/ Vismaya V S ; S. Sandilya ; K. Trabelsi
[BELLE2-CONF-PROC-2023-028]
12 July 2023
Recent measurements of semileptonic decays show a difference between the branching ratio of the sum of exclusive decay rates and the inclusive $b \rightarrow c \ell \nu$ decay rate (the so-called Semi-Leptonic (SL) gap) which affects the interpretation of the CKM element $|Vcb|$. [...]

| 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. [...]
