摘要：

We report the ground state masses of hadrons containing at least one charm and one bottom quark using lattice quantum chromodynamics. These include mesons with spin (J) and parity (P), (J(P)): 0(-), 1(-), 1(+), and 0(+) and the spin 1/2 and 3/2 baryons. Among these hadrons, only the ground state of 0(-) is known experimentally, and therefore our predictions provide important information for the experimental discovery of all other hadrons with these quark contents.
