Observational first: physicists have used the ATLAS experiment at CERN to observe the production of top-quark and photon pairs. (Courtesy: CERN) For the first time, particle physicists have observed ...

What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you, I'm ...

During a deeply inelastic collision with a proton, a relativistic electron (highlighted in blue) can emit a high-energy photon (purple here) that penetrates interior of the proton, where it ‘sees’ ...

A team of physicists has embarked on a journey where few others have gone: into the glue that binds atomic nuclei. The resultant measurement, which was extracted from experimental data taken at the ...

GlueX The spectrometer at Jefferson Lab was used to study the behaviour of gluons within nuclei. (Courtesy: Jefferson Lab/Aileen Devlin) A new experiment has offered the clearest view yet of how ...

An analysis by physicists of colliding protons is tackling the mystery of where protons get their intrinsic property known as spin. Along with neutrons, protons are housed inside an atom's nucleus.

There’s a pencil lying on my desk right now. It’s not much to look at, but what if I could zoom way in and see the protons and other itty-bitty stuff inside it? My friend Ryan Corbin told me it would ...

(Nanowerk News) The world’s largest and most powerful particle accelerator may be producing the world’s tiniest droplets of liquid, right under scientists’ noses. Researchers supported by the ...

Calculations of charge distribution in mesons provide benchmark for experimental measurements and validate widely used 'factorization' method for imaging the building blocks of matter. Nuclear physics ...
