Contribution to the 2023 Electroweak session of the 57th Rencontres de Moriond
17 July 2023
We report two new measurements for tests of lepton flavor universality between electrons and muons using semileptonic $B$ decays with a data set of $189~\mathrm{fb}^{-1}$ collected at the Belle II experiment between 2019 and 2021. [...]

| Search for the decay $B \rightarrow D^* \eta \pi$ in Belle II
/ 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 $|Vcb|$. [...]

| Charged Particle Identification Performances in Belle II
/ Swarna Prabha Maharana; ; Vismaya V S; ; Saurabh Sandilya
[BELLE2-CONF-PROC-2023-027]
12 July 2023
An efficient Particle identification(PID) is crucial for Belle II as it deals with a much higher event rate than Belle and ultimately with a more extensive background. [...]

| 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. [...]
