Particle identification with the Belle II calorimeter using machine learningPublic
I present an application of a convolutional neural network (CNN) to separate muons and pions in the Belle II electromagnetic calorimeter (ECL). The ECL is designed to measure the energy deposited by charged and neutral particles. It also provides important contributions to the particle identification (PID) system. Identification of low-momenta muoโฆ |

The Belle II Upgrade ProgramPublic
The Belle II experiment at the SuperKEKB e+e- collider has started data taking in 2019 with the perspective of collecting 50ab-1 in the course of the next several years. The detector is working well with very good performance, but the first years of running are showing novel challenges and opportunities for reliable and efficient detector operatioโฆ |

Tau physics at Belle IIPublic
The low-background environment of electron-positron collisions along with the large expected sample size and an hermetic detector make Belle II the premier experiment for studying tau-lepton physics. A competitive measurement of the mass of the tau lepton is reported based on a a small data set, and studies for world-leading measurements of tau liโฆ |

Studies of the X(3872) at Belle IIPublic
The X(3872) is one of the most puzzling resonances ever observed. First seen by the Belle Collaboration in 2003, it solicited the effort of a hundred of experimental physicists and dozens of theorists, who nowadays are trying yet to shed light on the nature of this peculiar resonant state. It was seen in several decay modes and different productioโฆ |

Operation and performance of the Belle II Aerogel RICH detectorPublic
The Belle II experiment at the SuperKEKB asymmetric-energy $e^{+}e^{-}$ collider is a B factory experiment to search for new phenomena beyond the Standard Model. One of the most important point in the experiment is a particle identification, especially the separation between kaons and pions. Thus, a proximity focusing Aerogel Ring Imaging Cherenโฆ |

Flavor physics with electroweak-penquins and semileptonic decays at Belle IIPublic
In the recent years, several measurements of B-decays with flavor changing neutral currents, i.e. ๐โ๐ transitions hint at deviations from the Standard Model (SM) predictions. In addition there are discrepancies with the SM predictions in ๐โ๐๐๐ decays. The Belle II experiment is a substantial upgrade of the Belle detector and operates at the SuperKโฆ |
