Belle II  IMC Masterclasses 2021 dates for different timezones, Register now!

Welcome to the home of the Belle II masterclass. During the adventure  you will be able to play with the data acquired with a big particle detector. Millions of particles are waiting for you to combine them and find their mother particles. These are well hidden. Your help is needed!

The Belle II measurement adventure includes:

  • Visualization of Events – Display of the collision events in the Belle II spectrometer.
  • Introduction to the invariant mass –  combining the masses and momenta of two selected particles
  • Discovery of new particles – students describe a two body decay and search for new particles on the sample of about 5 mio. of events from Belle and Belle II experiments.
  • Fitting and determining the mass and yields of the discovered particle. 

Supporting material:

Belle II spectrometer

Belle II detector is a huge magnet, instrumented with diferent sensors used for tracking and identification of decay products formed during collision of positrons and electrons.

About

The Belle II collaboration consist of over 984 physicist and engineers from 115 institutions in 26 countries. Visi our homepage for more info
