Coupling Physics and Geometrica -- from Wolfram Library Archive (264 words) |
 | The specification of the magnetic field and of the length of a dipole determine the angle of rotation of the beam at given particle momentum. |
 | The physics part of the program consists basically in the determination of the particle orbits and of the beam shape. |
 | The geometry part uses the basic parameters and the physics results to generate exactly the layout of an accelerator and, in first approximation, the shape of its elements. |

Coupling Constants for the Fundamental Forces (595 words) |
 | In obtaining a coupling constant for the strong interaction, say in comparison to the electromagnetic force, it must be recognized that they are very different in nature. |
 | This coupling constant is also called the "fine structure constant" since it shows up in the description of the fine structure of atomic spectra. |
 | The lifetime of a particle is proportional to the inverse square of the coupling constant of the force which causes the decay. |
