Description
We consider a strongly interacting fermionic matter that is in direct interaction with the fermionic dark matter via the exchange of Standard Model Higgs boson. Invoking quasi-particle description for strongly interacting fermions with dynamic quasi-particle excitations we evaluate the thermodynamic properties of this matter in relativistic mean-field approximation. Taking into consideration Boltzmann transport equations in relaxation time approximation we evaluate the transport properties of this medium. It is found that due to the coupling of fermionic quasi-particle excitations and Higgs boson ζ/s can get singular near transition region both along O(4) transition line and in Z(2)
universality class.
