Then the phenomenological model - vector-scalar (UV) form is discussed, which is used to describe different decay modes of B meson. On this basis, the results of comparing B meson two-body non-light decay with the theoretical predictions of the standard model are analyzed, and the possible new physics effects are explained.Next, the numerical tools and calculation methods used in this paper are introduced, including large-scale Monte Carlo (simulation-based) method, MCMC Bayesian statistical method, and some commonly used physics software.精品文档---下载后可任意编辑Finally, the research plan of this paper is discussed, including further perfecting and improving the phenomenological model, developing more efficient numerical tools, strengthening the sample size of experimental data, and adding more data samples.Keywords: B meson, two-body non-light decay, phenomenological model, new physics effects, numerical tools.
