A neutrino is?

Answer 1

A practically mass-less particle given off during the process of nuclear fusion or fission. They are charge-less and therefore interact with almost nothing. They were predicted to exist as a way to balance nuclear reaction equations and were subsequently proven to exist (along with there counterparts the anti-neutrino).

Answer 2

A few facts on neutrinos:

Neutrinos are one of the fundamental particles in the universe.

The name neutrino was coined by Enrico Fermi - who developed the first theory describing neutrino interactions - as a word play on neutrone, the Italian name of the neutron. (Neutrone in Italian means big and neutral, and neutrino means small and neutral.).

Neutrinos do not carry an electric charge, unlike electrons. Neutrinos interact with a "weak" sub-atomic force (different from electromagnetism), and can pass through matter without being affected by it. There are three different types of neutrinos: nu_e, nu_mu, nu_tau.

There are many resources on neutrinos on the web. See the source list below.

Answer 3

According to Malaku and Lah (c. 2029), a neutrino is a particle in 7 out of the 10+1 spatial dimensions. It has 2 out of the necessary 4 vectors for "classic existence" (also currently referred to as 1/2 particle spin). Pioneered by K. Chatterjee in 2018, it was the use of highly focused neutrino "beams" for the purpose of "negative relief" microscopy in the Hudson lab at MIT that allowed science to gain a better understanding of the hyperdimensional quality of fermions and leptons, which led to the final mathematical union of quantum and classical mechanics in early 21st century and the eventual creation of the Kamalesh gate.

Answer 4

A neutrino is an elementary particle of the leptons.
It can penetrate any atom easily.
There is a big chanche that it can move through the earth completely without any collision.

For all six kinds of neutrino's you can say:
--- Its mass is much smaller than the mass of an elctron.
--- It has no electric charge.
--- It has elemenary spin.

Answer 5

The neutrino is an elementary particle. It has half-integer spin and is therefore a fermion.

Answer 6

Cosmic Gall
NEUTRINOS, they are very small.
They have no charge and have no mass
And do not interact at all.
The earth is just a silly ball
To them, through which they simply pass,
Like dustmaids down a drafty hall
Or photons through a sheet of glass.
They snub the most exquisite gas,
Ignore the most substantial wall,
Cold shoulder steel and sounding brass,
Insult the stallion in his stall,
And scorning barriers of class,
Infiltrate you and me! Like tall
and painless guillotines, they fall
Down through our heads into the grass.
At night, they enter at Nepal
and pierce the lover and his lass
From underneath the bed-you call
It wonderful; I call it crass.

Answer 8

a fundamental particle with no charge and near massless( practically no mass).

Answer 9

particle with half-spin ie its an fermion.Generally have left handed chirality.Considered to be massless.

Answer 10

really really really really really small.
