Effective Theory Calculation in Beauty-charm Meson Decays

03/20 2023 Seminar
  • Title Effective Theory Calculation in Beauty-charm Meson Decays
  • Speaker Ruilin Zhu (Nanjing Normal University)
  • Date 9:00 Mar. 20, 2023
  • Venue Room 322, ITP North Building
  • Abstract
    Heavy flavor physics is closely related and cross-integrated to all directions in high-energy physics. High-precision calculation and effective theory development is important to precisely test the standard model and hunt for new physics. In this talk, I will introduce the latest status for the study of beauty-charm meson family, and then report the two-loop calculation for the decay constant of vector beauty-charm meson. Concerning the nonconvergence of the recent three-loop correction to the decay constants, we try to give a reasonable solution which simultaneously explain the hyperfine splitting and convergent decay constant.
