Optimizing large-scale structure data analysis with the theoretical error likelihood / Chudaykin, Anton ; Ivanov, Mikhail M. ; Simonović, Marko
An important aspect of large-scale structure data analysis is the presence of non-negligible theoretical uncertainties, which become increasingly important on small scales. [...]

Jet measurements with ALICE: substructure, dead cone, charm jets / Vertesi, Robert
A selection of recent jet measurements are presented from the ALICE experiment at the CERN LHC in proton-proton collisions at $\sqrt{s}=13$ TeV, focusing on substructure results for inclusive and charmed jets. [...]

Rare decays at the CERN high-intensity kaon beam facility
Precision measurements of the branching ratios (BRs) for rare kaon decays can provide unique constraints on CKM unitarity and may reveal the existence of new physics. [...]

Quarkonia production as a function of charged-particle multiplicity in pp collisions at $\sqrt{s}=13$ TeV with ALICE / Ding, Yanchun
In pp collisions at LHC energies, heavy quarks are produced in initial hard scatterings and then these quarks hadronize in either open heavy-flavor hadrons or quarkonia (e.g. [...]

Systematic error studies for the charged particle EDM measurement proposal / Tahar, M. Haj (CERN) ; Carli, C. (CERN)
Proposals aimed at measuring the Electric Dipole Moment (EDM) for charged particles require a good understanding of the systematic errors that can contribute to a vertical spin buildup mimicking the EDM signal to be detected. [...]

Interstrip Capacitances of the Readout Board used in Large Triple-GEM Detectors for the CMS Muon Upgrade / CMS Muon Group Collaboration
We present analytical calculations, Finite Element Analysis modeling, and physical measurements of the interstrip capacitances for different potential strip geometries and dimensions of the readout boards for the GE2/1 triple-Gas Electron Multiplier detector in the CMS muon system upgrade. [...]
