Charm studies at Belle experiment

TL;DR

This paper summarizes recent experimental results on charm physics from the Belle experiment, including measurements of mixing, CP violation, rare decays, and charmed baryons, advancing understanding of charm quark behavior.

Contribution

It provides updated measurements and new limits in charm mixing, CP violation, rare decays, and charmed baryon studies at Belle, with improved precision and new findings.

Findings

More precise measurements of $D^0-ar{D}^0$ mixing and CP violation.

Most restrictive upper limits on $D^0$ rare decays.

New results on doubly charmed and strange baryons.

Abstract

In this proceeding, we give a summary of the new published or preliminary experimental results on charm studies at Belle experiment at KEKB. It mainly includes three parts: (1) $D^0-\bar{D}^0$ mixing and CP violation. Some decay channels give the new measurement results with more precise; (2) search for $D^0$ rare decay with most restrictive upper limit; (3) some new results for charmed baryon studies, such as doubly charmed baryons, charmed strange baryon and so on.
