The new calculation gives a more accurate prediction for the likelihood with which kaons decay into a pair of electrically charged pions vs. a pair of neutral pions. Share: Facebook Twitter ...

What was observed was the decay of a subatomic particle known as a kaon into two other particles called pions. Kaons and pions (and many other particles as well) are composed of quarks.

To measure this kaon decay, the NA62 experiment was specifically designed and built. ... It is estimated that roughly 13 in 100 billion kaons decay into a pion and two neutrinos.

Rosemary Fowler discovered a type of subatomic particle, the kaon—but left the university before earning her doctorate.

The NA62 collaboration presented at a CERN EP seminar the first experimental observation of the ultra-rare decay of the charged kaon into a charged pion and a neutrino-antineutrino pair (K + → ...

The kaon, a special case of meson particle, is made of one quark and one antiquark. All are part of the overall family called hadrons. When kaon particles decay, a very rare few undergo a change ...

As part of an experiment called NA62, researchers detected and measured an ultra-rare form of decay for a subatomic particle called a kaon. This is one of the rarest interactions in particle ...

Physicists predict that from these kaons, roughly one in 10 billion will decay into a positively-charged pion a neutrino/antineutrino pair. And now, they’ve successfully detected it.

In the ultrarare decay, a kaon produces another particle called a pion, alongside two lightweight, electrically neutral particles: a neutrino and its antimatter counterpart, an antineutrino.

In one scenario, they suggest that the Kaon might decay into a pion -- a subatomic particle with a mass about 270 times that of an electron -- and some sort of invisible particle.
