Analysis of the doubly heavy baryon states and pentaquark states with QCD sum rules
Abstract In this article, we study the doubly heavy baryon states and pentaquark states with the QCD sum rules by carrying out the operator product expansion up to the vacuum condensates of dimension 7 and 13 respectively in a consistent way. In calculations, we separate the contributions of the neg...
