In recent years, study of pentaquarks as the exotic states of multiquark particles have been in progress experimentally and theoretically. A motivation for studying these new particles has been to better understanding of the strong interactions and the QCD theory. In this work, our aim is to calculate the mass spectrum of possible heavy pentaquarks for which we consider a two-body system containing an antiquark and two-diquarks. Using the Cornell potential and the spin–spin interaction we, first, calculate the diquarks masses and in the following the masses and the spin-dependent energies of heavy pentaquarks in their ground states. We will compare our theoretical result for $$\hbox {P}_{\mathrm{c}} =\left\{ {\bar{{\mathrm{c}}}\left[ {\mathrm{cu}} \right] _{\mathrm{s}=1} \left[ {\mathrm{ud}} \right] _{\mathrm{s}=0},\,\,\hbox {J}^{\mathrm{p}}=3/2^{-}} \right\} $$ with the value reported by the LHCb collaboration.

在狄夸克模型中确定重五夸克的质量和能谱

近年来，对作为多夸克粒子奇异状态的五夸克的研究在实验和理论上都在取得进展。研究这些新粒子的动机是为了更好地理解强相互作用和 QCD 理论。在这项工作中，我们的目标是计算可能的重五夸克的质谱，我们考虑包含一个反夸克和两个双夸克的双体系统。使用康奈尔势和自旋-自旋相互作用，我们首先计算双夸克质量，然后计算重五夸克基态的质量和自旋相关能量。我们将比较 $$\hbox {P}_{\mathrm{c}} =\left\{ {\bar{{\mathrm{c}}}\left[ {\mathrm{cu}} \右] _{\mathrm{s}=1} \left[ {\mathrm{ud}} \right] _{\mathrm{s}=0},\,\,
