Description
We analyze the scale-invariant extension of the standard model (SM) with a strongly interacting
hidden sector by using AdS/QCD. Using AdS/QCD, we can reduce the number of input parameters
to three, i.e., hidden pion decay constant, hidden pion mass and tan β that is defined as the ratio
of the vaccum expectation values of the singlet scalar field and the SM Higgs boson. As a result,
our model has sharp predictibility. We perform the phenomenological analysis of the hidden pions,
that is the dark matter (DM) candidates in the model. With various theoretical and experimental
constraints we search for the allowed parameter space and find that both resonance and nonresonance
solutions are possible. Some typical correlations among various observables such as relic
denstiy, Higgs signal strength and DM-nucleon cross section are scrutinzed. We provide some
benchmark points for experimental tests.
