I've got my physics mock next week and rereading through the textbook I came across the Feynman diagrams for positron decay and the proton - antineutrino interaction, and what confuses me is the fact that the W+ can decay into a positron and neutrino, yet the positron can be formed by a W+ colliding with an antineutrino. Does this mean that either neutrinos or antineutrinos have negative rest mass energy?

The W boson is an exchange particle within the process.
The proton-antineutrino interaction goes as followed:
Proton+ antineutrino -- W+--> Beta+ and a neutron.
As the proton loses its positive charge, hence W+, a neutron is produced.
The neutron-neutrino interaction goes as followed:
Neutron+ neutrino --W- --> proton and B- decay.
The neutron gives up exchange particle, hence(-) and is negative, why the proton is produced.
