We study tetraquark resonances with lattice QCD potentials computed for a static bbar bbar pair in the presence of two lighter quarks u d, the Born-Oppenheimer approximation and the emergent wave method. As a proof of concept we focus on the system with isospin I = 0, but consider different relative angular momenta l of the heavy quarks bbar bbar. For l=0 a bound state has already been predicted with quantum numbers I(JP) = 0(1+). Exploring various angular momenta we now compute the phase…

Bottomonium resonances with I=0 from lattice QCD correlation functions with static and light quarks

We discuss, how to study $I = 0$ quarkonium resonances decaying into pairs of heavy-light mesons using static potentials from lattice QCD. These static potentials can be obtained from a set of

Lattice QCD investigation of a doubly-bottom b¯b¯ud tetraquark with quantum numbers I(JP)=0(1+)

We use lattice QCD to investigate the spectrum of the $\bar{b} \bar{b} u d$ four-quark system with quantum numbers $I(J^P) = 0(1^+)$. We use five different gauge-link ensembles with $2+1$ flavors of

Searching for beauty-fully bound tetraquarks using lattice nonrelativistic QCD

Determination of ΛMS¯(nf=2) and analytic parametrization of the static quark-antiquark potential

While lattice QCD allows for reliable results at small momentum transfers (large quark separations), perturbative QCD is restricted to large momentum transfers (small quark separations). The latter

Lattice QCD is a very important tool used by particle physicists to investigate the properties of baryons and mesons. Lattice techniques are presently being employed to understand and elucidate the

Lattice Prediction for Deeply Bound Doubly Heavy Tetraquarks.

Motivated by observations from heavy baryon phenomenology, two lattice interpolating operators are considered, both of which are expected to couple efficiently to tetraquark states: one with a diquark-antidiquark and a meson-meson structure.

Including heavy spin effects in the prediction of a $\bar{b} \bar{b} u d$ tetraquark with lattice QCD potentials

We investigate spin effects in four-quark systems consisting of two heavy antibottom quarks and two light up/down quarks. To this end, we use the Born-Oppenheimer approximation. We utilize potentials

Stability of dimesons.

It is proved that, for sufficiently large quark mass m, and fixed antiquark mass, the dimeson (Q/sup 2/q-bar /sup 2/) must be stable against strong decay into two mesons, and systems in which Q is c or b are studied, using the many-body confining interaction that comes from a Born-Oppenheimer approximation to the MIT bag model.
