Physicists have shone a light, so to speak, on a key missing value for neutrino mass. The highly magnetic element holmium was trapped and subjected to mass spectrometry. Reducing the range of the ...

Physicists have taken one small-but-consequential step toward measuring the mass of an elusive "ghost particle" called a neutrino — an achievement that could poke a significant hole in the ...

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

Throughout school and in any physics class, students are told that nothing travels faster than the speed of light. However, that statement might no longer be true because of the neutrino—the particle ...

Harvard astronomer Avi Loeb discusses how scientists trace the cosmic journey of high-energy neutrinos from the Big Bang to ...

Countless neutrinos fly through you every second! Neutrinos, a category of leptons, have no electric charge and do not feel the strong interactions that bind the quarks into protons and neutrons.

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 ...

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 ...

In Sheffield, we study the way that neutrino flavours mix as the neutrinos travel from their birthplace, an effect known as neutrino oscillation. Uncharged, almost massless, and feeling only the weak ...
