We investigate heavy-light four-quark systems udb b with bottom quarks of finite mass which are treated in the framework of NRQCD. We focus on I(JP) = 0(1+), where we recently found evidence for the existence of a tetraquark state using static bottom quarks. Furthermore, we report on an investigation of the u dbb four-quark system with quantum numbers I(JP) = 1(1+) again using static bottom quarks.
