The aim of the following pages is to provide some means for students to improve their knowledge of particle physics by playing with some real data recently collected in the ALEPH experiment. To make it possible we provide some description of the experiment, of its detector and of some physics topics which are simple enough to be presented here.
A similar teaching project exists in
german, developed
by Sascha Schmeling
Look at an electron-positron
collision seen along the beam axis.
The positrons enter into the plane
of the diagram and the electrons leave the plane.
The electrons and positrons collide at the
interaction point at the center of the detector.
The center of the LEP ring is toward the right side of the diagram.
Before having a look at physics it may be good to learn about the ALEPH Detector. You will then be able to understand the way the particles interact with the different elements of the detector, leaving a trace of their nature.
In the following pages we will try to give you the possibility to learn some particle physics from looking at and histograming ALEPH events.
Learning about quarks from a
nice event.
Learning about
Z decays into leptons.
