High-energy hadron colliders with multi-TeV centre-of-mass energies require high-field superconducting magnets. Examples include the large hadron collider (LHC) and its high-luminosity upgrade (HL-LHC), as well as future projects such as the future circular collider (FCC-hh) and super proton–proton collider (SPPC).

Searches for Lepton Number Violation and Resonances in the $K^{\pm}\to \mu\nu\nu$ Decays by NA48/2 at CERN / Zinchenko, A (Dubna, JINR) /NA48/2 Collaboration
The NA48/2 experiment at CERN collected a large sample of charged kaon decays into final states with multiple charged particles in 2003–2004. A new upper limit on the rate of the lepton number violating decay → \(\pi ^{ \mp }\)µ^±µ^± obtained from this sample is reported: B(K^± → \(\pi ^{ \mp }\)µ^±µ^±) < 8.6 × 10^−11 at 90% CL. [...]

Search for the rare decays $W^{+}\rightarrow{D^{+}_{s}\gamma}$ and $Z\rightarrow{D^{0}\gamma}$ at LHCb / LHCb Collaboration
A search for the rare decays $W^{+}\rightarrow{D^{+}_{s}\gamma}$ and $Z\rightarrow{D^{0}\gamma}$ is performed using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 2.0 $\textrm{fb}^{-1}$. No significant signal is observed for either decay mode and upper limits on their branching fractions are set using $W^{+}\rightarrow{\mu^{+}\nu}$ and $Z\rightarrow{\mu^{+}\mu^{-}}$ decays as normalization channels.

Search for Higgs boson Decays to Beyond-the-Standard-Model Light Bosons in Four-Lepton Final States with the ATLAS Detector at the LHC / Soumaimi, Zainab (Rabat U.) ; Boye, Diallo (Johannesburg U.) ; Fassi, Farida (Rabat U.) ; Assamagan, Ketevi (Brookhaven) ; Connell, Simon (Johannesburg U.) ; Weber, Christian (Brookhaven)
Hidden sector or dark sector states appear in many extensions to the Standard Model (SM), to provide particle mediators for dark matter in the universe. A new probe of this hypothetical hidden or dark sector may have become available at the energy frontier opened up by the LHC with the Higgs boson and its distinct couplings to SM particles. [...]

New limits on heavy neutrinos from Kaon experiments at CERN / Massri, Karim (CERN)
The NA48/2 and NA62-$R_K$ experiments at CERN collected large samples of charged kaon decays in 2003--2004 and 2007, respectively. These samples, collected with different trigger conditions, allow to search for both short and long-living heavy neutrinos produced in $K^{\pm}\to\mu^{\pm}N_4$ decays. [...]

Recent results from NA48/2 and NA62 experiments at CERN / Lurkin, Nicolas (Birmingham U.)
The NA48/2 and $\text{NA62}\text{-}{\text{R}_\text{K}}$ experiments at the CERN SPS collected a large sample of charged kaon decays in flight. $\text{NA62}\text{-}{\text{R}_\text{K}}$ was running in 2007-08 with a highly efficient minimum bias trigger for decays into electrons. [...]

Measurement of the $B^0_s\to\mu^+\mu^-$ branching fraction and effective lifetime and search for $B^0\to\mu^+\mu^-$ decays / LHCb Collaboration
A search for the rare decays $B^0_s\to\mu^+\mu^-$ and $B^0\to\mu^+\mu^-$ is performed at the LHCb experiment using data collected in $pp$ collisions corresponding to a total integrated luminosity of 4.4 fb$^{-1}$. An excess of $B^0_s\to\mu^+\mu^-$ decays is observed with a significance of 7.8 standard deviations, representing the first observation of this decay in a single experiment. [...]

Search for anomalous couplings in boosted $\mathrm{ WW/WZ }\to\ell\nu\mathrm{ q \bar{q} }$ production in proton-proton collisions at $\sqrt{s} =$ 8 TeV / CMS Collaboration
This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton-proton collisions. The search is performed using events containing a W boson that decays leptonically and a W or Z boson whose decay products are merged into a single reconstructed jet. [...]

Search for associated production of dark matter with a Higgs boson decaying to $ \mathrm{b}\overline{\mathrm{b}} $ or $\gamma \gamma$ at $ \sqrt{s}=13$ TeV / CMS Collaboration
A search for dark matter is performed using events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons. The data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected in 2015 with the CMS detector at the LHC, correspond to an integrated luminosity of 2.3 inverse femtobarns.

Measurements of electroweak $Wjj$ production and constraints on anomalous gauge couplings with the ATLAS detector / ATLAS Collaboration
Measurements of the electroweak production of a $W$ boson in association with two jets at high dijet invariant mass are performed using $\sqrt{s} = 7$ and $8$ TeV proton--proton collision data produced by the Large Hadron Collider, corresponding respectively to 4.7 and 20.2 fb$^{-1}$ of integrated luminosity collected by the ATLAS detector. The measurements are sensitive to the production of a $W$ boson via a triple-gauge-boson vertex and include both the fiducial and differential cross sections of the electroweak process..
