“…Then the mass splitting between the high and low mass mixed states is estimated to be about 150 MeV. To explain the strong de- cay properties of the D * J (2600) and/or D s1 (2700), configuration mixing between 2 3 S 1 and 1 3 D 1 is also suggested in the literature [81][82][83][84][85]. Thus, the 2 3 S 1 -1 3 D 1 mixing might also exist in the B and B s meson families.…”

Stimulated by the exciting progress in experiments, we carry out a combined analysis of the masses, and strong and radiative decay properties of the B and B s -meson states up to the second orbital excitations. Based on our good descriptions of the mass and decay properties for the low-lying well-established states B 1 (5721), B * 2 (5747), B s1 (5830) and B * s2 (5840), we give our quark model classifications for the high mass resonances observed in recent years. It is found that (i) the B J (5840) resonance may be explained as the low mass mixed state B(|S D L ) via 2 3 S 1 -1 3 D 1 mixing, or interpreted as the 2S -wave state B(2 1 S 0 ). (ii) The B J (5970) resonance may be assigned as the 1 3 D 3 state in the B meson family. (iii) The narrow structure around 6064 MeV observed in the B + K − mass spectrum at LHCb may be mainly caused by the B sJ (6109) resonance decaying into B * + K − , and favors the assignment of the high mass 1D-wave mixed state B s (1D ′2 ) with J P = 2 − . (iv) The relatively broader B sJ (6114) structure observed at LHCb may be explained with the mixed state B s (|S D H ) via 2 3 S 1 -1 3 D 1 mixing. Most of the missing 1P-, 1D-, and 2S -wave B-and B s -meson states have a relatively narrow width, they are most likely to be observed in their dominant decay channels with a larger data sample at LHCb.

“…The mixing angle for the charmed sector is φ ≃ −(36 ± 6) • , while that for charmed-strange sector is φ = (−54 ± 7) • . To explain the strong decay properties of the D * 1 (2600) and/or D * s1 (2700), configuration mixing between 2 3 S 1 and 1 3 D 1 is also suggested in the literature [37,38,41,42,50,51,62,81]. In this work we restudy the D * 1 (2600) and D * s1 (2700) resonances as the mixed states via the 2 3 S 1 -1 3 D 1 mixing by using the genuine wave functions calculated from our potential model.…”

A semi-relativistic potential model is adopted to calculate the mass spectra of charmed and charmed-strange meson states up to the 2D excitations. The strong decay properties are further analyzed with a chiral quark model by using the numerical wave functions obtained from the potential model. Based on our good descriptions of the mass and decay properties for the low-lying well-established states, we give a quark model classification for the high mass resonances observed in recent years. In the D-meson family, D 0 (2550) can be classified as the radially excited state D(2 1 S 0 ); D * 3 (2750) and D 2 (2740) can be classified as the second orbital excitations D(1 3 D 3 ) and D(1D ′ 2 ), respectively; D * J (3000) may be a candidate of D(1 3 F 4 ) or D(2 3 P 2 ); while D J (3000) may favor the high mass mixed state D(2P ′ 1 ); however, there still exist puzzles for understanding the natures of D * 1 (2600) and D * 1 (2760), whose decay properties cannot be well explained with either pure D(2 3 S 1 ) and D(1 3 D 1 ) states or their mixing. In the D s -meson family, D * s3 (2860) favors the D s (1 3 D 3 ) assignment; D * s1 (2700) and D * s1 (2860) may favor the mixed states |(S D) 1 L and |(S D) 1 H via the 2 3 S 1 -1 3 D 1 mixing, respectively; D sJ (3040) may favor D(2P 1 ) or D(2P ′1 ), or corresponds to a structure contributed by both D(2P 1 ) and D(2P ′ 1 ); however, the newly observed resonance D s0 (2590) + as an assignment of D s (2 1 S 0 ), neither the mass nor the width can be well understood in the present study. Many missing excited D-and D s -meson states have a relatively narrow width, they are most likely to be observed in their dominant decay channels in future experiments.
