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

・In Weinberg-Salam theory, electromagnetic power and the weak power of appearing at the time of a radioactive decay were unified by Gauge theory.
・According to the 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 β disintegration).
　・In 1983, the accelerator of CERN in Geneva discovered W boson and Z boson.
