Title: A $$$$bb{\bar{b}}{\bar{b}}$$$$ di-bottomonium at the LHC?

Abstract

We study the case of a di-bottomonium $$bb\bar{b}$$$$\bar{b}$$ par-ticle at the LHC. Its mass and decay width are obtained within a new model of diquark–antidiquark interactions in tetraquarks. The same model solves several open problems on the phenomenology of the experimentally better known X, Z states. We show that the $$bb\bar{b}$$$$\bar{b}$$ tetraquark is expected approximately 100 MeV below threshold, and compare to a recent analysis by LHCb seeking it in the Yμμ final state.

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

Complementary aspects of potential and quark models for BB and B anti B systems

Conference Dover, C B

Our topic at this Round Table is the connection between the particle physics (quark model) and nuclear physics (potential model) approaches to baryonium. This question is part of a larger problem which arises in a variety of contexts in strong interaction physics: how does one reconcile the success of meson (and baryon) exchange models for many low energy hadron-hadron scattering processes with the structure of the underlying quark model. This general problem is discussed, using as examples: (1) baryon-baryon (BB) and baryon-nucleus (specifically N, ..lambda.., ..sigma.., and XI) interactions; and (2) baryon-antibaryon (B anti B) systems and their coupling tomore »« less

Masses of doubly heavy tetraquarks with error bars

Journal Article Braaten, Eric ; He, Li-Ping ; Mohapatra, Abhishek - Physical Review D

In the heavy-quark limit, the two heavy quarks in a doubly heavy baryon or a doubly heavy tetraquark are bound by their color-Coulomb potential into a compact diquark. The doubly heavy hadrons are related by the approximate heavy-quark–diquark symmetry of QCD to the heavy hadrons obtained by replacing the heavy diquark by a heavy antiquark. Effective field theories can be used to expand the masses of singly heavy hadrons and doubly heavy hadrons in inverse powers of the heavy-quark masses. The coefficients in the expansions for doubly heavy tetraquarks can be determined from those for heavy mesons, heavy baryons, and doubly heavy baryons using heavy-quark–diquark symmetry. We predict the masses of the ground-state doubly heavy tetraquarks with error bars using as inputs the masses of heavy mesons and heavy baryons measured in experiments and the masses of doubly heavy baryons calculated using lattice QCD. The only doubly heavy tetraquarks predicted to be stable with respect to strong decays are bb tetraquarks with light flavormore »« less
