Revisiting quark-hadron duality for heavy meson non-leptonic decays in two-dimensional QCD

Hiroyuki Umeeda

We study lifetimes of heavy mesons in the 't Hooft model, a large- $N_{c}$ theory of strong interaction in two-dimensional spacetime. Since this model is solvable, one can evaluate th…

Quark-hadron duality for heavy meson mixings in the 't Hooft model

Hiroyuki Umeeda

We study local quark-hadron duality and its violation for the $D^{0} - D ˉ^{0}$ , $B_{d}^{0} - B ˉ_{d}^{0}$ and $B_{s}^{0} - B ˉ_{s}^{0}$ mixings in the 't Hooft model, offering a laboratory to t…
