Facts about
mesons
1. Charge mesons decay to form electrons
and neutrinos
2. Mesons are hadrons
3. Mesons are composite particle with
one quark and one antiquark.
4. Mesons and baryons are the two
families of particles containing quarks.
5. Mesons are held by a strong nuclear
interaction.
6. It was discovered by sir Hikedi Yukawa
7. All mesons are unstable particles.
8. Uncharged mesons decay into protons.
9. Mesons can have positive, negative or
neutral electrical charge.
10.
Mesons
are not radioactive products.
11.
Mesons
are produced from high energy collision like in cosmic rays.
12.
Mesons
are intermediate particles of nucleus.
13.
They
can best be describes as particle composing of two quarks.
14.
Mesons
are bosonic.
15.
Mesons
are fermions.
16.
They
are not subjected to Pauli Exclusion principles.
17.
Antiparticles
of meson are called antimesons.
18.
All
types of mesons have their corresponding antiparticles
19.
Pion
is a meson
20.
Kaon
is a meson
21.
+pion
is made up of up quark and down antiquark.
22.
–pion
is made up of up antiquark and down quark.
23.
–pion
is an anti particle of positive pion.
24.
Mesons
with no orbital momentum have odd parity.
25.
Mesons
are affected by both strong and weak nuclear interactions.
26.
They
are lighter than baryon.
27.
Lighter
ones are less unstable than heavier ones.
28.
Nuclear
force is what keeps more than a proton in a nucleus.
29.
Muon
is the first mesons discovered.
30.
Muon
was discovered by Sir Carl David.
31.
Mesons
intrinsic parity is the product of intrinsic parities of constituent quarks and
antiquarks.
32.
Mesons
have diameter of about 10-15m.
33.
Life
time of mesons ranges from 10-18 to 10-22 seconds.
