Examples of supersymmetry in a Sentence

Recent Examples on the Web Finally, there is the news—or lack thereof—from the latest particle accelerators, which have not found any evidence for the extra particles predicted by supersymmetry, an idea that string theory relies on. Adam Becker, Scientific American, 20 Jan. 2022 Beautiful, all-encompassing theories such as supersymmetry, which predicts a complete set of mirror-image particles for all the ones in the Standard Model, were in vogue; the subtleties of neutrino oscillations were not. Quanta Magazine, 28 Oct. 2021 The Large Hadron Collider, the first of its kind powerful enough to detect the supersymmetry particles required for String Theory to hang together, has found nothing of the like. Ginny Whitelaw, Forbes, 1 Oct. 2021 One possibility is that an extension of the standard model, called supersymmetry, is true. Don Lincoln, Forbes, 7 Apr. 2021 In 2003 signs of supersymmetry—a conjectured extension of the Standard Model that introduces new particles—were seen at LEP, also at around three sigma. Sabine Hossenfelder, Scientific American, 7 Apr. 2021 As the name of the article implies, interest in the octonions has been rekindled by their surprising relationship to recent developments in theoretical physics, including supersymmetry, string theory and M-theory. Michael Moyer, Scientific American, 4 May 2011 Loeb points out that many of the most fashionable research topics in physics — other than supersymmetry, ideas like extra-spatial dimensions, string theory, multiverses — lack much experimental backing. Farhad Manjoo New York Times, Star Tribune, 12 Feb. 2021 Even though none of them turned up, that has ended up being informative, killing off a huge range of potential models for other particles and causing plenty of people to rethink models based on the idea of supersymmetry.
