Why baryons have spin and mesons have spin .
Answer to Problem 14Q
Solution:
Baryons have spin and mesons have spin .
Explanation of Solution
Baryons consists of three quarks or antiquarks. The spin of each quark is and the spin of anti-quark is .
The possible spin configurations for baryons is,
• The spin of two quarks and one antiquark is
• The spin of one quark and two anti-quarks is .
• The spin of three quarks is .
• The spin of three anti-quarks is .
Mesons consists of two quarks or two anti-quarks. The spin of each quark is and the spin of anti-quark is .
The possible spin configurations for mesons is,
• The spin of two quarks is 1.
• The spin of two anti-quarks is -1.
• The spin of one quark and one anti-quark is 0.
