49. Baryon-Baryon Scattering in $N_f = 2+1$ Lattice QCD

Dr 瀚洋 邢 (South China Normal University)

10/10/2026, 14:00

We present a preliminary lattice QCD study of baryon-baryon scattering using $N_f = 2+1$ CLQCD configurations. We focus primarily on the strangeness $S = -2$ $\Lambda\Lambda$ and $\Xi N$ systems to explore the properties of $H$-dibaryon near threshold using the Lüscher finite-volume quantization condition. Furthermore, we extend our study to baryon-baryon systems involving the $\Omega$ baryon....

20. DbarN meson-baryon scatter in Lattice QCD

Mr 啸 常 (中国科学院近代物理研究所)

This project studies the low-energy $\bar{D}N$ scattering in lattice QCD, focusing on the S-wave channels $I(J^P)=0\left(\frac12^-\right), 1\left(\frac12^-\right)$.

Finite-volume $\bar{D}N$ correlation functions are analyzed using the generalized eigenvalue problem (GEVP) to extract the two-body energy spectrum. The Lüscher formalism is then used to relate the finite-volume energy levels to...

27. $S$-wave scattering length of the $J/\psi J/\psi$ system from lattice QCD in coordinate space

Mr 嘉竣 谢 (School of Physical Sciences, University of Chinese Academy of Sciences, Beijing 100049, China)

10/10/2026, 14:55

The $J/\psi J/\psi$ energy spectra are extracted from lattice QCD by utilzing the Coordinate-Space Two-Hadron Operators, named as dumbbell method.

Finite-volume energies indicate an attractive interaction in total spin $S=0$ channel and a repulsive interaction in total spin $S=1$ channel and total spin $S=2$ channel.

The scattering lengths of three different total spin are also extracted...

19. calculate Λ → pℓ¯νℓ semileptonic decay in lattice QCD

Mr 鉴 郭 (中国科学院近代物理研究所)

10/10/2026, 15:10

This work presents a non-perturbative lattice-QCD study of the semileptonic decay (\Lambda \to p\ell\bar{\nu}_{\ell}), where (\ell=e,\mu). The main objective is to calculate the hadronic transition matrix element

$$ \langle p|\bar{u}\gamma^\mu(1-\gamma_5)s|\Lambda\rangle $$

and extract the corresponding vector and axial-vector form factors.

Two-point and three-point correlation...

22. η and η' mesons from lattice QCD

Mr 立强 李 (河北大学)

10/10/2026, 15:25

Understanding the masses of $\eta$ and $\eta$' mesons as well as the mixing between the original flavor singlet state and the neutral octet state is an important topic in low-energy strong-interaction physics. We determine masses and mixing angle of the $\eta$ and $\eta$' mesons in lattice QCD. The calculations are carried out on a set of 13 CLQCD gauge ensembles with $N_f$ = 2 + 1...

11. Portraits of Charmoniumlike States

Mr 清扬 刘 (ihep)

10/10/2026, 15:40

The charm quark density-density correlation is calculated for 1S and 1P conventional charmonia and $J^{PC}=1^{−+},0^{+−}$ charmoniumlike states from lattice QCD and are interpreted as spatial wave functions of these states with some approximations. The angular distributions of $c\bar{c}$ in conventional charmonia are found to be in accordance with the expectation of two-body systems, while...
