Phases of gauge theories
Spontaneous breaking of global and local symmetries. — The Higgs regime. — The Coulomb and infrared free phases. — Color confinement (closed and open strings). Does confinement imply chiral symmetry breaking? — Conformal regime. — Conformal window.
1 Spontaneous symmetry breaking
We will begin with a general survey of various patterns of spontaneous symmetry breaking in field theory. Our first task ...
