How are elementary particles detected?

Answer 1

By collisions.

Incoming particles are inserted into an accelerator and sent to collide; out of that collision, new particles emerge and are set to collide again, but this time with a detector, which is essentially a calorimeter designed to stop the particle entirely. From the amount of heat one obtains the mass of the particle. The only way to find a particle is to observe it in its interaction with others.

Positive charges rotate in the opposite direction as negative charges when placed in a magnetic field; electric charge is found by following the path of the particle inside the detector.

Elementary particles are detected through various methods, including particle accelerators, detectors, and indirect observation techniques such as studying their interactions with matter or electromagnetic fields.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
