Doubly Charmed Tetraquark $T_{cc}^{+}$ from Lattice QCD near Physical Point

Yan Lyu, Sinya Aoki, Takumi Doi +3

The doubly charmed tetraquark $T_{cc}^{+}$ recently discovered by the LHCb Collaboration is studied on the basis of $(2+1)$-flavor lattice QCD simulations of the $D^{\ast }D$ system with n…
