• An elementary particle is a particle that is not made up of any smaller particles. Elementary particles are quarks, leptons, and bosons. These particles then join to create the more well-known particles, such as the neutron and the proton. Gauge bosons are force carriers. Protons and neutrons, as well as other particles, are baryons.

  • Elementary particles are the smallest known building blocks of the universe. They made atoms of extremely tiny particles called protons, neutrons, and electrons.
  • Particles and antiparticles pop in and out of existence all the time. Some we know about, and many remain undiscovered.
  • Things that happen in the particle zoo can’t be random:
  • Gamma rays are the pond ripples of nuclear physics.
  • Protons are rare decay particles. Fermions are the building blocks of matter.Neutrinos are leptons.
  • The volume of the sun nearest to the surface is 75% hydrogen, and 25% is composed of ionized hydrogen plasma.
  • You get 2 or 3 neutrons from each uranium fission involving 235 nucleons, but you get one or two from every fusion involving six particles.
  • Protons, neutrons, pions, and hadrons have mass. Protons are profoundly stable, while neutrons, on their own, have a life expectancy of only about 611 seconds. Both are composite particles.

  • A neutral neutron decays into a positively charged proton, a negative electron, and a neutral anti-electron-neutrino. Both contain three valence quarks. The proton contains two up quarks and a down quark. The neutron has two down quarks and an up quark. Life could not exist if the neutron weighed a little less. A proton is about 1,835 times more massive than an electron. Neutrons are slightly heavier than protons because they are protons with an electron embedded which cancels out the charge.
  • We divided the observed particles into two major classes: the material particles and the gauge bosons. We know of 150 particles. A particle’s most important characteristics are its mass, electric charge, spin, and interactionsPreons are point particles, conceived as subcomponents of quarks and leptons. Preons come in four varieties, plus, anti-plus, zero, and anti-zero. W-bosons have six preons, while quarks have only 3.
  • gluon is an elementary particle that acts as the exchange particle (or gauge boson) for the strong- force between quarks. Gluons bind quarks together, forming hadrons such as protons and neutrons. Gluons are vector gauge bosons that mediate the strong interactions of quarks in quantum chromodynamics (QCD).
  • In physics, the C parity or charge parity is a multiplicative quantum number of some particles that describes their behavior under the symmetry operation of charge conjugation. Charge symmetry breaking happens under the right conditions. One effect of this charge symmetry violation is that the neutron is slightly heavier than its charged partner, the proton. Parity symmetry means we could flip the universe right-to-left as a mirror, and nothing would change. 
  • A Lack of Symmetry | by Brian Koberlein
  •  Time is non-symmetric or asymmetric.
  • Charge symmetry means swapping all the universe’s positive charges for negative charges and vice versa, changing nothing important.
