Sentence examples for pions from inspiring English sources

One, known as a K-short, will decay into two further mesons, called pions.

What did not fit was the discovery, in 1964, that a few K-longs (around a tenth of a percent of them) were decaying into a mere two pions.

(A charm quark is a heavier cousin of the up quark which, together with down quarks, makes up the ordinary protons and neutrons found in atomic nuclei; lest things get too straightforward, the down quark is not simply an up antiquark).D0s and D0-bars are unstable and decay into other short-lived particles called pions and kaons.

(A charm quark is a heavier cousin of the up quark which, together with down quarks, makes up the ordinary protons and neutrons found in atomic nuclei; the down quark is not just an up antiquark, mind you that would be too simple).D0s and D0-bars decay into combinations of other fleeting particles called pions and kaons.

The CDF team think they have found a bit more of it, in particles known as D0-mesons.When a D0-meson decays, it produces daughter particles called pions and kaons.

It decays into three pions, a complex process that takes more time to happen.

Dr Learned and Dr Zee have come up with a design for a particle accelerator that would do the job a good deal more modestly, using another type of subatomic particle, the pion, as an intermediary.

Mesic atom, atom in which one electron is replaced by a negative muon or a negative pion (pi meson).

Some of them, just as in the case of the pion and the muon, are lighter than the proton, but many are more massive.

Meanwhile, studies of cosmic radiation at high altitudes those conducted on mountains or involving the use of balloon-borne photographic plates had revealed the existence of the pi-meson (pion), a particle 273 times as massive as the electron, which disintegrates into the mu-meson (muon), 207 times as massive as the electron, and a neutrino.

In plates exposed at the top of high mountains or sent up in high-altitude balloons, cosmic-ray interactions were recorded, and in 1947 the data revealed the existence of the pion as well as the process whereby it decays into two other particles, an antimuon (mu-meson) and a neutrino.
