Abstract Using relativistic quantum mechanics. we study the spectrum of a non-BPS two-particle bound state in the massive phase of N $$ \mathcal{N} $$ = 4 super Yang-Mills. in the limit when one of the particles is infinitely heavier than the other. We find that the spectrum shows the exact n 2 degeneracy for each principal quantum number n. https://www.ealisboa.com/best-offer-Duraflex-Circuit-Widebody-Fender-Flares-Fiberglass-Infiniti-G35-Coupe-Non-Sport-super-save/
