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.

Pion and kaon electromagnetic and gravitational form factors Pion and kaon electromagnetic and gravitational form factors. Journal: European Physical Journal C Published: 2024-02-26 ...

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 ...

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, ...

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 ...

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 ...

Rosemary Fowler discovered the kaon particle during her research in 1948 but gave up her PhD to ... They had already found the pion for which Prof Powell would be awarded the Nobel Prize in ...
