Researchers close in on the elusive neutrino

The humble neutrino, an elusive subatomic particle that passes effortlessly through normal matter, plays an outsized role among the particles that comprise our universe. To fully explain how our universe came to be, we need ...

When black holes collide they also produce neutrinos

Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able to figure out what generates them. But a new hypothesis suggests an unlikely source: the mergers ...

Search for sterile neutrinos: It's all about a bend in the curve

There are many questions surrounding the elementary particle neutrino, in particular regarding its mass. Physicists are also interested in whether besides the 'classic' neutrinos there are variants such as the so-called sterile ...

Researchers set new upper limit on neutrino mass

An international team of researchers has used a new spectrometer to find and set an upper limit for the mass of a neutrino. In their paper published in the journal Physical Review Letters, the group describes how they came ...

Researchers home in on extremely rare nuclear process

A hypothetical nuclear process known as neutrinoless double beta decay ought to be among the least likely events in the universe. Now the international EXO-200 collaboration, which includes researchers from the Department ...

Scientists shave estimate of neutrino's mass in half

An international team of scientists, including researchers at MIT, has come closer to pinning down the mass of the elusive neutrino. These ghost-like particles permeate the universe and yet are thought to be nearly massless, ...

Major steps forward in understanding neutrino properties

In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory in Italy is looking for signs of neutrinoless double beta decay. The experiment has the greatest ...
