Twelve of the 17 Standard-Model particles are the ingredients of matter.

However, scientists are already discussing the other facilities that will be needed to complete the search for the new physics that must exist beyond the current Standard Model of particles and their interactions.
Without it, or something like it, some of the Standard Model's particles that actually do have mass (particularly the W and Z bosons) would be predicted to be massless.
According to the standard model these six particles (the flavoured neutrinos and the corresponding electron-like particles) together with another six, the quarks (which make up the protons and neutrons in atomic nuclei), are the irreducible units from which the rest of matter is composed.
These are like the particles in the Standard Model - but more massive.
So far, the theorists have described how three of the 16 particles in the Standard Model of particle physics may be created in this way.
Since then, all the particles predicted by the Standard Model have been discovered - including most recently the Higgs.
What's more, physicists are still finalizing the standard model, the theory behind particles.

The Standard Model (see table) includes familiar particles such as electrons and photons, and esoteric ones like the W and Z bosons, which carry something called the weak nuclear force.
Just as all the known particles of matter have antimatter versions in the Standard Model, in the world of susy every known boson, including the Higgs, has one or more fermion partners, and every known fermion has one or more associated bosons.

The Standard Model is a framework that explains how the known sub-atomic particles interact with each other.
The probable discovery added a final missing piece to the framework known as the Standard Model, which stands as the most widely accepted theory to explain how particles of matter interact.

Our best understanding of physics so far, called the Standard Model, suggests that the complicated cascades of decay of D-mesons into other particles should be very nearly the same - within less than 0.1% - as a similar chain of antimatter decays.
These particles boost storage densities to as high as 150 gigabits per square inch from the current standard of 35 gigabits per square inch.
