摘要
Motivated by great progresses in experiments in searching for the heavy baryons, we systematically analyze the mass spectra and root mean square radius of single heavy baryons AQ, EQ and QQ. The calculations of the mass spectra are carried out in the frame work of relativized quark model, where the baryon is regarded as a three-body system of quarks. Our results show that the mass of single heavy baryon with & lambda;-mode is lower than those of the p-mode and & lambda;-p mixing mode, which indicates that the lowest state is dominated by the & lambda;-mode. Basing on this research, we systematically calculate the mass spectra and the root mean square radius of the baryons with & lambda; excited mode. With these predicated mass spectra, the Regge trajectories in the (J, M2) plane are constructed, and the slopes, intercepts of the Regge trajectories are obtained by linear fitting. It is found that all available experimental data are well reproduced by model predictions and fit nicely to the constructed Regge trajectories.& COPY; 2023 The Author(s). Published by Elsevier B.V.
