Example Sentences
Recent Examples on the Web Three quarks are called a baryon, and consist of a red, blue, and green quark, or an antired, antigreen, and antiblue quark. 
Elizabeth Fernandez, Forbes, 19 Sep. 2021 Astronomers expected these hot baryons to conform to a cosmic superstructure, one made of invisible dark matter, that spanned the immense voids between galaxies. Quanta Magazine, 10 Sep. 2018 The lightest pentaquark has a mass just below the sum of a particular baryon and meson that together contain the correct quark ingredients. Adrian Cho, Science | AAAS, 5 June 2019 By a conventional Standard Model process, the antilepton excess would then have cascaded into a one-part-per-billion excess of baryons (protons and neutrons) over antibaryons. Quanta Magazine, 15 Oct. 2013 That suggests each pentaquark is just a baryon bound to a meson, with a tiny bit of mass taken up in binding energy. Adrian Cho, Science | AAAS, 5 June 2019 The heavier pentaquarks have masses just below the sum of the same baryon and a related meson with extra internal energy. Adrian Cho, Science | AAAS, 5 June 2019 In other words, the ratio of baryons, which include protons and neutrons, to photons, which light is made of, would have to shrink. Charles Q. Choi, Space.com, 26 Sep. 2018 Dark matter makes up about 27 percent of the universe, but scientists know little about it except that it’s not made of normal matter particles called baryons.
