Heavy-light meson spectroscopy and Regge trajectories in the relativistic quark model

Abstract

Masses of the ground, orbitally and radially excited states of heavy-light mesons are calculated within the framework of the QCD-motivated relativistic quark model based on the quasipotential approach. Both light (q = u, d, s) and heavy (Q = c, b) quarks are treated fully relativistically without application of the heavy quark 1/m Q expansion. The Regge trajectories in the (M 2 ,J) and (M 2 , n r ) planes are investigated and their parameters are obtained. The results are in good agreement with available experimental data except for the masses of the anomalous D * s0 (2317), D s1 (2460) and D * sJ (2860) states.

Higher radial and orbital excitations in the charmed meson family

“…We also notice a study of the heavy-light meson spectroscopy within the framework of the QCD-motivated relativistic quark model based on the quasipotential approach [79]. The conclusion of mass spectrum obtained above in the present work is consistent with those of Ref.…”

Study of orbitally excitedBmesons and evidence for a newBπresonance

“…[38] the only predicted states with mass values between the B ÃÃ0;þ masses and 6100 MeV=c 2 are the two radial excitations 2ð 1 S 0 Þ and 2ð 3 S 1 Þ, with masses of 5890 and 5906 MeV=c 2 , respectively. The next orbital B excitation, expected to decay by D-wave having L ¼ 2, is at a mass near 6100 MeV=c 2 .…”

“…If the 2S and 1D J P ¼ 1 − states are close in mass, they may mix. In the literature, the D Ã s1 ð2700Þ − is usually interpreted as being the 1 − 2S state, while the D Ã sJ ð2860Þ − is a candidate to be the 3 − 1D state [7][8][9][10][11][12][13][14][15]. However, several papers (e.g., Ref.…”
