The positivity of the integrand of certain Euclidean space functional integrals implies that the free energy per unit volume for QCD with a baryon chemical potential μB (and zero isospin chemical potential) is greater than the free energy with isospin chemical potential μᵢ = (2 μB)/Nc (and zero baryon chemical potential). This relation implies a bound on the nucleon mass: there exists a particle X in QCD such that Mₙ ≥ (Nc mₓ)/(2 Iₓ) where mₓ is the mass and of the particle and Iₓ is its isospin.
