| 英文摘要 | We study the excited B mesons' contributions to the coupled-channel effects under the framework of the P-3(0) model for the bottomonium. Contrary to what has been widely accepted, the contributions of P wave B mesons are generally the largest, and to some extent, this result is independent of the potential parameters. We also push the calculation beyond (1P) and carefully analyze the contributions of (2S). A form factor is a key ingredient to suppress the contributions of (2S) for low lying bottomonia. However, this suppression mechanism is not efficient for highly excited bottomonia, such as Upsilon(5S) and Upsilon(6S). We give explanations why this difficulty happens to the P-3(0) model and suggest analyzing the flux-tube breaking model for the full calculation of coupled-channel effects. |
