Revisiting $O (N)$ $σ$ model at unphysical pion masses and high temperatures. II. The vacuum structure and thermal $σ$ pole trajectory with cross-channel improvements

Yuan-Lin Lyu, Qu-Zhi Li, Zhiguang Xiao +1

The effective potential of the $O (N)$ model at large $N$ limit is reinvestigated with varying pion mass and temperature. For large pion masses and high temperatures, we find the ph…

Revisiting $O (N)$ $σ$ model at unphysical pion masses and high temperatures

Yuan-Lin Lyu, Qu-Zhi Li, Zhiguang Xiao +1

Roy-equation analyses on lattice data of $π π$ scattering phase shifts at $m_{π} = 391$ MeV reveals that the lowest $f_{0}$ meson becomes a bound state under this condition. In addition, t…

The $X (6900)$ peak could be a molecular state

Ye Lu, Chang Chen, Kai-Ge Kang +2

The analyses of the LHCb data on $X (6900)$ found in di- $J / ψ$ and $J / ψ ψ (3686)$ systems are performed using a momentum-dependent {Flatté}-like parameterization. The use of the pole c…
