Lattice QCD study of heavy-heavy-light-light tetraquark candidates
Antje Peters ; Pedro Bicudo ; Luka Leskovec ; Stefan Meinel ; Marc Wagner ;
Date 1 Sep 2016
AbstractWe investigate heavy-light four-quark systems $udar b ar b$ with bottom quarks of finite mass which are treated in the framework of NRQCD. We focus on $I(J^P)=0(1^+)$, where we recently found evidence for the existence of a tetraquark state using static bottom quarks. Furthermore, we report on an investigation of the $u ar d b ar b$ four-quark system with quantum numbers $I(J^P)=1(1^+)$ again using static bottom quarks.
