What is the Neutrino Observatory Project?

Published: December 6, 2019

A neutrino is an electrically neutral fermion. Fermion is a particle that follows Fermi-Dirac statistics, which describes a distribution of particles over energy states in systems that consists of identical or similar particles that obey the Pauli exclusion principle. In December 2017, the Union Cabinet committee on security approved the India based Neutrino Observatory Project. ..

Applications of Neutrinos

Published: May 21, 2018

The neutrino is a tiny elementary particle, but it is not part of the atom. They exist in nature. Neutrino has a very tiny mass, no charge and spins half. It interacts very weakly with other matter particles so weakly that every second trillions of neutrinos fall on us and pass through our bodies unnoticed. ..

Baryons and Omega C-0 Particles

Published: May 19, 2018

In March 2017, five new sub-atomic particles were discovered by Large Hadron Collider scientists at CERN. These particles have been collectively called Omega C0 and have been named Oc(3000)0, Oc(3050)0, Oc(3066)0, Oc(3090)0 b Oc(3119)0 as per their masses megaelectronvolts (MeV). Omega-c-zero is a baryon. It is a particle with three quarks, containing two strange and ..

Neutrinos and Neutrino Oscillation

Published: May 1, 2018

Neutrinos are one of the elementary particles, which make up the universe. They are similar to electrons except that they do not carry electric charge. As they are electrically neutral, they are not affected by the electromagnetic forces like electrons or protons. Neutrinos are only leptons with no electric nature. Other leptons, which carry electric ..
