单词	gluon
释义	gluon noun glu·​on ˈglü-ˌän  : a hypothetical neutral massless particle held to bind together quarks to form hadrons Example Sentences Recent Examples on the Web Now, by exploiting a high-precision determination of the quark-gluon content of the proton and by examining 35 years’ worth of data, particle physics data researchers have discovered evidence that the proton does contain intrinsic charm quarks. Robert Lea, Popular Mechanics, 30 Aug. 2022 The team then looked for traces of the charm quark and traced its history of gluon emissions. Robert Lea, Popular Mechanics, 27 June 2022 Is the gluon the source of the heat of nuclear fusion? Scientific American, 1 Feb. 2022 When the Universe reaches a few microseconds in age, a new threshold gets crossed: the temperatures and densities have now dropped low enough that confinement occurs, and what was previously a quark-gluon plasma now becomes full of bound states. Ethan Siegel, Forbes, 2 Sep. 2021 Physicists can now calculate how pressure and density would have evolved from the quark-gluon plasma at the beginning of the universe. Quanta Magazine, 23 Sep. 2020 For example, when a virtual gluon splits into two virtual quarks, the quarks’ possible lifetimes can vary. Quanta Magazine, 20 Aug. 2020 But the golden rule of quantum theory is to consider all possibilities, and exchanging a simple gluon represents just one among a vast landscape of scenarios that could unfold when two quarks collide. Quanta Magazine, 20 Aug. 2020 Instead, quarks and gluons mingled freely in a dense soup until things cooled down sufficiently for protons to condense out of the QGP.
