Probing Neutral Triple Gauge Couplings at e- p colliders

Xue-Jia Cheng, Chong-Xing Yue, Ji-Chong Yang +1

The Standard Model Effective Field Theory~(SMEFT) has attracted much attention as a model-independent way for probing new physical signals. In the SMEFT framework, collide…

Nodal mechanism for the suppressed decay of in the Bethe--Salpeter framework

Bing-Dong Wan, Sheng-Qi Zhang

The strong decay is anomalously suppressed despite ample phase space, whereas the and channels remain sizable. In this work, we study…

Spectroscopy of hidden-heavy tetraquark states with in a color-octet configuration

Bing-Dong Wan, Jun-Hao Zhang, Yan Zhang +1

Within the QCD sum-rule framework, we investigate hidden-heavy tetraquark channels with the exotic quantum number using four representative local color-octet--octet…

QCD sum rule analysis of local meson-meson currents for the state

Yi-Qi Mu, Peng-Wen Xu, Si-Tong Chen +3

The nature of the recently observed state, reported by the COMPASS Collaboration as a candidate strange crypto-exotic meson with , remains unclear. In this work,…

Leptogenesis in the littlest inverse seesaw model

Yan Shao, Zhen-hua Zhao, Yi-Fei Duan

The littlest inverse seesaw (LIS) model represents the first low-scale seesaw framework to successfully account for all six physical observables of the neutrino sector with merely…

The S-wave topped meson

Jun-Hao Zhang, Shuo Yang, Bing-Dong Wan

Motivated by the recent near-threshold enhancement in top-quark pair production reported by CMS and ATLAS, we study the S-wave spectral structure of heavy-light systems containing…
