Nice background :).

The problem is that none of these papers deal with the interactions
between mirror matter and normal matter. According to eq.(5) of
http://de.arXiv.org/abs/hep-ph/0308254, the high atomic weight (and to
less extent the high energy detection threshold) of the detectors of
most experiments (e.g. Edelweiss) would not detect either H' or He',
although Edelweiss could detect O'.

So their parameter space plots are invalid for mirror matter: they
ignore the physics of detection.

Anyway, i've put some more details on the twiki:


including a short fortran script.

Of course, we cannot claim the result as definite without a lot more
convergence of independent experiments, preferably by independent groups of

This is the challenge to see if we can think of an independent experiment.
E.g. something in stellar physics.
