29. Lattice calculation of the $K_L$ and $K_S$ mass difference for physical quark masses

Dr Bigeng Wang (U)

The two neutral kaon states in nature, the $K_L$ (long-lived) and $K_S$ (short-lived) mesons, are the two time-evolution eigenstates of the $K^0 - \overline{K^0}$ mixing system. The prediction of their mass difference $\Delta m_K$ based on the standard model is an important goal of lattice QCD. In this talk, I will present the preliminary results from a calculation performed on an ensemble of...

31. Charmonia Decays on the Lattice

Dr 雨 孟 (school of physics Peking Uniersity)

02/11/2021, 10:30

The charmonia decays present an ideal laboratory for testing the interplay between perturbative and nonperturbative QCD. In this talk, I focus on the all-photon decay and radiative decay of charmoina. Adopting a new method proposed recently, we perform the systematic lattice calculations on ηc/χc0→2γ and J/ψ→γηc. By using three Nf=2 twisted mass gauge ensembles with different lattice spacings,...

56. Lattice QCD calculation of the two-photon exchange contribution to the muonic-hydrogen Lamb shift

杨 傅 (PKU)

02/11/2021, 11:50

The measurement of muonic-hydrogen spectroscopy provides the most precise determination of the proton charge radius, where the two-photon exchange contribution plays an important role in the understanding of μH spectroscopy. We will report a lattice QCD calculation of the two-photon exchange contribution by constructing the proton four-point correlation function.
