论文摘要
使用非层压的潜在模型，研究了单一迷人和底部重子的质谱，$λ_{C/B}（1/2^\ pm，3/2^ - ）$和$ξ_{C/B}（1/2^\ pm，3/2^ - ）$，使用具有重型的潜在模型，并具有较重的潜在模型。标量和伪级diquark的质量取自手性有效理论。 $ u_a（1）$异常的效果引起了奇怪和非胜利伪级diquarks之间的反向层次结构，这导致了单一重型重底重子元的$ρ$ mmode刺激。
The mass spectra of singly charmed and bottom baryons, $Λ_{c/b}(1/2^\pm,3/2^-)$ and $Ξ_{c/b}(1/2^\pm,3/2^-)$, are investigated using a nonrelativistic potential model with a heavy quark and a light diquark. The masses of the scalar and pseudoscalar diquarks are taken from a chiral effective theory. The effect of $U_A(1)$ anomaly induces an inverse hierarchy between the masses of strange and non-strange pseudoscalar diquarks, which leads to a similar inverse mass ordering in $ρ$-mode excitations of singly heavy baryons.
