Peruspartikkelista

Peruspartikkelista is a term used in some theoretical physics contexts, particularly in Finnish scientific literature, to describe a fundamental particle. It is not a standard term in mainstream English-language physics, where "elementary particle" or "fundamental particle" are commonly used. Fundamental particles are considered to be indivisible constituents of matter that are not composed of smaller particles.

The Standard Model of particle physics categorizes fundamental particles into two main groups: quarks and leptons. Quarks are the building blocks of composite particles like protons and neutrons, while leptons include electrons and neutrinos. Both quarks and leptons are classified as fermions, meaning they have half-integer spin. Additionally, the Standard Model includes bosons, which are force-carrying particles such as photons (electromagnetism) and gluons (strong nuclear force), as well as the Higgs boson, responsible for giving mass to other particles.

The concept of peruspartikkelista, like its English counterparts, stems from the ongoing quest to understand the most basic components of the universe and the forces that govern their interactions. While the Standard Model is highly successful, physicists continue to explore theories beyond it, such as supersymmetry, which propose the existence of additional fundamental particles. The investigation into peruspartikkelista or elementary particles remains a central theme in modern physics research.
