As the leading theory in particle physics, the Standard Model (SM) defines our understanding of the subatomic world. However, observed phenomena have proven that the SM, despite its great success, is not complete yet and the search for particles Beyond the Standard Model (BSM) has surged ever since. [...]

The pixel detector of the Belle II experiment is based on the DEPFET technology. Fora reliable readout, it is essential to determine the pedestal (baseline current) of each pixel.This work focuses on characterizing the pedestal measurements and their development overtime. [...]

In simulating high-energy particle collisions, Monte Carlo event generatorsemploy different models to create parton showers and replicate hadronization.The choice of model can influence the final state of the simulation and,consequently, the subsequent analysis of the generated event. This study utilizeda machine learning algorithm to discern the differences between quark and gluonjets generated through different approaches to showering and hadronization.Initially, particle jets from dijet events generated using Pythia, Sherpa and Herwigwere compared across various jet- and particle-level properties. [...]

The Standard Model of particle physics has been highly successful in describing fundamental particles and their interactions, but potential extensions are needed to address itslimitations. Precise measurements of rare decays, such as the radiative B → Xsγ decay, provide an opportunity to test Beyond Standard Model (BSM) theories, due to them being suppressed by the Standard Model [...]

act The production of a Wboson in association with a charm quark is a valuable process to study the relatively unconstrained strange quark parton distribution function of the proton. This work presents an analysis of gluon splitting as an important but not well understood background process to W+c production. [...]
