Which of the following is not a quantum number associated with elementary particles and their interactions?
  a. strangeness
  b. hypercharge
  c. isospin
  d. baryon number
  e. gluon number

Question 2

Examine the muon decay by weak interaction and choose the correct statement about the lepton conservation numbers Le, L, and L .
 
 
a. L = Le = L = 0 for both sides of the equation
  b. L = -1, Le = -1, L = 0 for both sides of the equation
  c. L = 1 for the left side, Le = 1 for the right side, and L = 0 for both sides of the equation
  d. L = -1, Le = 0, L = 0 for both sides of the equation
  e. L = 0, Le = -1, L = 0 for both sides of the equation


Question 3

A neutron can be described as all of the following except:
 
a. hadron
  b. baryon

Answer to Question 1

e.
There is no quantum number governing the behavior of the gluon because the gluon is a gauge boson, or force carrier.

Answer to Question 2

The lepton number for each of the families , electron, and must be conserved in any reaction. Accordingly, the number must be the same on either side of this equation. In this case, an anti-muon and anti-muon neutrino are both -1, and both of the electron family cancel each other on the right side of the equation. The tau number is zero for both sides.
d.

Answer to Question 3

e.
