After five years of running at RHIC, and on the eve of the LHC heavy-ion program, we highlight the status of femtoscopic measurements. We emphasize the role interferometry plays in addressing fundamental questions about the state of matter…

The results of the searches for a Higgs boson decaying to down-type fermions are presented using the proton-proton collision data collected by the ATLAS and CMS experiments at the LHC, at a centre-of-mass energy of 7 and 8 TeV. The results…
