Quarks

Question 1

What are quarks?

Answer 1

The building blocks for Hadrons.

Question 2

what are anti-particles of Hadrons made from?

Answer 2

Anti quarks

Question 3

What are Mesons?

Answer 3

Hadrons

Question 4

What are baryons and anti-baryons in terms of quarks?

Answer 4

Baryons and anti-baryons are Hadrons that consist of three quarks for a baryon or three anti-quarks for an anti-baryon.

Question 5

What quarks are involved in strange particles?

Answer 5

Strange Quarks, S

Question 6

What does it mean for strangeness to be a quantum number?

Answer 6

It can only take a certain set of values, it therefore has to be conserved.

Question 7

What interaction is strangeness conserved in?

Answer 7

Strong interactions

Question 8

What interaction breaks down strangeness?

Answer 8

Weak Interaction

Question 9

How is strangeness conserved?

Answer 9

• Strange particles are always produced in pairs.
• One particle has a strangeness of +1
• Other particle has a strangeness of -1

Question 10

How many quarks are mesons made from?

Answer 10

2

Question 11

How many quarks are baryons made from?

Answer 11

3

Question 12

What is the anti particle of a pion?

Answer 12

Uncharged pion’s antiparticle is itself.

Question 13

What is quark confinement?

Answer 13

• It is impossible to get a quark on its own.

Blasting a proton with energy will get changed in quarks and anti-quarks, producing mesons.
