P-wave $c\bar{c}$ meson contributions in exotic hadrons

Since $X(3872)$ was reported by the Belle collaboration in 2003, exotic hadrons containing charm quarks have been reported almost every year. Many of these are hidden charm exotic hadrons. In this study, we analyze the exotic hadrons $X(3860)$, $X(3872)$, and $Z(3930)$ with the same quantum number as the P-wave $c\bar{c}$ meson $\chi_{cJ}(2P)$ as superposition states of hadronic molecular states and bare $c\bar{c}$ states.
