The study on the structure of exotic states ${\chi }_{c1}(3872)$ via beauty-hadron decays in $pp$ collisions at $\sqrt{s}=8\mathrm{TeV}$

Chun-tai Wu, Zhi-Lei She, Xin-Ye Peng +4

A dynamically constrained phase-space coalescence (DCPC) model was introduced to study the exotic state ${\chi }_{c1}(3872)$ yield for three possible structures: tetraquark state, nucle…
