DESCRIPTION:Pavel Meshcheriakov (MIPT Moscow)\nWe study the spectrum of me
 son masses in large N_c QCD_2 governed by the renowned ‘t Hooft integra
 l equation. In [https://arxiv.org/abs/2409.11324] we generalize non-pertu
 rbative analytical methods proposed by Fateev\, Lukyanov and Zamolodchikov
  to the case of arbitrary\, but equal quark masses m_1 = m_2. Furthermore\
 , we have also successfully solved the most general case of the 't Hooft m
 odel with two flavors\, allowing for arbitrary m_{1}\, m_{2} (this paper i
 s being prepared for publication). Our results include analytical express
 ions for spectral sums and systematic large-n expansion. Additionally\, we
  examine the behavior of these non-perturbative results in various limitin
 g regimes\, including the chiral\, heavy-quark\, and heavy-light limits\,
  and establish their full consistency with known analytical and numerical
  results obtained through other approaches.
