Lattice QCD study of the $K^{*} (892)$ resonance at the physical point

Qu-Zhi Li, Chuan Liu, Liuming Liu +4

We present a lattice QCD study of the $K^{*} (892)$ resonance using eight $N_{f} = 2 + 1$ Wilson-Clover ensembles with three lattice spacings and six pion masses ranging from 135 to 320 MeV…

Studies on quark-mass dependence of the $N^{*} (920)$ pole from $I ¨ N$ $I ¨ $ PT amplitudes

Xu Wang, Kai-Ge Kang, Qu-Zhi Li +2

The quark-mass dependence of the $N^{*} (920)$ pole is analyzed using $K$ -matrix method, with the $I ¨ N$ scattering amplitude calculated up to $O (p^{3})$ order in chiral perturbation the…

Review on recent progress in the study of the $N^{*} (920)$ subthreshold singularity and the $I ¨ / f_{0} (500)$ meson

Qu-Zhi Li, Zhiguang Xiao, Han-Qing Zheng

We summarize recent results on studies of $I ¨ I ¨ $ and $I ¨ N$ scatterings. They include the finding of a negative-parity nucleon pole with a mass lower than the nucleon mass, and the…

Quantum Weak Measurement Amplifies Dispersion Signal of Rydberg Atomic System

Yinghang Jiang, Jiguo Wu, Meng Shi +4

Rydberg atoms, with their long coherence time and large electric dipole moment, are pivotal in quantum precision measurement. In the process of approaching the standard quantum lim…

Revisiting $O (N)$ $I ¨ $ model at unphysical pion masses and high temperatures. II. The vacuum structure and thermal $I ¨ $ 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…
