Lets say we have a process where:
Particle B(P) -> v(p2) + k
some particle effectively goes to an antifermion and a photon, with momentums P, p2, and k.
And the diagram is just straightforward, in arrow to vertex, out photon and out antifermion from vertex.
Now the arrow on the antifermion points inward, but that's for fermion/particle number right? Momentum conservation would still be P = p2+k correct? not P +p2 = k (Arrows).
