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.
