Fundamental interactions and particles


  • Orimar Antônio Battistel Departamento de Física, Centro de Ciências Naturais e Exatas - CCNE Universidade Federal de Santa Maria - UFSM, Santa Maria, RS.



We present a discussion of some of the ideas and facts that led to the modern conception of the structure of matter in terms of basic constituents and fundamental interactions. We discuss the construction of the quark model in a historical context, stressing that the phenomenological knowledge of particle properties induced the mathematical formalism. The interaction between quarks is discussed in the framework of the color force based on the exchange of gluons. For the sake of completeness we mention briefly the microworld structure that emerged from these new ideas.
