N2 - In this article we present a calculation of the bbb¯b¯ 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 0++ state has a mass of 18.69±0.03GeV, which is around 100 MeV below twice the ηb mass. This bound state can behave as a four-lepton resonance via its decay to ϒ(1S)ϒ(1S)⁎→ℓ+ℓ−ℓ+ℓ−.
