Resonances at finite temperature from the lattice

Jakob Hoffmann, Peter Lowdon, Owe Philipsen

The properties of hadronic resonances at finite temperature constitute an important probe of the thermal QCD medium. In this work we use the concept of thermoparticles, which chara…

Binding energy of the $T_{bb}$ tetraquark from lattice QCD with relativistic and nonrelativistic heavy-quark actions

Jakob Hoffmann, Stefan Meinel

We present a new determination of the $b ˉ b ˉ u d$ ( $J^{P} = 1^{+}$ , $I = 0$ ) tetraquark binding energy using lattice QCD with domain-wall light quarks and a nonperturbatively tuned…

Prediction of an $I (J^{P}) = 0 (1^{-})$ $b ˉ b ˉ u d$ Tetraquark Resonance Close to the $B^{} B^{}$ Threshold Using Lattice QCD Potentials

Jakob Hoffmann, Marc Wagner

We use antistatic-antistatic potentials computed with lattice QCD and a coupled-channel Born-Oppenheimer approach to explore the existence of a $b ˉ b ˉ u d$ tetraquark res…

$b ˉ b ˉ u d$ 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…
