Analysis of the Triply Heavy Baryon States with QCD Sum Rules
Analysis of the Triply Heavy Baryon States with QCD Sum Rules
摘要
In this article, we study the (1/2) ± and (3/2)± triply heavy baryon states in a systematic way by subtracting the contributions from the corresponding (1/2)■ and (3/2)■ triply heavy baryon states with the QCD sum rules, and make reasonable predictions for their masses.
