About Ghost Particles:

Neutrinos are tiny subatomic particles, often called ‘ghost particles’ because they barely interact with anything else.
Source: Neutrinos come from all kinds of different sources and are often the product of heavy particles turning into lighter ones, a process called “decay.”
Neutrinos are denoted by the Greek symbol ν, or nu (pronounced “new”).
They belong to the family of particles known as leptons. There are three main leptons, namely electrons, muons and tau particles, and each one has an associated neutrino and anti-neutrino.
A neutrino is very similar to an electron, but has no electrical charge and a very small mass.
They are the most common particle in the universe. Approximately 100 trillion neutrinos pass completely harmlessly through our body every second.
They are extraordinarily difficult to detect, as they rarely collide with atoms.
Of the four fundamental forces in the universe, neutrinos only interact with two — gravity and the weak force.
But not all neutrinos are the same. They come in different types and can be thought of in terms of flavors, masses, and energies.

What is Antiparticle?

In quantum theory, every type of particle is associated with an antiparticle with the same mass but with opposite physical charges. For example, the antiparticle of the electron is the positron.

Q1) What is Antiparticle?

In quantum theory, every type of particle is associated with an antiparticle with the same mass but with opposite physical charges. For example, the antiparticle of the electron is the positron.
