A search for the narrow structure, X(5568), reported by the D0 Collaboration in the decay sequence X→B_{s}^{0}π^{±}, B_{s}^{0}→J/ψϕ, is presented. The analysis is based on a data sample recorded with the ATLAS detector at the LHC corresponding to 4.9  fb^{-1} of pp collisions at 7 TeV and 19.5  fb^{-1} at 8 TeV. No significant signal was found. Upper limits on the number of signal events, with properties corresponding to those reported by D0, and on the X production rate relative to B_{s}^{0…

We study the weak decays of exotic tetraquark states $${b\bar{c}}{q\bar{q}}$$bc¯qq¯ with two heavy quarks. Under the SU(3) symmetry for light quarks, these tetraquarks can be classified into an octet

Inspired by the newly observed $X_{0}(2900)$ and $X_1(2900)$ at LHCb, the $K^*\bar{D}^*$ and $K\bar{D}_1$ interactions are proposed in the qBSE approach combined with the one-boson-exchange

In this work we systematically calculate the mass spectra of open charm and bottom tetraquarks $qq\overline{q}\overline{Q}$ within an extended relativized quark model. The four-body relativized

### Lattice investigation of exotic tetraquark channels

• Physics
• 2020
We perform an $n_f=2+1$ lattice study of a number of channels where past claims exist in the literature for the existence of strong-interaction-stable light-heavy tetraquarks. We find no evidence for

### Are there narrow flavor-exotic tetraquarks in large- Nc QCD?

• Physics
Physical Review D
• 2018
A salient feature shared by all tetraquark candidates observed in experiment is the absence of flavor-exotic states of the type $\bar a b\bar c d$, with four different quark flavors. This phenomenon

The exotic state X(5568) which was observed by D0 Collaboration is very likely to be a tetraquark state with four different valence quark flavors, though the existence was not confirmed by other

The present data imply that $\phi(2170)$ may not be an excited state of $\phi$, but is a four quark state with $ss\bar s \bar s$ constituents. Furthermore, there are no two mesons of $s\bar s$
