Measurement of the $ \tau $ lepton polarization in Z boson decays in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
The polarization of $ \tau $ leptons is measured using leptonic and hadronic $ \tau $ lepton decays in Z $\to\tau^{+}\tau^{-} $ events in proton-proton collisions at $ \sqrt{s}= $ 13 TeV recorded by CMS at the CERN LHC with an integrated luminosity of 36.3 fb$ ^{-1} $. [...]

Cherenkov image correction method for cloud-affected observations /RE23/CTA-LST Collaboration
The presence of clouds during observations with Imaging Atmospheric Cherenkov Telescopes can strongly affect the performance of the instrument due to additional light absorption. If not corrected for, it can lead to increased systematic errors in the measurements. [...]
