Study The Properties Of Mesons By³P₀Model Based On Relativistic Wave Function

Gaussian Expansion Method (GEM) is a solve method of few-body systems, andit has turn out to be an effective method for bound states, and it is used in many fieldsnow. In this article, the method was used to solve the relativistic consitiuent quarkmodel to got the space wave function, which was used to replace simple harmonicoscillator (SHO) wave functions in3P0model to study the properties of mesons.DJ3000and D J3000is observed where mass near3000MeV recently. Thiswork investigated the open charmed meson states whose theory mass is near3000MeV, it can be found that DJ3000is likely to be11F3or11S0state, andD J3000is one of13F2,13F4,23P2and33S1if these mesons are considered tobe single state. It can not be ruled out the possibility to be1F state for DJ3000ifit is considered to be mix state. To make sure which states these mesons are, it needsmore experiment data.
