Overview of flavor physics results at Belle

We will present recent topics of the flavor physics in decays of the heavy mesons at the Belle experiment. Most of the results are based on a full data set which corresponds to 772 million BB̄ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e− collider. We also discuss about prospects of the studies in the future B-factory experiment

Three-Dimensional Elastic Analysis of a Structure with Holes Using Accelerated Coupling-Matrix-Free Iterative s-Version FEM

Some improvements of the coupling-matrix-free iterative s-version finite element method (FEM) to shorten its computational time are proposed. Then, the proposed method is applied to three-dimensional stress concentration problems. For sufficiently small computational time for practical use, two key techniques are introduced. First, the iteration is accelerated drastically by using the proposed convergence acceleration techniques. Secondly, stress transfers between global and local meshes are accelerated considerably by a bucket search algorithm. The proposed method was more than one hundred times faster than the straightforward algorithm of the coupling-matrix-free iterative s-version FEM

Summary of Working Group 4: Mixing and mixing-related CP violation in the B system: Δm, , Φs, Φ1/β, Φ2/α, Φ3/γ

This is a summary of the latest results in meson mixing and mixing-related CP violation presented at CKM 2021. We place these in the context of both recent experimental measurements, theoretical developments and future prospects in the field
