Charm quarks were produced almost simultaneously by two teams in November 1974 (see November Revolution) – one at SLAC under Burton Richter, and one at Brookhaven National Laboratory under Samuel Ting. The charm quarks were observed bound with charm antiquarks in mesons. Meer weergeven A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of Meer weergeven The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. The proposal came shortly after Gell-Mann's 1961 formulation of a particle classification system known as the Eightfold Way – or, in more … Meer weergeven Electric charge Quarks have fractional electric charge values – either (−1/3) or (+2/3) times the elementary charge (e), depending on flavor. Up, … Meer weergeven • Physics portal • Color–flavor locking • Koide formula • Nucleon magnetic moment • Preons • Quarkonium Meer weergeven The Standard Model is the theoretical framework describing all the known elementary particles. This model contains six flavors of quarks ( q ), named up ( u ), down ( … Meer weergeven For some time, Gell-Mann was undecided on an actual spelling for the term he intended to coin, until he found the word quark in James Joyce's 1939 book Finnegans Wake: – Three quarks for Muster Mark! Sure he hasn't got … Meer weergeven As described by quantum chromodynamics, the strong interaction between quarks is mediated by gluons, massless vector gauge bosons. … Meer weergeven WebThe up quark was first observed by experiments at the Stanford Linear Accelerator Center in 1968. History [ edit] In the beginnings of particle physics (first half of the 20th century), hadrons such as protons, neutrons and pions were thought to be elementary particles.
