A Highschooler’s Guide to GeV-Range Electromagnetism / Chatterji, Satchit (Unlisted, IN) ; Desai, Aayush (Unlisted, IN) ; Dwarkesh, Aditya (Unlisted, IN) ; Ganesh, Anushree (Unlisted, IN) ; Kunder, Ameya (Unlisted, IN) ; Malhotra, Pulkit (Unlisted, IN) ; Sahoo, Roshni (Unlisted, IN) ; Shah, Jinal (Unlisted, IN) ; Velmurugan, Kiranbhaskar (Unlisted, IN) ; Joos, Markus (CERN) et al.
The following article has been written primarily by the high school students who make up the team “Cryptic Ontics”, one of the two winning teams in the 2018 edition of CERN’s Beamline for Schools (BL4S) competition, and is based on the set of experiments the students endeavoured to conduct over the course of a two-week period at CERN.

Gas Heating from Spinning and Non-Spinning Evaporating Primordial Black Holes / Laha, Ranjan ; Lu, Philip ; Takhistov, Volodymyr
Primordial black holes (PBHs) from the early Universe constitute a viable dark matter (DM) candidate and can span many orders of magnitude in mass. [...]

UPC: a powerful tool for ${\mathrm J}/\psi$ photoproduction analysis in ALICE / Ragoni, Simone
Ultra-peripheral collisions (UPC) occur when the interacting nuclei or protons have an impact parameter larger than the sum of their radii. [...]

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. [...]
