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

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.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
