Spectroscopic Exploration of Charmed-Strange Meson Using Regge Phenomenology
摘要
In recent years, the experimental discovery of charmed mesons has significantly increased. The latest report from the Particle Data Group (PDG) lists 10 observed excited charmed-strange mesons identified by various experimental collaborations. In this study, we conduct a systematic analysis of the \(D_s^{\pm }\) meson by utilizing Regge theory, a widely adopted framework for investigating hadron spectra. By assuming quasilinear Regge trajectories, we derive several relationships between the Regge slope, intercept, and meson masses. Using these relationships, we calculate the Regge slopes for the \(1^1S_0\) and \(1^3S_1\) trajectories in the \((J, M^2)\) plane to determine the masses of orbitally excited states. Furthermore, we evaluate the Regge parameters in the \((n, M^2)\) plane for each Regge line, allowing us to predict the masses of radially excited charmed-strange mesons on these trajectories. These predicted masses are then compared with both available experimental results and theoretical predictions from other models. Our predictions could provide valuable insights for future experimental studies and verification.
