Making use of chiral SU(4) ⊗ SU(4) and scale-symmetry breaking together with ɛ saturation we obtain limits for the charmed-pseudoscalar-meson masses. These limits only allow charmed (C=+/-1) pseudoscalar states with masses below 2.5 GeV. The existence of such states with masses above 1.5 GeV would imply strong restrictions on the theory: δ has at least dimension lδ=1, u has at least dimension lu=2 and the ɛ mass is higher than the upper limit noted in the Particle Data Group table. If the masses of these states are above 2 GeV, it furthermore follows than lu=3 and lδ=2. Assuming the Gaillard-Lee-Rosner relation between the masses of the vector mesons and the quarks, identification of the ψ(3.1) with the φc implies lu=3, lδ=2, mɛ~0.92 GeV, Γɛ~0.42 GeV, and mD=2.2 GeV. We have assumed integer dimensions. We have furthermore assumed that the effective mɛ is not much above 0.9 GeV.
