The Particle Adventure
A mirror site is
Take the interactive tour of quarks, neutrinos, antimatter, extra dimensions
dark matter, accelerators and particle detectors! Tour each section, and
then answer the questions below! Have fun!
|What is Fundamental?
- In order for a particle to be considered
what must be true about it?
- Are quarks considered to be fundamental?
- What is the maximum size (in meters) of
electrons and quarks?
- According to the Standard Model, what
accounts for all of the
subatomic particles and the interactions between them?
|What is the World Made of?
- In what way is a particle different from
- What is the unusual characteristic of
- How are the generations of matter
- Which generation(s) of matter is the
in the universe made of?
- Why arenít other particles included in
|What Holds it Together?
- Whatís the difference between a force and
- What is a force at the fundamental level?
- What does the residual E-M force allow
atoms to do?
- What two types of charge do quarks
- What does the residual strong force do
thatís so important?
- What are weak interactions responsible
|Particle Decays and
- What does particle decay refer to when we
about fundamental particles?
- Give examples of decays caused by the
and weak interactions!
- At approximately what particle energies do
some GUTs predict
that the strong, electromagnetic and weak forces merge?
- What is supersymmetry?
|How do we know any of this?
- How do we improve the resolution of our
|How Do We Experiment With Tiny
- What is used to accelerate particles in an
- What is the advantage the colliding-beam
- What types of particles are detected in
the tracking chamber?
- What does the hadron calorimeter measure?
- Why are muons and neutrinos the only
particles detected in the
- How is the presence of neutrinos inferred
from muon chamber data?
|How Do We Interpret Our Data?
- Why arenít neutrons and photons detected
in the tracking chamber?
- How do researchers know that a particle
detected in the muon chamber
is actually a muon and not some other particle?
