40 Facts About Leptons as One of Fundamental Particles

Fact about leptons

1.     Leptons are fundamental particle outside the nucleus of an atom

2.     Leptons are not affected by strong nuclear force.

3.     Examples of lepton are electron, muon and tau etc

4.     Leptons are not composite or divisible and therefore are fundamental particle.

5.     Electrons, electron neutrinos, muon , muon neutrinos, tau and tau neutrinos are the six types of leptons.

6.     Leptons have three generations viz, 1^st, 2^nd and 3^rd generations.

7.     Hadrons are affected by strong force while leptons are independent of this force.

8.     Leptons are represented by l.

9.     The anti particle of lepton is called antilepton.

10.                        Unlike hadrons leptons do not have a color charge.

11.                        Electron is a lepton.

12.                        Electron is the least mass of all types of lepton and therefore the lightest.

13.                        Muon and tau decay into electron in a process called particle decay.

14.                        Electron is the only stable lepton the rest undergo particle decay.

15.                        Leptons are subjected to electromagnetic force.

16.                        They are subjected to gravitational force ( gravity).

17.                        They are subjected to weak nuclear force called weak interaction.

18.                        All leptons have antiparticles.

19.                        1^st generation leptons are electron an electron neutrinos.

20.                        2^nd  generation are muon and muon neutrino.

21.                        3^rd generation lepton is tau and tau neutrinos.

22.                        Electron is discovered in 1897 by J.J thompson.

23.                        Lepton was classified as  fundamental particle in 1947.

24.                        Lepton is subjected to pauli exclusion principles.

25.                        Lepton is fermionic.

26.                        Electron is a charged leptons.

27.                        Neutrinos are neutral leptons.

28.                        Has a spin of -½

29.                        Charged leptons can combine with hadrons to form an atom.

30.                        Neutral leptons do not combine with other particles.

31.                        Lepton is affected to all fundamental forces except strong interaction.

32.                        Particle decay is the transformation from higher mass state to a lower mass state.

33.                        Electrons are stable and common in the universe while muon and tau are not common.

34.                        Muons are produced in the decay of pions in the upper atmosphere.

35.                        Muons have a lifetime of 2.20 microseconds.

36.                        Tau is the most massive lepton.

37.                        Tau is about 3470 time heavier than electron.

38.                        Muon is 200 times more massive than electrons.

39.                        Leptons and anti leptons have same masses but opposite properties.

40.                        Leptons can exist independently while quarks cannot exist independently.
