PRACE helps researchers calculate mass difference between neutrons and protons
With the help of PRACE HPC resources, a team of physicists from France, Germany, and Hungary headed by Zoltán Fodor, a researcher from Wuppertal, has successfully calculated the tiny neutron-proton mass difference. The results of this research, published in the 27 March 2015 edition of Science, are considered a milestone by many physicists and confirm the theory of the strong interaction.
