Working on my next block for #PrinterSolstice for the prompt “even.” This is particle physicist Bibha Chowdhuri (1913-1991) known for her work on cosmic rays, which were the primary way physicists could study particle physics before particl
CP Violation in Baryons I was (pleasantly) surprised to learn a few weeks ago that I shall be teaching particle physics again next academic year. That means that I’ll have to update to the notes to reflect the latest news from CERN. Researc
#CMSPaper 1199: Many quark combinations make #mesons, particles composed of a quark+antiquark. This paper measures how B mesons form; these contain bottom (or: #beauty) quarks plus one other (lighter) quark. Conclusion: the production is sl
What “mesons” means
WikipediaIn particle physics, a meson is a type of hadronic subatomic particle composed of an equal number of quarks and antiquarks, usually one of each, bound together by the strong interaction. Because mesons are composed of quark subparticles, they have a meaningful physical size, a diameter of roughly one femtometre (10−15 m), which is about 0.6 times the size of a proton or neutron. All mesons are unstable, with the longest-lived lasting for only a few tenths of a nanosecond. Heavier mesons decay to
