We derive, in particular, an important constraint on the masses of the $(t_L, b_L)$ partners, which does not depend on the flavor structure of the sector beyond the SM. This bound is obtained from the \"infrared\" contribution to $b \\to s\\gamma$ induced by the flavor-conserving effective vertex $Wt_Rb_R$.
