Beauty-full Tetraquarks

Abstract

In this article we present a calculation of the $bb\bar{b}\bar{b}$ 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 $18.69\pm 0.03~\mbox{GeV}$, which is around 100 MeV below twice the ${\eta }_b$ mass. This bound state can behave as a four-lepton resonance via its decay to ${\rm Y}(1S){\rm Y}(1S{)}^{\ast }\to {\ell }^{+}{\ell }^{-}{\ell }^{+}{\ell }^{-}$.
