We present our recent results on antiheavy-antiheavy-light-light tetraquark systems using lattice QCD. Our study of the b̄b̄us four-quark system with quantum numbers JP = 1+ and the b̄c̄ud four-quark systems with I(JP) = 0(0+) and I(JP) = 0(1+) utilizes scattering operators at the sink to improve the extraction of the low-lying energy levels. We found a bound state for b̄b̄us with Ebind, b̄b̄us = (-86 ± 22 ± 10) MeV, but no indication for a bound state in both b̄c̄ud channels. Moreover, we show preliminary results for b̄b̄ud with I(JP) = 0(1+), where we used scattering operators both at the sink and the source. We found a bound state and determined its infinite-volume binding energy with a scattering analysis, resulting in Ebind, b̄b̄ud = (-103 ± 8) MeV. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).Note
