Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a "sterile" type of neutrino hypothesized ...

The Big Bang created equal amounts of matter and antimatter. So, why is there so much more matter than antimatter in the Universe? Irfu is participating in the preparation of Hyper-Kamiokande, a ...

Countless neutrinos fly through you every second! Neutrinos, a category of leptons, have no electric charge and do not feel the strong interactions that bind the quarks into protons and neutrons.

The results add to physicists’ understanding of neutrinos and validate collaboration between major experiments. The NOνA far detector. Credit: Public domain image from Fermilab. More details here.
