Title:
Symmetry breaking and the ABEGHHK’tH mechanism (Higgs effect)
Abstract: <p>The subject of this talk will be about a physical achievements which were first<br />
found mathematically and not by experiments : The ABEGHHK’tH mechanism (short<br />
for Higgs mechanism). This mechanism is defined in the framework of gauge theory by<br />
using the symmetry breaking. Thence, I will introduce gauge theory to give an idea of<br />
what the Higgs mechanism describes.<br />
Infinitesimal gauge transformations describe symmetries of the physical action and La-<br />
grangian which are not only valid for a solution of the Euler-Lagrange equations. We are<br />
going to define what an isotropy algebra is which is the essential component of symmetry<br />
breaking and, thus, of the mass of gauge boson.</p>
