dc.description.abstract© Springer Nature Switzerland AG 2020.We study a strongly interacting many-fermion system in the unitary limit using an implicit renormalization framework and compute the Bertsch parameter (formula presented) considering only contact interactions. The main ingredient of the calculation is the scale separation between low and high momentum degrees of freedom, which we take as the Fermi momentum (formula presented), and the assumption that the physics below this momentum scale can be re-parametrized into the low energy coefficients of the contact interactions. Once the unitary renormalization conditions are imposed on the two-body scattering amplitude obtained from the contact interactions, we evaluate (formula presented) at leading order (LO), next-to-leading order (NLO) and next-to-next-to-leading order (NNLO).
