Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly ...

You can say the universe has a split personality. Or better said, our physical models of the universe are the ones fractured.

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

An experiment nearly two decades in the making has finally unveiled its measurements of the mass of the universe’s most abundant matter particle: the neutrino. The neutrino could be the weirdest ...

Neutrino physics remains a pivotal area in the quest to unravel fundamental aspects of particle behaviour and the evolution of the universe. Neutrinos—elusive, nearly massless particles—are known to ...

Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research ...

An experiment being built at the Gran Sasso laboratory in Italy could provide valuable insights into neutrino physics and the nature of dark matter. Ettore Fiorini of Milan University and colleagues ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

In December, 1930, a group of physicists convened a meeting in Tübingen, Germany to discuss the latest developments in nuclear physics. A logical person to have at such a meeting would've been ...

An extensive search for a hypothetical particle has turned up empty. The sterile neutrino is a proposed subatomic particle that could even be a candidate for the mysterious dark matter, and although ...

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...

CHAMPAIGN, Ill. — An international team of nuclear physicists has determined that particles called strange quarks do, indeed, contribute to the ordinary properties of the proton. Quarks are subatomic ...
