[12] Current data implies that, for g2R ≃ g2L, mWR ∼> 800 GeV, with a similar lower bound on an mZ′ [13].

[14] M. Peskin, Nucl. Phys. B175, 197 (1980); J. Preskill, ibid. 177, 21 (1981). The TC theory forms condensates hF¯F i, where F = U a, Da, E, N , but not, e.g., hU¯aEi, hD¯aEi, hU¯aN i, hD¯aN i, hU¯aDai, hE¯N i, or, for NT C = 2, hǫij Fχi T CFχ′j i, χ = L, R. The excluded condensates would incur an energy price due to gauge boson mass generation when the (weaker) gauge symmetries are broken.

[15] A vectorial SU(N ) theory with Nf massless fermions in the fundamental representation is expected to exist in a confining phase with SχSB if Nf < Nf,cond., where Nf,cond. ≃ (2/5)N (50N 2 − 33)/(5N 2 − 3) and in a nonabelian Coulomb phase if Nf,cond. < Nf < 11N/2. For N = 2, we have Nf,cond. ≃ 8.
