1. What is the direction of the magnetic field if the incoming beam is of K-particles?
A 2. How many charged particles leave point A ? 2
A 3. Is the event at point A, a decay or a collision ? a collision
B 4. What can we say about the particle that produces the event at point B; what is it’s charge? It is a neutral particle
B 5. The particles leaving the decay point B are pions p . What are their charges? p+ p-
E 6. Connect point D with E Does the neutral particle that decays at point D come from point C or A ? D C A From the kink at point C For justification of method, click here: http://teachers.web.cern.ch/teachers/archiv/HST2005/bubble_chambers/BCwebsite/articles/V0_decays.pdf
E 7. Which of the particles that travel between points D and E has the larger momentum? D The positive particle
8. What particle travels between points A and C? W -, K -, S+ or X - ? C A W- http://teachers.web.cern.ch/teachers/archiv/HST2005/bubble_chambers/BCwebsite/index.htm
