Aerogel RICH Counter at the Belle II Detector

I. Adachi, N. Akopov, D. Augueste +36

We report on the design, operation, and performance of a novel proximity-focusing Ring Imaging Cherenkov (RICH) detector equipped with a multilayer focusing aerogel radiator, devel…

The LHCb upgrade I

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1305

The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger th…

Measurement of the photon-energy spectrum in inclusive decays identified using hadronic decays of the recoil meson in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +593

We measure the photon-energy spectrum in radiative bottom-meson () decays into inclusive final states involving a strange hadron and a photon. We use SuperKEKB electron-positron…
