A longstanding problem with the popular Sakai-Sugimoto holographic dual of thermal QCD is that the mesinos, the (nonsupersymmetric) fermionic partners of the mesons, are nearly isospectral with mesons and have an unsuppressed mesino-mesino-meson interaction, both being in contradiction with actual QCD. We solve this problem in a UV complete (and different) type-IIA string dual at intermediate coupling of realistic thermal QCD, in which the mesinos are shown to be much heavier than and noninteracting with mesons (the wave function/mass/interaction terms receiving no -theory corrections). In particular we derive a large- enhancement of the Kaluza-Klein mass scale (from to ) arising from the construction of the type-IIA mirror [1] of the type-IIB dual [2] of thermal QCD-like theories, as well as the generation of a one-parameter family of -independent mass scale at in the -theory uplift [3], wherein the parameter can be made appropriately large. We also show that the mesino-mesino-single-()meson interactions, vanish identically in the aforementioned type-IIA holographic dual.
