Single Idea 21206

[filed under theme 27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties ]

Full Idea

In quantum theory, the full set of quantum numbers defines the state of the particle and, along with its mass, determines its properties.

Gist of Idea

The properties of a particle are determined by its quantum numbers and its mass

The 14 ideas from 'Particle Physics'

A 'field' is just a region to which points can be assigned in space and time [Martin,BR]
The strong force has a considerably greater range than the weak force [Martin,BR]
Many physicists believe particles have further structure, if only we could see it [Martin,BR]
Uncertainty allows very brief violations of energy conservation - even shorter with higher energies [Martin,BR]
The standard model combines theories of strong interaction, and electromagnetic and weak interaction [Martin,BR]
An 'element' is what cannot be decomposed by chemistry [Martin,BR]
Eletrons don't literally 'spin', because they are point-like [Martin,BR]
The Exclusion Principle says no two fermions occupy the same state, with the same numbers [Martin,BR]
The properties of a particle are determined by its quantum numbers and its mass [Martin,BR]
Virtual particles surround any charged particle [Martin,BR]
Electron emit and reabsorb photons, which create and reabsorb virtual electrons and positrons [Martin,BR]
If an expected reaction does not occur, that implies a conservation law [Martin,BR]
The Higgs field, unlike others, has a nozero value in a state without particles [Martin,BR]
String theory only has one free parameter (tension) - unlike the standard model with 19 [Martin,BR]
