Charged kaons — the subject of the experiment — contain an up quark and an anti-strange quark. Without getting too far into the weeds, what you need to know is that in the ultra-rare decay the ...

Kaons, also known as K mesons, are made of two quarks. Charged kaons — the subject of the experiment — contain an up quark and an anti-strange quark. Without getting too far into the weeds, what you ...

Guest host Rob Schmitz speaks with cookbook author Luisa Weiss about her upcoming book, Classic German Cooking.

with one being produced by a gluon radiated by a quark-antiquark pair. Physicists love a particle accelerator, and we have since taken a good look at the six flavors of quarks (up, down, strange, ...

In the present study, Cheng, Feng, and Huang elaborated on this idea, analysing a model where the particle is composed of a K meson, which contains a strange antiquark and a light quark (either up or ...

are strange (and sometimes anti-strange) beasts. Protons and neutrons are usually made up of three quarks. For protons that's two up quarks and one down quark, for neutrons, it's one up quark and ...
