The Silicon Vertex Detector of the Belle II experimentPublic
The Belle II silicon vertex detector (SVD) is a four-layer double-sided silicon strip detector installed within the Belle II detector located at KEK, Japan. SVD has been operating smoothly and reliably since the start of data taking in March 2019. The data quality and radiation damage effects have been constantly monitored. In this article, we rep⦠|

Pixel Vertex Detector background generation using Generative Adversarial NetworksPublic
The Pixel Vertex Detector (PXD) is the innermost detector of the Belle II experiment. Information from the PXD, together with data from other detectors, allows to have a very precise vertex reconstruction. The effect of beam background on reconstruction is studied by adding measured or simulated background hit patterns to hits produced by simulate⦠|

Amplitude Analysis of B0 -> K+pi-pi0 DecaysPublic
The measurement of branching ratios and CP asymmetries of π΅ meson decays are essential tools for understanding the underlying physics. These measurements are particularly challenging for the decays of π΅ mesons to multi-body hadronic final states, since elaborate amplitude analyses are required to separate and measure the contributions of the interβ¦ |

Search for exotic states with $c\bar{c}s\bar{s}$ content at BellePublic
We present results for an analysis of $e^+e^β to D_s^+D_{sJ}^β A$ + c.c. processes in the continuum ($A$ = anything else) using the whole Belle dataset (980.1 fb$^{β1}$). The goal of the analysis is the study of $D_s^+ D_{s0}^*(2317)^β and D_s^+ D_{s1}(2460)^β$ invariant mass systems to search for possible exotic, resonant states with $c\bar{c}s\bβ¦ |

Measurement of the full set of kinematic moments of semileptonic π΅-meson decays with the Run 1 data set of Belle IIPublic
The determination of the Cabibbo-Kobayashi-Maskawa matrix element |πππ| relies on π β πβπβ transitions. The inclusive semileptonic process can be described with the Heavy Quark Expansion (HQE) and using the operator product expansion the total decay rate can be parameterized with a small number of non-perturbative parameters. These parameters cannβ¦ |

$B \rightarrow D^{**} \ell \nu $ Analysis at Belle IIPublic
There is currently some tension between the measured value of $R(D^{*})=\mathcal{B}(B \rightarrow D^{*} \tau \nu_{\tau})/ \mathcal{B}(B \rightarrow D^{*} \ell \nu_{\ell})$ and the Standard Model prediction, hinting at lepton universality violation. Semileptonic $B$ meson decays to $D^{**}$ mesons are background to the $R(D^{*})$ measurement, where⦠|

Slow pion identification at the Belle II PXD with machine learningPublic
The identification of slow pions in Belle II experiments presents a no- table challenge, arising from their high dE/dx energy loss and their short flight path in the tracking detectors. This study introduces a method employing advanced machine learning algorithms to accurately detect pions with momentum p<100 MeV/c exclusively with the Belle II p⦠|

Direct measurement of π
+-0 at Belle IIPublic
The ratio of the Ο(4π) β π΅+π΅β and Ο(4π) β π΅0 Β―π΅0 decay rates, π Β±0, represents a crucial input quantity to convert measured yields into branching fractions at π+πβ π΅-factory experiments. The most precise present day determinations rely on isospin assumptions. We present the status of a novel approach to determine the π΅Β± and π΅0 production fraction uβ¦ |
