Question 1

Particles can decay to only lighter states. T or F?

Answer 1

True

Question 2

What units does the decay width have?

Answer 2

Energy

Question 3

What is the flux?

Answer 3

number of particles crossing an area per unit time

Question 4

Only positive energy solutions are possible. T or F?

Answer 4

False. relativistic energy momentum equation is quadratic, so negative solutions are possible.
