Large \(N\) expansion for strongly-coupled boson-fermion mixtures (Q531314)

The paper states various results for a many-body mixture of an equal number of bosons and two-component fermions with a strong contact interaction. Once the formulation of large \(N\) boson-fermion mixtures is displayed, one switches to composite fermions, and then (this is the core of the paper) one derives a \(1/N\)-expansion of strongly-coupled boson-fermion mixtures. Various conclusions can be drawn from this expansion, and one of them is that there is a strong similarity between boson-fermion mixtures and hadrons.
