No, it's an anti-neutrino and an electron colliding with a proton to
produce a neutron (the inverse of beta decay). But an electron
approaching a proton interacts via the EM field and a photon will be
emitted - yet, in the beta decay no photon need be absorbed. I think
it's an example of the radiation arrow of time making a time-reversed
process impossible - or maybe just vanishingly improbable. Bruce Kellet
has written a paper about these problems, see pp 35.

Retro causation solves the EPR problem (i.e. provides a local

Stenger's book "Timeless Quantum" in which he uses this kind of
explanation to good effect. The problem is that some things, like the
radiation arrow of time and inverse beta decay seem hard to fit in.
Price has done extensive work on the radiation arrow, but I haven't
read it for a while and can't recall offhand what conclusions he
Is inverse beta decay an example of T-symmetry breaking, like neutral
kaon decay (IIRC) ? If so, it won't fit into his scheme!
