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.

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.

Specifically, NA62 will measure the rate at which the charged kaon decays into a charged pion and a neutrino-antineutrino pair. This process is one of the rarest among meson decays, ...

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.

The kaons next encounter the Gigatracker, which is a silicon pixel detector that measures the momentum of each kaon to a high precision. This precision is needed to match the “mother” kaon to the ...

K mesons or kaons are unstable and can decay in a number of ways. In one important but very rare decay, a positive kaon – a bound state of an up quark and a strange antiquark — decays into a positive ...
