In part 4 events of the types you met in Parts 2 and 3 will
be mixed up together. So, first you have to decide whether the event you're
looking at is the type in which a matter particle-antiparticle pair has been
produced (like Part 2) or it is the type of event in which a W+W-
pair has been produced (like Part 3). After you've done that, then see if you
can identify exactly which sort of event you're looking at. Note down your
answers and reasoning and discuss it with your partner to see if you can reach
a consensus. DO NOT discuss with or copy answers
from other pairs – this will be deemed plagiarism and you will be failed
in the course!
