| dc.description | We show how the linear "low-density theorem" of Drukarev and Levin can be extended to arbitrary positive integer power of the baryon density $ρ$. The n^th coefficient in the McLaurin expansion of the fermion condensate's $ρ$ dependence is the connected n-nucleon sigma term matrix element. We calculate the $O(ρ^2)$ coefficient in lowest-order perturbative approximation to the linear sigma model and then show how this and other terms can be iterated to arbitrarily high order. Convergence radius of the result is discussed. | |
