WebSep 4, 2014 · A positron would annihilate with the electron, but not with the neutron per se. NB: you could argue that an electron or a positron is somewhat like a quark, but it isn't actually a quark. No, i chose "neutron with positron" because i didnt want to be confusing with "proton and positron", which both start with "p". A positron is an anti-electron. WebA few of the weak interactions make sense. An electron and a positron can annihilate to form a Z boson. Similarly, any standard model fermion and its antiparticle can annihilate to form a Z. An electron and an electron anti-neutrino can annihilate to form a W. Similarly, and lepton and the appropriate anti-neutrino can annihilate to form a W. clinton housing development corporation
