We investigate heavy-light four-quark systems udbˉbˉ 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 udˉbbˉ four-quark system with quantum numbers I(JP)=1(1+) again using static bottom quarks.
