It remains to be seen in other meson decays and in decays of other types of particles, such as three-quark particles called baryons. In two new articles posted to the arXiv preprint server ...

The gray spheres show the pattern of the "baryon acoustic oscillations" from the early Universe. Galaxies today have a slight tendency to align on the spheres -- the alignment is greatly ...

They found that normal matter (made of familiar particles like protons and neutrons, collectively called baryons) makes up about 4 to 5 percent of the cosmos’ total energy density. (The ...
