Ensiöhiukkaset

Ensiöhiukkaset, also known as primary particles, are the fundamental building blocks of matter that are not produced by the decay or interaction of other particles. In the realm of particle physics, these are the elementary particles like quarks, leptons (such as electrons and neutrinos), and force carriers (like photons and gluons). They are considered indivisible within the current understanding of physics.

These elementary particles are theorized to be point-like and possess intrinsic properties like mass, charge, and spin. They are not composed of smaller constituents. The Standard Model of particle physics classifies these fundamental particles into two main categories: fermions, which make up matter, and bosons, which mediate forces.

In contrast, secondary particles are those that are produced when primary particles collide at high energies, such as in particle accelerators or cosmic ray interactions. For example, when a proton collides with another proton, numerous other particles, including mesons and other baryons, can be created from the energy of the collision. These are considered secondary as they are a result of the interaction of the initial ensiöhiukkaset. The study of ensiöhiukkaset and their interactions is central to understanding the fundamental laws of the universe.
