Query: Vector-like technineutron Dark Matter: is a QCD-type Technicolor ruled
  out by XENON100?   We continue to explore a question about the existence of a new strongly
coupled dynamics above the electroweak scale. The latter has been recently
realized in the simplest consistent scenario, the vector-like (or
chiral-symmetric) Technicolor model based upon the gauged linear sigma-model.
One of the predictions of a new strong dynamics in this model, the existence of
stable vector-like technibaryon states at a TeV scale, such that the lightest
neutral one could serve as a Dark Matter candidate. Here, we consider the
QCD-type Technicolor with SU(3)_TC confined group and one SU(2)_W doublet of
vector-like techniquarks and test this model against existing Dark Matter
astrophysics data. We show that the spin-independent Dirac
technineutron-nucleon cross section is by far too large and ruled out by
XENON100 data. We conclude that vector-like techniquark sectors with an odd
group of confinement SU(2n+1)_TC, n=1,2,... and with ordinary vector-like weak
SU(2)_W interactions are excluded if the technibaryon number is conserved. We
discuss a possible generic TC scenario with a technibaryon sector interacting
via an extra vector SU(2)_V other than the standard weak SU(2)_W and consider
immediate implications for the cosmological evolution and freeze out of heavy
relic technineutrons.
