Answer to Problem 38P

Solution:

  1. udd
  2. udd¯
  3. uds
  4. uds

Explanation of Solution

  1. The charge of the neutron is 0. Thus, the quark combination for neutron should also have charge 0. The quark up(u) and down(d) have charge 23 and 13 .
  2.   Physics: Principles with Applications, Chapter 32, Problem 38P , additional homework tip  1

    The quark combination ofthe neutron is udd.

  3. Antineutron is antiparticle of neutron. Thus, it is reversal of neutron. Antiparticle of u is u¯ and d is d¯ .
  4.   Physics: Principles with Applications, Chapter 32, Problem 38P , additional homework tip  2

    The quark combination of neutron is udd¯ .

  5. The charge of Σ0 is 0. Thus, the quark combination for Σ0 should also have charge 0. The quark up(u), down(d) and strange(s) have charge 23 , 13 and 13 .
  6.   Physics: Principles with Applications, Chapter 32, Problem 38P , additional homework tip  3

    The quark combination of Σ0 is uds.

  7. c) and d) are the same.

Conclusion

  1. The quark combination ofthe neutron is udd.
  2. The quark combination ofantineutron is udd¯ .
  3. The quark combination of Σ0 is uds.
  4. The quark combination of Σ0 is uds.
