... The weak force can be seen in the decay of the neutron. If a neutron is just sitting around, after ten or fifteen minutes it will decay into a proton, an electron, and another elementary particle (the electron anti-neutrino, to be precise). This could not be explained by the other forces, leading to ...

Nonuniform and constant magnetic field
... We start from the Lorentz equation without electric field, F~ = q~v × B. If we average on the gyroperiods, the x average component is zero, Fx = 0. For the y component, we have Fy = −qvx Bz (y). using the results of the previous notebook for vx and ...

When the K, Λ, and Σ particles were first discovered in the early 1950s, there were mysteries associated with them: • They are always produced in pairs. • They are created in a strong interaction, decay to strongly interacting particles, but have lifetimes characteristic of the weak interaction. To ...

Problem Set 2
... If you walk across a nylon rug and then touch a large metal object such as a doorknob, you may get a spark and a shock. Why does this tend to happen more on dry days than on humid days? (Hint: a water molecule is an example of an electric dipole.) Why are you less likely to get a shock if you touch ...

Effects of scattering centers on the energy spectrum of a quantum dot

In Fig. 1~a! these two states are degenerate at B50 T with energy eigenvalue about 8.6 meV. In Fig. 1~b! this degeneracy is clearly lifted due to the broken circular symmetry. Anot ...
