One question that lingers is that protons carry a positive charge and neutrons have, well a "neutral" charge. As I understand, the neutrinos do not carry a positive charge (or they'd be easier to detect, right?).
So what happens to the positive charge from the proton? Or is the charge simply a property of the up/down quark combination and does not exist in and of itself?

When the two protons fuse, one is transformed to a neutron via the
weak nuclear force. This reaction also release a
positron and an electron neutrino. The positron carries away the positive charge of one of the protons.
Have a look at the
Proton-Proton Chain Reaction for a full description.
