charm quark was found by locating a charm/anti-charm quark pair at 3.11 GeV. How can this be if the charm/anti-charm pair only add up to 2.54 GeV?
