Even-meson mass-vanishing conjecture. Under analytic continuation $\alpha\to\alpha^*_k$, the spectrum contains a pair of mesons whose masses vanish according to

Infrared CFT conjecture. Following Fateev, each of these points corresponds to a critical point in the infrared, whose dynamics are governed by a non-trivial conformal field theory…

Let $calpha$ and $cbeta$ be the large parameters appearing in the phase expansion $cPhi^{(k)}_{\pm}$, and let $k\geq 1$. In the special case $calpha=cbeta$, the leading terms in th…

In the large-$N$ massless 't Hooft limit of $QCD$, consider the meson spectrum, with its states organized by their squared masses. Exact linearity conjecture. The meson spectrum sh…
