HAWC and other high-altitude observatories are pushing the energy of gamma-ray observations into new territory to test fundamental symmetries.
LHCb results favour the interpretation of the state as a quasi-bound D0D*0 molecule, but other possibilities cannot yet be ruled o...
A novel technique by ATLAS uses top-quark pairs to test the ratio of the probabilities for tau leptons and muons to be produced in W-boson decays
The latest spectral measurements of antihydrogen atoms confirm that a key portion of QED holds up in both matter and antimatter.
A challenge for such searches is that the masses of the supersymmetric particles are unknown, leaving a large range of possibilities to explore.
CMS has made a novel measurement of the top-quark mass by reconstructing boosted top quarks as single jets.
A new ATLAS analysis cuts a swathe into the parameter space for one well-motivated alternative electroweak symmetry breaking sector.
CMS has probed the running of the mass of the top quark for the first time - an important test of the validity of QCD, and an indirect search for unknown physics.
Jet modification effects are predicted to be strongest in this kinematic region.
LHCb will soon become the first LHC experiment able to run simultaneously with two separate interaction regions.
