We systematically study the magnetic dipole moments of multiquark states. In this study, the magnetic dipole moments of possible $B^- B^{*-}$, $B^0 B^{*-}$, $B^- B^{*0} $, $B^0 B^{*0}$, $B_s^0 B^{*-}$, $B^- B_s^{*0}$, $B_s^{0} B^{*0}$, $B^0 B_s^{*0}$ and $B^0_s B_s^{*0}$ states are extracted by means of light-cone sum rules. We explore magnetic dipole moments of these states as molecular picture with spin-parity $J^P = 1^+$. The magnetic dipole moments of hadrons include useful information on the distributions of charge and magnetization their inside, which can be used to understand their geometrical shapes and quark-gluon organizations. The results in the present study together with the spectroscopic parameters may elucidate the future theoretical and experimental researches on the characteristics of doubly-bottom tetraquark states.Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

The LHCb collaboration has recently announced the discovery of two hidden-charm pentaquark states with strange quark content, Pcs(4338) and Pcs(4459); its analysis points towards having both hadrons’ isospins equal to zero and spin-parity quantum numbers 12− and 32−, respectively. Herein, we perform a systematical investigation of the qqscc¯(q=u,d) system by means of a chiral quark model, along with a highly accurate computational method, the Gaussian expansion approach combined with the complex scaling technique. baryon-meson configurations in both singlet- and hidden-color channels are considered. The Pcs(4338) and Pcs(4459) signals can be well identified as molecular bound states with dominant components ΛJ/ψ(60%) and ΞcD(23%) for the lowest-energy case and ΞcD∗(72%) for the highest-energy one. In addition, it seems that some narrow resonances can also be found in each allowed I(JP) channel in the energy region of 4.6–5.5 GeV, except for the 1(12−) channel where a shallow bound state with dominant Ξc∗D∗ structure is obtained at 4673 MeV with binding energy EB=−3 MeV. These exotic states are expected to be confirmed in future high-energy experiments.

The LHCb collaboration has recently announced the discovery of two hidden-charm pentaquark states with also strange quark content, Pcs(4338) and Pcs(4459); its analysis points towards having both hadrons isospin equal to zero and spin-parity quantum numbers 1 2 − and 3 2 − , respectively. We perform herein a systematical investigation of the qqscc (q = u, d) system by means of a chiral quark model, along with a highly accurate computational method, the Gaussian expansion approach combined with the complex-scaling technique. Baryon-meson configurations in both singletand hidden-color channels are considered. The Pcs(4338) and Pcs(4459) signals can be well identified as molecular bound states with dominant components ΛJ/ψ (60%) and ΞcD (23%) for the lowest-energy case and ΞcD * (72%) for the highest-energy one. Besides, it seems that some narrow resonances can be also found in each allowed I(J P )-channel in the energy region of 4.6 − 5.5 GeV, except for the 1( 1 2 − ) where a shallow bound state with dominant Ξ * c D * structure is obtained at 4673 MeV with binding energy EB = −3 MeV. These exotic states are expected to be confirmed in future high energy experiments.
