Physics: A smaller proton, a big challenge

Impact: Nuclear Physics    July 11, 2010
The proton is one of the fundamental components of the atom. For a long time scientists have believed it to be 0.8768 femtometers in size (a femtometer is one quadrillionth of a meter). Now, it looks like they may have been wrong, the size is 0.84184 femtometers. In a way, the discrepancy is very small…as [...]

A neutrino oscillates, wounds Standard Model

News: Nuclear Physics    June 3, 2010
This piece of news, the importance of which is disguised by the colorful name chameleon neutrino, should start with the concluding paragraph of the press release from CERN, the European nuclear studies center: While closing a chapter on understanding the nature of neutrinos, the observation of neutrino oscillations is strong evidence for new physics. In [...]
