Hadrons

• What are hadrons made up of?

  Quarks

  
• What force can hadrons feel?

  Strong nuclear force
• What are the two classes of hadrons?

  • Baryons (3 quarks)
  • Mesons (quark and anti-quark pair)

  
• What are the most common baryons?

  Protons and neutrons

  
• What are the most common mesons?

  Pions and kaons
• Can hadrons be classified as baryons or mesons?

  Yes, hadrons can be either

  
• What are the two classes of anti-hadrons?

  • Anti-baryons (3 anti-quarks)
  • Anti-mesons (quark and anti-quark pair)

  
• What is the composition of anti-baryons?

  Three anti-quarks
• What is the composition of anti-mesons?

  Quark and anti-quark pair
• Have quarks ever been discovered alone?

  No, always in pairs or groups
• What type of charges do baryons and mesons have?

  Integer (whole number) charges
• What is the charge composition of quarks in a baryon?

  All quarks or all anti-quarks

  
• What happens to the quark in a meson when it becomes an anti-particle?

  It becomes the anti-quark
• What are hadrons?

  Subatomic particles made up of quarks

  
• Why can hadrons feel the strong nuclear force?

  Because they are made up of quarks

  
• What are the two classes of hadrons?

  Baryons and mesons

  
• What are baryons?

  Hadrons made up of 3 quarks

  
• What are mesons?

  Hadrons made up of a quark and anti-quark pair

  
• What are the most common baryons?

  Protons and neutrons

  
• What are the most common mesons?

  Pions and kaons
• What are the two classes of anti-hadrons?

  Anti-baryons and anti-mesons

  
• What is the difference between an anti-baryon and an anti-meson?

  Anti-baryons are made of 3 anti-quarks, while anti-mesons are made of a quark and anti-quark pair

  
• Why have quarks never been discovered on their own?

  Quarks are always found in pairs or groups of three
• What is the charge of hadrons?

  Hadrons have integer (whole number) charges

• What are the key differences between baryons and mesons?

  • Baryons are made up of 3 quarks, while mesons are made up of a quark-antiquark pair
  • Baryons have integer charges, while mesons can have fractional charges
  • The most common baryons are protons and neutrons, while the most common mesons are pions and kaons

  
• What are the key differences between hadrons and anti-hadrons?

  • Hadrons are made up of quarks, while anti-hadrons are made up of anti-quarks
  • There are two types of hadrons: baryons (3 quarks) and mesons (quark-antiquark pair)
  • There are two types of anti-hadrons: anti-baryons (3 anti-quarks) and anti-mesons (quark-antiquark pair)
