29. Direct calculation of trace anomaly on CLQCD ensembles

晨宇 章 (ITP)

12/10/2025, 14:30

In this work we present the direct calculation of trace anomaly matrix elements $\hat{\beta}\langle \mathrm{Tr}[g^2F^2]\rangle_H$ in kinds of baryons on the CLQCD ensembles, and compare with those from the sum rule. We also make a joint fit of 30 hadrons to extract the anomalous dimensions $\hat{\beta}$ and $\gamma_m$ in the Wilson flow scheme at different energy scales.

26. Bottom baryon mass and trace anomaly contribution

Using anisotropic clover action for valence bottom quark on CLQCD ensembles with several different lattice spacing and various pion masses, we present the accurately prediction of ground state spin-1/2 and spin-3/2 baryon masses containing bottom quark, and extract sigma term contribution to bottom hadron masses using Feynman-Hellman method.

3. Contraining DVCS Compton Form Factors Using Lattice QCD calculations

The lattice QCD calculation of gravitational form factors (GFFs) are employed to determine the subtraction constant through dispersion relations of Deeply Virtual Compton Scattering (DVCS), thus constraining significantly the real part of the Compton Form Factors (CFFs) in a global analysis of proton data.This is realised by a synthesis of the dispersion relation and the neural networks, of...

6. Study of the $D_s \to \phi \ell \nu_\ell$ semileptonic decay with (2+1)-flavor lattice QCD

高峰 樊 (IHEP)

Semi-leptonic decays offer an ideal place to deeply understand hadronic transitions in the nonperturbative region of QCD and explore the weak and strong interactions in the charm sector. Combining with experimental data, the CKM matrix element can be extracted, and it helps to test unitarity of CKM matrix and searching for new physics beyond SM. In this talk, the full lattice QCD calculations...

31. Radiative decay and electromagnetic radius of heavy-light mesons

文正 侯 (south china normal university)

On the five ensembles generated by the CLQCD collaboration, we computed decay width of D_s^→D_s γ，D_ ^(+)→D_ ^+ γ and D_ ^(0)→D_ ^0 γ. Chiral extrapolation and lattice spacing extrapolation were performed, yielding significantly improved precission. The precision for D_ ^(+)→D_ ^+ γ was improved ten times compared to previous studies, while the precision for D_ ^(*0)→D_ ^0 γ was improved...
