$b ˉ b ˉ u d$ Tetraquarks with $I (J^{P}) = 0 (1^{-})$ and $b ˉ c ˉ u d$ Tetraquarks with $I (J^{P}) = 0 (0^{+})$ and $I (J^{P}) = 0 (1^{+})$ from Lattice QCD Antistatic-Antistatic Potentials

Jakob Hoffmann, Lasse MÃ¼ller, Marc Wagner

We study heavy spin effects in $b ˉ b ˉ u d$ and $b ˉ c ˉ u d$ four-quark systems using the Born-Oppenheimer approximation and existing antistatic-antistatic potentials c…

Computing the topological susceptibility from fixed topology QCD simulations

Arthur Dromard, Wolfgang Bietenholz, Krzysztof Cichy +1

The topological susceptibility is an important quantity in QCD, which can be computed using lattice methods. However, at a fine lattice spacing, or when using high quality chirally…

Definitions of a static SU(2) color triplet potential

Marc Wagner, Owe Philipsen

We discuss possibilities and problems to non-perturbatively define and compute a static color triplet potential in SU(2) gauge theory. Numerical lattice results are presented and c…

Investigation of $B B ˉ$ four-quark systems using lattice QCD

Antje Peters, Pedro Bicudo, Krzysztof Cichy +1

We investigate $B B ˉ$ systems by computing potentials of two static quarks in the presence of two quarks of finite mass using lattice QCD. By solving the SchrÃ¶dinger equation…

$b ˉ b ˉ u d$ and $b ˉ b ˉ u s$ tetraquarks from lattice QCD using symmetric correlation matrices with both local and scattering interpolating operators

Constantia Alexandrou, Jacob Finkenrath, Theodoros Leontiou +3

We study the $b ˉ b ˉ u d$ tetraquark with quantum numbers $I (J^{P}) = 0 (1^{+})$ as well as the $b ˉ b ˉ u s$ tetraquark with quantum numbers $J^{P} = 1^{+}$ using lattice QCD.…

Interpreting Numerical Measurements in Fixed Topological Sectors

Wolfgang Bietenholz, Christopher Czaban, Arthur Dromard +4

For quantum field theories with topological sectors, Monte Carlo simulations on fine lattices tend to be obstructed by an extremely long auto-correlation time with respect to the t…
