7061por Viel, Simon“…Indeed, theoretical problems such as the hierarchy of energy scales, the Higgs mass fine-tuning and the large number of postulated parameters need to be addressed, while the experimental observations of dark matter, dark energy and neutrino masses are not explained by the Standard Model. …”

7064por Tornambe, Peter“…If R-parity is conserved, SUSY particles are produced in pairs and the lightest supersymmetric particle (LSP), which is typically the lightest neutrino $\tilde{\chi}_1^0$, is stable. In many models the LSP can be a suitable candidate for dark matter. …”

7068por Karthein, Jonas“…The result reduced the uncertainty on the $Q_{EC}$-value of the $^{131}$Cs → $^{131}$Xe decay by a factor of 25 and consequently precluded the decay as a possible candidate for a direct neutrino-mass determination. Third, ultra-high mass resolving powers exceeding 10$^6$ using PI-ICR allowed for the first spatial resolution of isomeric states in neutron-rich cadmium isotopes. …”

While the performance of superconducting RF (SRF) cavities has improved significantly over the last decades, and the SRF technology has enabled new applications, the proposed HEP facilities and experiments pose new challenges. …”

7071por Macdonell, Danika Marina“…The search targets a final state topology in which dark matter is produced from the proton-proton collisions in association with a pair of W bosons, one of which decays to a pair of quarks and the other to a lepton-neutrino pair. The dark matter is expected to pass invisibly through the detector, resulting in an imbalance of momentum in the plane transverse to the beam line. …”

The extraction septum magnets actually used at the SPS have been designed for slow extraction over several seconds, have large cooling and electrical power demands and need frequently maintenance in a high radiation environment.…”

The search is performed with the ATLAS detector at the LHC using data collected in proton–proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV and corresponding to an integrated luminosity of 36.1 fb$^{-1}$. …”
