Abstract

We present one example of the complete next-to-leading order potential of a ${{B}^{{( * )}}}$ – ${{\bar {B}}^{{( * )}}}$ system for the partial waves ${{J}^{{PC}}}$ = 0⁺⁺, 1⁺⁺, 1^+–, 2⁺⁺. The potential is ready to be used in a Lippmann-Schwinger equation. Then a fit to data for the exotic states Z_b(10610) and Z_b(10650) should reveal important information about the convergence of the chiral expansion for the given system.

摘要

我们提供一个\（{{B} ^ {{（*}}}}} \） – \（{{\ bar {B}} ^ {{（*） }}} \）分波\（{{J} ^ {{PC}}} \）系统= 0 ⁺⁺，1 ⁺⁺，1 ^{+ –}，2 ⁺⁺。该电位已准备好在Lippmann-Schwinger方程中使用。然后，对于外来状态Z _b（10610）和Z _b（10650）的数据的拟合将揭示有关给定系统手性展开的收敛性的重要信息。
