Left-hand cut problem in lattice QCD and an EFT-based solution
Lu Meng, Vadim Baru, Evgeny Epelbaum +2
Lattice QCD has become an essential tool for studying the hadron-hadron interaction from the first principles. However, when extracting infinite-volume scattering parameters from f…
Existence of the and three-body molecular states
Yan-Ke Chen, Lu Meng, Jun-Zhang Wang +1
We investigate the existence of the three-body molecular state composed of within the one-boson-exchange (OBE) model. A major challenge is that while the pseudoscal…
Electromagnetic polarizabilities of the spin- singly heavy baryons in heavy baryon chiral perturbation theory
Yan-Ke Chen, Liang-Zhen Wen, Lu Meng +1
We calculate the electromagnetic polarizabilities of the spin- singly heavy baryons in the heavy baryon chiral perturbation theory up to . We estimat…
Spectrum of the fully-heavy tetraquark state
Guang-Juan Wang, Lu Meng, Shi-Lin Zhu
In this work, we systematically calculate the mass spectra of the -wave fully heavy tetraquark states , , and in two nonrelativi…
Trilepton and tetralepton bound and resonant states: the QED counterpart of multiquark states
Yao Ma, Lu Meng, Liang-Zhen Wen +1
This work presents the first prediction of tetralepton resonant states containing muons, extending beyond the simplest tetralepton system, dipositronium (). With the…
The double thresholds distort the lineshapes of the resonance
Lu Meng, Bo Wang, Shi-Lin Zhu
Very recently, the LHCb Collaboration reported the first observation of the hidden charm pentaquark with strangeness, . Considering this state is very close to…
