When a particle is transformed into its antiparticle and its spatial coordinates inverted, the laws of physics are required to stay the same—or so we thought. This symmetry—known as CP symmetry (charge conjugation and ...

Two years ago, the Higgs boson was observed decaying to a pair of beauty quarks (H→bb), moving its study from the "discovery era" to the "measurement era." By measuring the properties of the Higgs boson and comparing them ...

A quarter-century after its discovery, physicists at the ATLAS Experiment at CERN are gaining new insight into the heaviest-known particle, the top quark. The huge amount of data collected during Run 2 of the LHC (2015-2018) ...

In new results presented at CERN, the ATLAS Experiment's search for supersymmetry (SUSY) reached new levels of sensitivity. The results examine a popular SUSY extension studied at the Large Hadron Collider (LHC): the "Minimal ...

What if you could test a new theory against data from the Large Hadron Collider (LHC)? Better yet, what if the expert knowledge needed to do this was captured in a convenient format? This tall order is now on its way from ...

At the Large Hadron Collider (LHC) at CERN, the electromagnetic fields of Lorentz-contracted lead nuclei in heavy-ion collisions act as intense sources of high-energy photons, or particles of light. This environment allows ...

New particles sensitive to the strong interaction might be produced in abundance in the proton-proton collisions generated by the Large Hadron Collider (LHC) – provided that they aren't too heavy. These particles could ...

As the heaviest known particle, the top quark plays a key role in studies of fundamental interactions. Due to its short lifetime, the top quark decays before it can turn into a hadron. Thus, its properties are preserved and ...
