Abstrakt

We propose novel bosonic Technicolor models augmented by an $SU(2)_R$ gauge group and scalar doublet. Dynamical breaking of $SU(2)_R$ induced by technifermion condensation triggers $SU(2)_L$ breaking via a portal coupling. The scale of the new strong interactions is as high as that of composite Higgs models, and the vacuum stability challenge confronting ordinary bosonic Technicolor models is avoided. Thermal or asymmetric dark matter, whose stability is ensured by a $U(1)_{\rm TB}$ technibaryon symmetry, can be realized. In the latter case, the correct relic density can be reproduced for a wide range of dark matter mass via leptogenesis.
