is one of the most sought-after quantities in particle physics that scientists are one step closer to accurately determining, thanks to a new experiment led by researchers from the Max Planck Institute for Nuclear Physics in Germany.
Being so light, and strange, neutrinos may not play by the same rules as other particles. Adding up the smear of its incredibly small masses with precision may even help confirm and rule out new models in particle physics.However, with no charge and virtually no gravitational pull, neutrinos exert only the faintest of forces on other particles.
Physicists can then measure the total energy released in this decay using a calorimeter of sorts, and infer the mass of the 'missing' neutrino that flew off into the ether based on the total mass of the atom and Einstein's famed equation, E=mc: a difference in energy which can be translated into the mass 'missing' from the sum total of atomic particles after a decay reaction. That difference in mass is interpreted as the neutrino.
