A pion-driven near-threshold enhancement in the $π T_{cc}$ system

Pedro Brandão, Jorgivan Morais Dias, Luciano M. Abreu

Hadronic molecules are commonly viewed as products of near-threshold two-body dynamics. We investigate whether an experimentally established molecule can also serve as a building b…
