Measurement of $Z\gamma\gamma$ production in $pp$ collisions at $\sqrt{s}= 13$ TeV with the ATLAS detector
Cross-sections for the production of a $Z$ boson in association with two photons are measured in proton-proton collisions at a centre-of-mass energy of 13 TeV. [...]

Isospin-breaking corrections to light-meson leptonic decays from lattice simulations at physical quark masses / Boyle, Peter (Los Alamos Natl. Lab., Theor. Div. ; Los Alamos ; Edinburgh U.) ; Di Carlo, Matteo ; Erben, Felix ; Gülpers, Vera (Edinburgh U.) ; Hansen, Maxwell T. ; Harris, Tim ; Hermansson-Truedsson, Nils ; Hodgson, Raoul ; Jüttner, Andreas (Southampton U. ; CERN) ; hÓgáin, Fionn Ó. et al.
The decreasing uncertainties in theoretical predictions and experimental measurements of several hadronic observables related to weak processes, which in many cases are now smaller than $\mathrm{O}(1\%)$, require theoretical calculations to include subleading corrections that were neglected so far. [...]

The Rumble in the Meson: a leptoquark versus a $Z^\prime$ to fit $b \rightarrow s \mu^+ \mu^-$ anomalies / Allanach, Ben (Cambridge U., DAMTP ; CERN) ; Davighi, Joe (Zurich U.)
We juxtapose global fits of two bottom-up models (an $S_3$ scalar leptoquark model and a ${B_3-L_2}$$Z^\prime$ model) of $b\rightarrow s \mu^+\mu^-$ anomalies to flavour data in order to quantify statistical preference or lack thereof. [...]

Recoil Proton Telescopes and Parallel Plate Avalanche Counters for the $^{235}$U(n,f) cross section measurement relative to H(n,n)H between 10 and 450 MeV neutron energy / n_TOF Collaboration
With the aim of measuring the $^{235}$U(n,f) cross section at the n_TOF facility at CERN over a wide neutron energy range, a detection system consisting of two fission detectors and three detectors for neutron flux determination was realized. [...]
