Calibration of aerogel ring-imaging Cherenkov detector in Belle II
Manca Mrvar, Rok Pestotnik
Doktorska disertacija
Oznake: The Belle II spectrometer;calibration;Cherenkov photons;the charged kaon/pion separation;hybrid avalanche photodetector;particle identification;Ring-Imaging Cherenkov detector.;
The Aerogel Ring-Imaging Cherenkov detector (ARICH) provides a charged particle identification in the endcap region of the Belle II spectrometer at the SuperKEKB asymmetric-energy $e^+ e^−$ collider in Tsukuba, Japan. The ARICH consists of a double layer aerogel radiator in a focusing configuration, ...

We report a determination of the CKM angle ϕ3, also known as γ, from a combination of measurements using samples of up to 711 fb−1 from the Belle experiment and up to 362 fb−1 from the Belle II experiment. We combine results from analyses of B+ → DK+, B+ → Dπ+, and B+ → D*K+ decays, where D is an ad ...

We present the result of a search for the charged-lepton-flavor violating decay τ− → μ−μ+μ− using a 424 fb−1 sample of data recorded by the Belle II experiment at the SuperKEKB e+e− collider. The selection of e+e− → τ+τ− events is based on an inclusive reconstruction of the non-signal tau decay, and ...

We search for a new gauge boson Z′ that couples only to heavy leptons and their corresponding neutrinos in the process e+e−→Z′(→μ+μ−)μ+μ−, using a 643  fb−1 data sample collected by the Belle experiment at or near the Υ(1S,2S,3S,4S,5S) resonances at the KEKB collider. While previous searches for Z′ ...

We present a study of the rare charm meson decays $D^0 \to K^+K^-e^+e^-, \pi^+\pi^-e^+e^-$, and $K^-\pi^+e^+e^-$ using a 942 fb$^{-1}$ dataset collected by the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We identify $D^0$ candidates via the charge of the pion from $D^{\ast +} \to ...
