Probing Neutral Triple Gauge Couplings via $\boldsymbol{Z\gamma\,(\ell^+\ell^-\gamma)}$ Production at $\boldsymbol{e^+e^-}$ Colliders / Liu, Danning (Shanghai Jiao Tong U.) ; Xiao, Rui-Qing (Shanghai Jiao Tong U. ; King's Coll. London) ; Li, Shu (Shanghai Jiao Tong U. ; Maryland U. ; Peking U., CHEP) ; Ellis, John (Shanghai Jiao Tong U. ; King's Coll. London ; CERN) ; He, Hong-Jian (Shanghai Jiao Tong U. ; Peking U., CHEP) ; Yuan, Rui (Shanghai Jiao Tong U.)
Neutral triple gauge couplings (nTGCs) are absent in the Standard Model (SM) and at the dimension-6 level in the Standard Model Effective Field Theory (SMEFT), arising first from dimension-8 operators. [...]

Benchmark of deep-inelastic-scattering structure functions at $\mathcal{O}(\alpha_s^3)$ / Bertone, Valerio (IRFU, Saclay) ; Karlberg, Alexander (CERN)
We present a benchmark comparison of the massless inclusive deep-inelastic-scattering (DIS) structure functions up to $\mathcal{O}(\alpha_s^3)$ in perturbative QCD. [...]

Measurement of multijet azimuthal correlations and determination of the strong coupling in proton-proton collisions at $ \sqrt{s}= $ 13 TeV / CMS Collaboration
A measurement is presented of a ratio observable that provides a measure of the azimuthal correlations among jets with large transverse momentum $ p_{\mathrm{T}} $. [...]

(Manchester U.) ; Garcia Ruiz, R.F. (MIT ; CERN) et al.
Collinear laser spectroscopy measurements were performed on $^{68-74}$Ge isotopes ($Z = 32$) at ISOLDE-CERN, by probing the $4s^2 4p^2 \, ^3\!P_1 \rightarrow 4s^2 4p 5s \, ^3\!P_1^o$ atomic transition (269~nm) of germanium. [...]
