Rules of the Game• 10 multiple-choice questions + 1 “tie-breaker”
• ~30 seconds per question• Work in groups of 2
• Answer sheets • 2 sections• fill in both• hand bottom part to your instructor
• Winning teams in each institute will receive a prize from CERN
• Overall winning team of the day will receive an additional prize from CERN
• But the main aim is to have fun!

Question 1
Our detector shows a signal only in the hadronic calorimeter (no signal in the tracker, electromagnetic calorimeter or muon chambers). Therefore, this signal is most likely
Náš detektor ukazuje signál len v hadrónovom kalorimetri (žiaden signál v dráhovom detektore, elektromagn. kalorimetri, ani v miónových detektoroch). Preto tento signál s najväčšou pravdepodobnosťou pochádza od
A. a NEUTRONB. a PIONC. an ELECTROND. a PHOTON
