Search for new quarks addresses unnaturalness
Why is the observed mass of the Higgs only 125 GeV?
Search for WISPs gains momentum
Interest is growing in new experiments that probe dark-matter candidates such as axions and other very weakly interacting sub-eV particles.
Largest WIMP survey sets new limits
XENON1T is a 3D-imaging liquid-xenon time projection chamber located at Gran Sasso National Laboratory in Italy.
Trigger-level searches for low-mass dijet resonances
Dijet searches look for a resonance in the two-jet invariant mass spectrum.
CMS searches for third-generation leptoquarks
Several phenomenological studies have suggested that anomalies in B decays could be explained by the existence of hypothetical new particles which couple to both leptons and quarks.
CMS hunts for heavy neutral leptons
Through their mixing with the Standard Model neutrinos, sterile Majorana neutrinos could be produced at the LHC in leptonic W-boson decays.
Searches for dark photons at LHCb
While the dark photon does not couple directly to Standard Model particles, quantum-mechanical mixing between the photon and dark-photon fields can generate a small interaction.
ATLAS extends searches for natural supersymmetry
Not only can SUSY accommodate dark matter and gauge–force unification at high energy, it offers a natural explanation for why the Higgs boson is so light compared to the Planck scale.
Majorana neutrinos remain elusive
Neutrinoless double beta-decay is only possible if neutrinos and antineutrinos are identical or “Majorana” particles.
ATLAS hunts for new physics with dibosons
Many Standard Model extensions predict new resonances that can decay into a pair of bosons, for example: VV, Vh, Vγ and γγ.
