Bosons and Fermions: - BOSONS Introduction: In particle physics boson is the type of particle that obeys the rule of Bose- Einstein statistics. CONTENTS Preface vii Introduction 1 Elementary Particle Physics 1 How Do You Produce Elementary Particles? It’s analogous to the arrangement of atoms based on different characteristics in the periodic table. Baryons are the heaviest particles of all, followed by mesons. Historically, elementary particles were such objects that have no known internal structure that is, colloquially speaking they are indivisible. Every inch of this visualization is active. 4 How Do You Detect Elementary Particles? 7 Units 8 References and Notes Thus, they ceased to be elementary in a literal sense. Hadrons are subject to the strong nuclear force, they are not fundamental particles as they are made up of quarks. ), so we call an electron fundamental because they are all non-unique. Classification of Elementary Particles Elementary particles are categorized on the basis of their nature and properties. Fundamental particles called quarks come in six different flavors. Protons are made of two up quarks and one down quark, while neutrons contain two down quarks and one up quark. Where do these 31 elementary particles come from? Nobody knows. Move your mouse over a category to show which particles belong to that category. Classification of the Elementary Particles. Why these 31, rather than some other 31? All electrons have the exact same characteristics (mass, charge, etc. On the basis of mass, elementary particles are divided into four types: Massless particles Light particles Intermediate particles Why 31? The particle page explores the history of the discovery of tiny particles from the atom to the quark. In contradiction to this very basic principle of contemporary physics, this article proposes a new concept that particles in the gravitation field The Standard Model (formulated in 1970) organized elementary particles into different well-defined groups, based on particle interactions and other measurable properties. The search for the origin of matter means the understanding of elementary particles. They are classified on the basis of mass, charge, average lifetime, spin, interaction etc. These are, referring to their masses: (1) the photon with zero rest mass and spin 1. Classification of Elementary Particles Elementary particles can be classified on the basis of different properties of particles. This group is then spilt up into baryons and mesons. Leptons are the lightest particles. Hadrons. Hadrons are the heaviest particles. It is a massless boson. Many of the particles we have discussed so far appear simple in their properties. (2) the leptons or light particles. In contemporary physics elementary particles are classified by energy, live time and other properties. With the development of science, particles that were formerly considered indivisible turned out to be assembled from two or more other, smaller particles. CLASSIFICATION OF ELEMENTARY PARTICLES #Classification On the basis of “SPIN”: - •Elementary Particles are categorised in two classes i.e. Quantum mechanics changed our perception of elementary particles from strictly point objects to dual function objects encompassing both wave-like and point-like properties. Move your mouse over a particle to show its name, classification, properties and further information. Elementary particles are classified into groups according to their mass and spin properties.
