Title: Beauty-full tetraquarks

Abstract

In this article we present a calculation of the tetraquark ground-state energy using a diffusion Monte Carlo method to solve the non-relativistic many-body system. The static potential for the four quark system is chosen to align with the flux-tube picture of QCD. Using this approach, we find that the state has a mass of , which is around 100 MeV below twice the mass. This bound state can behave as a four-lepton resonance via its decay to Υ(1S)Υ(1S)*→ℓ⁺ℓ^-ℓ⁺ℓ^-

Tetraquarks made of sufficiently heavy quarks are bound in QCD

Journal Article Assi, Benoît ; Wagman, Michael L. - TBD

Tetraquarks, bound states composed of two quarks and two antiquarks, have been the subject of intense study but have yet to be understood from first principles. Previous studies of fully-heavy tetraquarks in nonrelativistic effective field theories of quantum chromodynamics (QCD) suggest different conclusions for their existence. We apply variational and Green's function Monte Carlo methods to compute tetraquarks' ground- and excited-state energies in potential nonrelativistic QCD. We robustly demonstrate that fully-heavy tetraquarks are bound in QCD for sufficiently heavy quark masses. We also predict the masses of tetraquark bound states comprised ofmore »« less

We search for the J^PC = 0^{– –} and 1^+– light tetraquark states with masses up to 2.46 GeV/c² in Υ(1S) and Υ(2S) decays with data samples of (102 ± 2) million and (158 ± 4) million events, respectively, collected with the Belle detector. No significant signals are observed in any of the studied production modes, and 90% credibility level (C.L.) upper limits on their branching fractions in Υ(1S) and Υ(2S) decays are obtained. The inclusive branching fractions of the Υ(1S) and Υ(2S) decays into final states with f₁(1285) are measured to be B(Υ(1S) → f₁(1285) + anything) = (46more »« less

Masses of tetraquarks with two heavy quarks in the relativistic quark model

Journal Article Ebert, D ; Faustov, R N ; Galkin, V O ; ... - Physical Review. D, Particles Fields

Masses of tetraquarks with two heavy quarks and open charm and bottom are calculated in the framework of the diquark-antidiquark picture in the relativistic quark model. All model parameters were regarded as fixed by previous considerations of various properties of mesons and baryons. The light quarks and diquarks are treated completely relativistically. The c quark is assumed to be heavy enough to make the diquark configurations dominating. The diquarks are considered not to be pointlike but to have an internal structure which is taken into account by the calculated diquark form factor entering the diquark-gluon interaction. It is found thatmore »« less
