Quarcum lepor,? vel quarcum c,[1] omnium quarcorum est tertium e maxime massvo, quasi particula elementaris, et magna materiei pars. Quarca lepor in hadrona appellatis inveniuntur, quae particulae subatomicae in quarcis consistentes sunt. Inter hadrona quae quarca mira continent sunt meson J/ψ, mesona D, baryona mirifica sigma, aliaeque particulae mirae.

Quarcum lepor, cum quarco miro, est pars secundae materiei aetatis, atque onus electricum +2/3 e? et massam nudam 95+9
−3 MeV/c2.? habet.[2] Quarcum lepor, sicut omnia quarca, est fermion elementare cui est versus 1/2,? et quod omnes quattuor vires fundamentales[3] patitur, quae sunt gravitatio, electromagnetismus, vires debiles, et vires fortes. Antiparticula quarci leporis est antiquarcum lepor,[4] quod ab eo differt solum quod nonnullae ex eius proprietatibus, sicut onus electricum, magnitudinem aequam sed signum oppositum exhibent.

Exsistentia quarci quarti a nonnullis auctoribus circa 1964 excogitabatur, exempli gratia a Iacobo Bjorken et Sheldon Lee Glashow[5]), sed a Sheldon Lee Glashow, Ioanne Iliopoulos, et Luciano Maiani anno 1970 certe praedicta est.[6] Glashow ipse sic dixit: "Nostrum constructum 'quarcum mirum' nominabamus, nam a symmetria quam in mundum subnuclearem ferebat fascinabamur et oblectabamur."[7][8] Prima particula fascinata (particula quarcum leporem continens) nota erat meson J/ψ, quam anno 1974 manus investigatorum invenerunt apud Sedem Acceleratoris Linearis Stanfordiensem in California, Burtono Richter duce,[9] atque adeo apud Laboratorium Nationale Brookhavenense in Novo Eboraco, Samuele Ting duce.[10]

J/Psi particula subatomica anno 1974 inventum (et ergo quarcum lepor inventum) multas coepit res gestas magni momenti, quae Res Novae Novembres una appellantur.

Hadrona quae quarca lepores continent

[recensere | fontem recensere]

Nonnulla hadrona quarca lepores continent.

  • Mesona D quarcum leporem (aut eius antiparticulam) et quarcum sursum aut deorsum continent.
  • Mesona D mirus quarcum leporem et quarcum mirum continent.
  • Sunt multi status charmonia dicti, exempli gratia particulae J/Psi, quae in quarco lepore et eius antiparticula consistunt.
  • Baryona mira observata sunt, et nomina per analogiam cum baryonis miris ferunt, exempli gratia particula lambda+ miro.
