摘要

目前，已经通过实验发现了具有隐藏魅力和美丽的奇异强子，它们被解释为四夸克和五夸克。在强子的夸克-二夸克模型中，这些共振的动力学被简化为四夸克中的一个夸克和反夸克以及五夸克中的一对夸克和一个反夸克的相互作用。在该模型中，我们得到并讨论了具有隐藏粲子的重四夸克和五夸克在产生一对开放强子的情况下，夸克衰变模式宽度与衰变的比值。

Ratios Between Decay Widths of Exotic Doubly Heavy Hadrons in the Diquark Model

At present, exotic hadrons with hidden charm and beauty, interpreted as tetra- and pentaquarks, have been experimentally discovered. Within the quark-diquark model of hadrons, the dynamics of these resonances is reduced to the interaction of a diquark and antidiquark in tetraquarks and a pair of diquarks and an antiquark in pentaquarks. Within this model, the ratios of the widths of quarkonium decay modes to decays with the production of a pair of hadrons with an open flavor for doubly heavy tetra- and pentaquarks with hidden charm have been obtained and discussed.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
