Description:
Author(s): Qiang Mao, Hua-Xing Chen, Wei Chen, Atsushi Hosaka, Xiang Liu, and Shi-Lin Zhu We study the P -wave bottom baryons using the method of QCD sum rule and heavy quark effective theory. Our results suggest that Λ b ( 5912 ) 0 and Λ b ( 5920 ) 0 can be well described by the baryon doublet [ 3 ¯ F , 1 , 1 , ρ ] , and they belong to the S U ( 3 ) 3 ¯ F multiplets of J P = 1 / 2 − and 3 / 2 − . Their S U ( 3 ) flavor partners… [Phys. Rev. D 92, 114007] Published Tue Dec 01, 2015
