Описание: In particle physics and quantum field theory we are usually dealing with particles that are moving fast and are very small, i.e. the particles are both relativistic and quantum mechanical and therefore our formulas have lots of factors of с (speed of light) and h (Planck's constant). The formulas considerably simplify if we choose a set of units, called natural units where с and h are set equal to 1. In CGS units (often also called Gaussian [Jackson appendix] units), the basic quantities of length, mass and time are centimeters {cm), gram (g), seconds (sec), or in MKSunits these are meters (m), kilogram (kg), seconds. In natural units the units of length, mass and time are all expressed in GeV.
