Feasibility study of exotic particle X(3872) with ATHENA in EIC experiment and its possible structures

Abstract

The normal hadrons known as protons, neutrons, pions, etc are classified according to the quark model but there are some other particles named exotic particles that can not be classified by the quark model but are favored by Quantum Chromo dynamics (QCD). Some of these particles contain heavy quarks and have di↵erent quark compositions than normal hadrons like four quarks, five quarks, gluonic de grees of freedom, and gluon-gluon interactions. A feasibility study of exotic particles has been done in the future Electron-Ion Collider (EIC) experiment with a totally hermetic electron nucleus apparatus (ATHENA) detector concept. A phenomeno logical approach for understanding exotic particles in quark-gluon plasma (QGP) medium with a multiphase transport model (AMPT) has been done.
