Deeper insight into Higgs boson production using W bosons

Discovering the Higgs boson in 2012 was only the start. Physicists immediately began measuring its properties, an investigation that is still ongoing as they try to unravel if the Higgs mechanism is realized in nature as ...

Under the radar: Searching for stealthy supersymmetry

The standard model of particle physics encapsulates our current knowledge of elementary particles and their interactions. The standard model is not complete; for example, it does not describe observations such as gravity, ...

New insight into mammalian stem cell evolution

The genes regulating pluripotent stem cells in mammals are surprisingly similar across 48 species, Kyoto University researchers report in the journal Genome Biology and Evolution. The study also shows that differences among ...

Defining geographic regions with commuter data

A new mathematical approach uses data on people's commutes between and within U.S. counties to identify important geographic regions. Mark He of the University of North Carolina at Chapel Hill and colleagues present this ...

Accelerating the grapevine effect

Gossip is an efficient way to share information across large networks and has unexpected applications in solving other mathematical and machine-learning problems.

ATLAS experiment observes light scattering off light

Light-by-light scattering is a very rare phenomenon in which two photons interact, producing another pair of photons. This process was among the earliest predictions of quantum electrodynamics (QED), the quantum theory of ...
