Role of left-hand cut contributions on pole extractions from lattice data: Case study for $T_{cc}(3875{)}^{+}$

Meng-Lin Du, Arseniy Filin, Vadim Baru +7

We discuss recent lattice data for the $T_{cc}(3875{)}^{+}$ state to stress, for the first time, a potentially strong impact of left-hand cuts from the one-pion exchange on the pole ex…
