![]() The nuclear fusion inside the sun, nuclear fission inside atomic reactors and cosmic ray collisions with atoms are some of the reasons for the creation of these particles. They are created due to certain types of nuclear decays or nuclear reactions. This small amount of mass and the electrical neutrality are the reasons the neutrino has very little or almost no interactions with matter. The mass of this particle is very small but not zero. The neutrino is an elementary subatomic particle, which has very weak interactions with matter which means, it can pass through matter without making many interactions such as collisions and diversions. We can denote it by the Greek letter ν (nu). This means antineutrino is an elementary particle of half-integer spin (spin 1 ⁄ 2 ) that does not undergo strong interactions. Therefore, the detection of antineutrons is hard. Also, antineutrinos interact through weak forces and gravitational forces only. Like the neutrino, antineutron also has a spin of ½. Particle-antiparticle pairs having this property (a particle having its own antiparticle with same properties) are known as Majorana particles. Since neutrino has no charge, some people propose that neutrino and antineutrino are the same particles. Moreover, an antineutrino is the antiparticle of the neutrino. For the annihilation to occur, both the particle and the antiparticle must exist in the appropriate quantum states.įigure 01: Formation of an Antineutrino from Beta Decay If a particle and an antiparticle contacts, they will annihilate to produce energy. However, the charge is not the only difference between particles and antiparticles. An antiparticle is a particle having the same mass, but the opposite charge to a certain particle. ![]() Most of the particles we know have antiparticles. To understand what an antineutrino is, one must first understand what antiparticles are. Side by Side Comparison – Antineutrino vs Neutrino in Tabular Form On the other hand, an antineutrino is the anti-particle of neutrino. We show that the quantum field theoretical framework, where flavor vacuum is defined, permits giving a precise definition of flavor states as eigenstates of (non-conserved) lepton charges. We can define a neutrino as a subatomic particle having no electrical charge (but other properties are similar to an electron), very little mass and it is very abundant in universe. We review some of the main results of the quantum field theoretical approach to neutrino mixing and oscillations. We can use the properties such as mass, charge, and spin of these particles in many ways to detect and determine properties of systems. There are many usages of neutrino and antineutrino in various fields. The key difference between antineutrino and neutrino is that the neutrino is a particle whereas the antineutrino is an antiparticle. Neutrino and antineutrino are two subatomic particles.
