Physicists on the CMS experiment announce the most elaborate mass measurement of a particle that is notoriously difficult to study and has captivated the physics community for decades. After an ...

Physicist Björn Lehnert from the Lawrence Berkeley National Laboratory talks to Richard Blaustein about what a new precise measurement of the neutrino means for particle physics Weighty matters: ...

Direct kinematic measurements, which rely solely on energy and momentum conservation in nuclear beta decays, provide the most model-independent approach to this fundamental question. The HOLMES ...

What is the purpose of prescribed practical P4? To investigate experimentally the relationship between the mass and volume of liquids and regular solids, and analyse and interpret the data gathered.
