How Do We Interpret Our Data? Typical Detector Components The reason that detectors are divided into many components is that each component tests for a special set of particle properties. These components are stacked so that all particles will go through the different layers sequentially. A particle will not be evident until it either interacts with the detector in a measurable fashion, or decays into detectable particles.
The interaction of various particles with the different components of a detector:
*Neutrinos are not shown on this chart because they
rarely interact with matter,
and can only be detected by missing matter and energy.
Just so you know, the pion

A few important things to note:
![]() An electron and a positron were produced when a particle and its antiparticle collided head-on, perpendicular to this screen. What conservation law APPEARS to have been broken?
![]()
Charge?
The conservation of momentum appears to be violated, but there were unseen neutrinos. |
