These lecture notes form the introduction to the CERN course. They cover the ba-sics of particle physics and are designed to be accessible to students with any scientific background. This means that, despite the advanced topics, the notes require signif-icantly less mathematical sophistication than my other lecture notes. Sadly there is
The Standard Model of particle physics is the mathematical theory that describes the weak, electromagnetic and strong interactions between leptons and quarks, the basic particles of the Standard Model.
“Pre-particle physics” A simplistic view on matter at 1900: Indivisible atoms form the matter molecules around us, combining only in certain proportions (Richter and Dalton). Avogadro’s law: At fixed temperature and pressure, equal volumes of gas contain equal numbers of molecules. Atomic weights are (roughly) integer multiples of the ...
For a very elementary introduction to the Standard Model, you could take a look at the lectures on Particle Physics that I wrote for the CERN summer school. They cover the subject in a great deal of detail, but without any real mathematical sophistication.
In the Standard Model, all matter is made of spin 1 2 fundamental particles. There are two types, each with 3 generations: Consequence of relativity and quantum mechanics (Dirac equation) Antiparticle for every existing particle: identical mass, spin, energy, momentum, but has the opposite sign of interaction (e.g. electric charge).
Most alpha particles passed straight through the foil with no deflection - this suggested that the atom is mostly empty space (and did not have a uniform density, as suggested by the plum pudding model).
