Read article '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.
Read article '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.
Read article 'Majorana neutrinos remain elusive'
Neutrinoless double beta-decay is only possible if neutrinos and antineutrinos are identical or “Majorana” particles.
Read article '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.
Read article 'CAST experiment constrains solar axions'
The CERN Axion Solar Telescope has reported important new exclusion limits on coupling of axions to photons.
Read article 'ATLAS explores the energy frontier'
Utilising pairs of jets (dijets), a recent ATLAS search was able to probe the highest invariant mass of any of its searches, measuring events with energies as high as 8.1 TeV.
Read article 'SUSY searches in the electroweak sector'
CMS has recently reported searches for electroweak production of neutralinos and charginos in different final states.
Read article 'ATLAS pushes SUSY beyond 2 TeV'
The strongly produced partners of the gluon and quarks, the gluino and squarks, would decay to final states containing energetic jets, possibly leptons, and two LSPs.

A 100 km-circumference collider would address many of the outstanding questions in modern particle physics.
