Flashcards in Quarks Deck (13):
1

What are quarks?

The building blocks for Hadrons.

2

what are anti-particles of Hadrons made from?

Anti quarks

3

What are Mesons?

Hadrons

4

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

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

5

What quarks are involved in strange particles?

Strange Quarks, S

6

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

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

7

What interaction is strangeness conserved in?

Strong interactions

8

What interaction breaks down strangeness?

Weak Interaction

9

How is strangeness conserved?

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

10

How many quarks are mesons made from?

2

11

How many quarks are baryons made from?

3

12

What is the anti particle of a pion?

Uncharged pion's antiparticle is itself.

13

What is quark confinement?

• 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.
