Other scientists had previously suggested that this isotope would be a good candidate for studying electron capture as an analog to measuring neutrino mass. In electron capture, the heavier ...

The KATRIN experiment’s best result found an upper neutrino mass limit of 0.8 electronvolts, making it roughly 500,000 times smaller than the mass of an electron. This measurement can also be ...

The lab was measuring the electron neutrinos that come directly from the sun ... These conclusions have posed many other questions for particle physicists. What is the mass of a neutrino? Why are ...

These particles are so ghostly that trillions of them pass through Earth each day without notice. So, how do we detect them?

When this happens, an electron in the beryllium atom ... If it is too small, then the three different types of neutrino, each of a different mass, will spill over the edges of the neutrino wave ...

Now we know that neutrinos are not massless, and that the three flavours mix so that a neutrino produced as electron type can subsequently interact as muon or tau type. We do not know for sure that ...

These neutrino oscillation parameters are fundamental physical constants in the same way that the mass and charge of the electron are fundamental. Neutrino research, because of the scale, cost and ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a ...

The Tokai-to-Kamioka (T2K) long-baseline neutrino experiment measures neutrino oscillations over a baseline of 295 km using a ...

Rutherford also put out the idea that there could be a particle with mass but no charge. He called it a neutron, and imagined it as a paired proton and electron. There was no evidence for any of ...

Neutrinos may be the key to quantum gravity, potentially leading to a unified theory combining quantum mechanics and general relativity.

Neutrinos are the least understood of the currently known elementary particles. They have a nearly negligible mass and they rarely interact, yet they are extremely abundant and have had a significant ...
