This is where things begin to get strange. Roughly one out of 10 billion times, a positively-charged kaon decays into a positively-charged pion and a neutrino-antineutrino pair.

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...

Physicists have long suspected that pion (π) and kaon (K) particles could stick together to form πK atoms, but no one had ever seen such an exotic particle pairing. It’s rare enough to spot ...

Paul Pion alleged that property owner Damian Krause and prospective purchaser Aaron Appel schemed to portray his family as “squatters” and “hoarders.” ...

BILLERICA, Mass., May 27, 2025--Pion Inc., a leading provider of innovative analytical solutions for drug development, today announced the launch of its latest product, DissoSpec™ QC Dissolution ...

Their primary aim is to make an extremely precise measurement of the probability that a positively charged kaon will decay to a positively charged pion plus a neutrino/antineutrino pair.

Specifically, NA62 will measure the rate at which the charged kaon decays into a charged pion and a neutrino-antineutrino pair.

The kaon can decay into a pion, a neutrino, and an antineutrino. This process is important because it occurs extremely rarely. Indeed, fewer than one kaon in 10 billion decays in this manner.

In particular, the detector can filter the pion-neutrino-antineutrino event from all the other possible decays that the kaon can undergo. The new result suggests that the rare event could occur once ...

The initial particle in the observed decay is a charged kaon, which consists of two elementary quarks. It had been predicted that kaons can decay into a charged pion - also a pair of quarks - and two ...
