Brainee Posted May 2, 2023 Share Posted May 2, 2023 When an anti-electron and an anti-quark meet do they annihilate or does it have to be same particle type to annihilate for example an anti-electron and an electron? Link to comment Share on other sites More sharing options...

I meant when anti-electron and a common quark meet do they annihilate or does it have have to be same particle type to annihilate for example an anti-electron and a common electron?

joigus Posted May 3, 2023 Share Posted May 3, 2023 Conservation of charge, baryonic number and leptonic number insist that it be so. There are no quarks with charge +1, lepton number -1, and baryon number 0. Link to comment Share on other sites More sharing options...
