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 ...

Neutrino oscillations, a quantum phenomenon in which neutrinos change their flavour during propagation, have long intrigued physicists due to their role in elucidating the mass hierarchy and ...

The Big Bang created equal amounts of matter and antimatter. So, why is there so much more matter than antimatter in the Universe? Irfu is participating in the preparation of Hyper-Kamiokande, a ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

On July 21, 2000, the DONUT collaboration at Fermilab announced the detection of tau neutrinos for the first time. Here are a few ideas for celebrating 25 years of the most elusive of elusive ...

Deep beneath southern China, JUNO has launched one of the most ambitious neutrino experiments in history. With its massive 20,000-ton liquid scintillator detector now operational, it’s poised to ...

At the foot of the thickly forested Dashi Hill, in southern China’s Guangdong province, pre-approved visitors can take a ride aboard a unique yellow train. Rather than winding through the serene ...

To say that neutrinos aren’t the easiest particles to study would be a bit of an understatement. Outside of dark matter, there’s not much in particle physics that is as slippery as the elusive “ghost ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
