Abstract

We have investigated the spectroscopy of the different exotic tetraquarks such as K, \(f_{0}\), D, Y, \(Z_{s}\), \(Z_{c}\), \(T_{cc}\), \(T_{cc}\), \(X_{c}\) etc. embedded in a strongly interacting medium with the variation of density and temperature of the medium. The momentum and density dependent potential and power law type of temperature scaling play crucial roles in this regard. The tetraquarks have been treated as composite system of diquark-antidiquark in the context of Composite Fermion (CF) quasiparticle model and their effective masses have been estimated. Moreover, when these tetraquarks are embedded in a strongly interacting medium, the density and the temperature of the medium affect their masses. These variations of masses have been explored in detail and have been displayed in the graphs. They have also been compared with works of others.

具有动量依赖势的介质中温度和密度对四夸克质量的影响

我们研究了嵌入强相互作用介质中的K、\(f_{0}\)、D、Y、\(Z_{s}\)、\(Z_{c}\)、\(T_{cc}\)、\(T_{cc}\)、\(X_{c}\)等不同的奇异四夸克的光谱随介质密度和温度的变化。动量和密度相关的势和幂律类型的温度标度在这方面起着至关重要的作用。在复合费米子（CF）准粒子模型的背景下，将四夸克视为重夸克-反重夸克的复合体系，并对其有效质量进行了估计。此外，当这些四夸克嵌入强相互作用的介质中时，介质的密度和温度会影响它们的质量。质量的这些变化已经被详细地研究过，并在图表中显示出来。他们还与其他人的作品进行了比较。

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
