Interest in preon models peaked in the 1980s but has slowed, as the Standard Model of particle physics continues to describe physics mostly successfully, and no direct experimental evidence for lepton and quark compositeness has been found. Preons come in four varieties: plus, anti-plus, zero, and anti-zero.
Strangelet, hypothetical particle that could form matter consisting of strange quarks. R-hadron, bound particle of a quark and a supersymmetric particle. T meson, hypothetical mesons composed of a top quark and one additional subatomic particle. Examples include the theta meson, formed by a top and an anti-top.
The Standard Model of particle physics contains 12 flavors of elementary fermions, plus their corresponding antiparticles, as well as elementary bosons that mediate the forces and the Higgs boson, which was reported on July 4, 2012, as having been likely detected by the two main experiments at the Large Hadron Collider (ATLAS and CMS). [1]
This also means it is the first elementary scalar particle discovered in nature. Elementary bosons responsible for the four fundamental forces of nature are called force particles ( gauge bosons ). The strong interaction is mediated by the gluon , the weak interaction is mediated by the W and Z bosons, electromagnetism by the photon, and ...
The Harari–Shupe preon model (also known as rishon model, RM) is the earliest effort to develop a preon model to explain the phenomena appearing in the Standard Model (SM) of particle physics. [1] It was first developed independently by Haim Harari and by Michael A. Shupe [2] and later expanded by Harari and his then-student Nathan Seiberg. [3]
Untuk konsensus terakhir, silakan buka situs web Particle Data Group di bawah. Română: Modelul standard al particulelor fundamentale: 12 fermioni (6 cuarcuri și 6 leptoni) la care se adaugă tot atâtea antiparticule corespondente și 12 particule de etalonare (bosoni), și anume 3 bosoni vector slabi (W + , W - și Z 0 ), 8 gluoni ...
