| Search for Wrong-Sign D0 → K+π−π0 decay at Belle II
/ Chanchal Sharma
[BELLE2-CONF-PROC-2023-024]
12 July 2023
In the standard model, mixing and CP violation in the charm sector are expected to be very small, and thus, they constitute a sensitive probe for potential new physics contributions. [...]
