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.

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.

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 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 ...

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.

Cantor Fitzgerald exec Paul Pion was last month accused of squatting in a Hamptons mansion—but he now claims the owner is harassing him and embarrassing him in an effort to force him out. Pion ...

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

Paul Pion, chief administration officer at the financial firm Cantor Fitzgerald, and his wife, Stephanie, have reportedly been renting the $5m home in Water Mill, Long Island for the past two years.
