Maximum Mass of Lightest Neutrino

Authors: George Rajna

Neutrinos come in three flavours made up of a mix of three neutrino masses. While the differences between the masses are known, little information was available about the mass of the lightest species until now. [19] Nuclear physicists successfully measured the weak charge of the proton by shooting electrons at a cold liquid hydrogen target in an experiment carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility. [18] The IceCube Neutrino Observatory in Antarctica is about to get a significant upgrade. [17] While these experiments seem miniature in comparison to others, they could reveal answers about neutrinos that have been hiding from physicists for decades. [16] In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson.
