Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

Bind an electron to a reference ion—the team used the “hydrogen-like” carbon nucleus, stripped down to a single electron. The nucleus of that ion has a known, precise mass.

Silver-110’s decay reveals a promising path to measure antineutrino mass. New data could reshape future neutrino studies.

The electron has been weighed with unprecedented precision. Its new and improved mass is 17 times as precise as the previous best estimate.

Unlike most of us, subatomic particles don't gain weight asthey get older. The mass of these tiny bits of matter has remained constantover the last 6 billion years, recent astronomical ...

Precise knowledge of the mass of the electron can thus be of vital assistance in the search for previously unknown physical interrelationships. The team of physicists headed by Klaus Blaum and Sven ...

Over the past few decades, the atomic mass of the electron has been determined using several Penning-trap experiments, because exploration of the scope of validity of the Standard Model requires ...

Using a novel technique, scientists have greatly improved the precision with which they can measure the mass of an electron, a new study reports.

The KATRIN experiment in Germany nearly halved the maximum possible mass for neutrinos, setting it at 0.45 electron volts.

New mass for the electron, in theory 01 Jun 2003 There are about a dozen quantities in atomic and nuclear physics that are fundamental to our current understanding of science. One is the speed of ...
