Is it possible to produce images of pair production in home-made cloud chamber?
Basics
You need to
be able to generate a pair-creation event and
be able to image it well enough to know what it was.
Getting a pair conversion event
Pair creation calls for the highest energy …

Pair production of neutrinos
There is no tree level vertex for a neutrino scattering off of a photon, so you have two choices:
Weak Drell-Yan if the progenitors are leptons. That is $$l + \bar{l} \to Z^0 \to \nu + \bar{\nu} \,. …

momentum conservation in particle-antiparticle creation
Being "near by" means that there is (unavoidably) an interaction between them.
The problem is no longer
$$ \gamma \to e^+ + e^- \,,$$
but
$$ \gamma + A \to e^+ + e^- + A\,,$$
(here $A$ represents th …
