２２　Weinberg-Salam theory【What is the Universe？】Dialogue with the Universe

○In Weinberg-Salam theory(1967), electromagnetic power and the weak power of appearing at the time of β disintegration[1] were unified by Gauge theory.
○According to gauge theory, the place, i.e. particles （gauge bosons） exists between the elementary particles which carry out an interaction.
○Gauge boson (weak boson (W boson, Z boson)) is mediating the weak power of collapsing a neutron (a radioactive decay and).
○In 1983, the accelerator of CERN in Geneva discovered W boson and Z boson.

【Gauge theory】
○A gauge theory[2] is a type of field theory in which the Lagrangian (the difference between the kinetic energy and potential energy) is invariant. [3]
(☆ Since kinetic energy is expressed by a negative, "difference" is the sum of the two energies.)
1) In Quantum Field Theory, fields form particles, and particles form fields, and particles are medium to convey the power of fields. 
(As an example electromagnetic force acting between the electrons is caused by the exchange of photons. W and Z bosons mediate the weak force, gluons mediate the strong force. )[4], [5]
2) Moreover, in a vacuum, the amount of the field is slightly vibrate. Complete "Void" does not exist. [4]
