... When charged particles pass through matter, they ionize atoms in their path, liberating charges, and causing the emission of detectable light (scintillators) or the formation of tracks of droplets (cloud/bubble chambers). This is how we “see” them. Experimental physicists use many kinds of particle ...

... Thompson put gas into a glass tube at a near-vacuum and put a charge through it, causing a beam of light. When an electromagnet was placed near the tube, the beam was deflected away from the negative and towards the positive. The results were the same for all gases he used, thus he proved that since ...

Essentials of Particle Physics
... •Just as the equation x2=4 can have two possible solutions (x=2 OR x=-2), so Dirac's equation could have two solutions, one for an electron with positive energy, and one for an electron with negative energy. •Dirac interpreted this to mean that for every particle that exists there is a corresponding ...

What does LHC stand for
... Why does matter have mass? Can we find the Higgs boson, the particle which will explain mass? Matter and antimatter must have been produced in the same amounts at the time of the Big Bang, but from what we have observed so far, our Universe is made only of matter. Why? The LHC could help to provide ...

... A simple assumption for the proton model is that it is a composite sphere containing three fundamental point-like components. We assume that these three components are pointlike electrons. If two of these have positive charge and one has negative charge, it is a natural consequence of this model tha ...

Assignment for Physics 295 – Professor Thomson – due May 2 2005
... energies are typically not well-measured by particle detectors, an assumption that two of the jets come from a W boson decay can actually reduce the uncertainty on the jet energies and thus on the top quark mass. The world’s best measurement from CDF goes a step further and uses the hadronic W decay ...
