SUMMARY

The discussion centers on the detection of particles with a length scale of 10^-21 meters, which corresponds to energies around 200 TeV, as derived from the equation \hbar c = 200 MeV fm. Participants note that no current particle accelerator can achieve such high energies, raising questions about the assignment's validity. The context indicates that this is part of a course in experimental physics, where students are tasked with describing detection methods for extremely small scales.

PREREQUISITES
  • Understanding of quantum mechanics and particle physics
  • Familiarity with energy-mass equivalence and the relationship between length and energy
  • Knowledge of current particle accelerator capabilities
  • Basic principles of experimental physics and detection methods
NEXT STEPS
  • Research the capabilities of current particle accelerators, focusing on the Large Hadron Collider (LHC)
  • Study the principles of quantum field theory and its implications for particle detection
  • Explore experimental techniques for measuring subatomic particles
  • Investigate theoretical frameworks for energies exceeding 200 TeV
USEFUL FOR

Students in experimental physics, particle physicists, and researchers interested in high-energy physics and advanced detection methods.

Hi, does anyone know of something of length of order 10^-21 m? I need it for an assignment to describe the detection of something of that length

Regards

Look : [tex]\hbar c[/tex] = 200 MeV fm

so, [tex]10^{-21}[/tex] m naturally correspond to energies of order 200 TeV !

Dude, that's a lot ! No current accelerator is able to reach this energy.

Are you certain of the value you are quoting here ?
Could it be the teacher is trying to trick you ?
 
Yeh its definitely that small, its this stupid unit called methods of experimental physics, we all got assigned a power of 10 and told to describe the operation of a detector to measure a length of that magnitude...i fail to see any point in this but its got to be done
