J=3/2粲超夸克

J=3/2 charmed hypertriton

H. Garcilazo, A. Valcarce, T. F. Carames

摘要:

通过求解精确的三体方程,研究了具有粲$+1$的三重子系统。我们利用从手征组分夸克模型得到的重子-重子相互作用寻找可能的束缚态。$Λ_c \leftrightarrow Σ_c$转换的较小影响颠倒了$(I,J)=(0,1/2)$和$(I,J)=(0,3/2)$状态的顺序,在奇怪扇区上相当接近。由于大的约化质量而导致的动能的减小在$(I,J)=(0,3/2)$通道中产生束缚态。在修正库仑效应后,结合能将在140和715 keV之间。

英文摘要:

By solving exact three-body equations, we study the three-baryon system with charm $+1$. We look for possible bound states using baryon-baryon interactions obtained from a chiral constituent quark model. The smaller effect of the $Λ_c \leftrightarrow Σ_c$ conversion reverses the order of the $(I,J)=(0,1/2)$ and $(I,J)=(0,3/2)$ states, rather close on the strange sector. The diminishing of the kinetic energy due to the large reduced mass gives rise to a bound state in the $(I,J)=(0,3/2)$ channel. After correcting for Coulomb effects the binding energy would be between 140 and 715 keV.
