Since the flavor of a neutrino depends on its phase, the flavor can change over time. This phenomenon is called a neutrino oscillation, the metamorphosis of a neutrino of one flavor to a neutrino of 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 ...

In 2009, the Japanese Kamland experiment achieved an important finding: it incontestably confirmed the transformation of a type of neutrino into another, a phenomenon that physicists call flavor ...

Particle physicists have been looking for so-called "sterile neutrinos" for a few decades now. They are a hypothesized ...

If so, learning more about the masses and oscillations of neutrinos and ... scientists should be able to compare the mix of neutrino flavors at the start and end of their journey.
