Goldstone Bosons
The paper concerns the effective field theory methods used to study the low energy structure of systems with a spontaneously broken symmetry. I first explain how the method works in the context of quantum chromodynamics and then discuss a few general aspects, related to the universality of effective theories. In particular, I compare some of the effective field theories used in condensed matter...
متن کاملPhonons as Goldstone bosons
The implications of the hidden, spontaneously broken symmetry for the properties of the sound waves of a solid are analyzed. Although the discussion does not go beyond standard wisdom, it presents some of the known results from a different perspective. In particular, I argue that, as a consequence of the hidden symmetry, the equations of motion for a sound wave necessarily contain nonlinear ter...
متن کاملAccidental Goldstone Bosons
We study vacuum alignment in theories in which the chiral symmetry of a set of massless fermions is both spontaneously and explicitly broken. We find that transitions occur between different phases of the fermions’ CP symmetry as parameters in their symmetry breaking Hamiltonian are varied. We identify a new phase that we call pseudoCP-conserving. We observe first and second-order transitions b...
متن کاملHolographic pseudo-Goldstone boson
The LHC experiment will soon probe how W and Z bosons acquire their masses. So far we have only indirect hints about the actual mechanism of electroweak symmetry breaking. The standard model (SM) introduces a weakly coupled fundamental scalar field—the Higgs field— whose condensation breaks the electroweak symmetry. This simple picture is consistent with precision electroweak measurements, if t...
متن کاملThe Character of Goldstone Bosons
In the strong interaction spectrum the pion is identified as both a Goldstone mode, associated with Dynamical Chiral Symmetry Breaking (DCSB), and a bound state composed of uand d-quarks. This dichotomy is remarkable because, while mρ/2 ∼ mN/3 ∼ 350 MeV=: Mq, the constituent quark mass, mπ/2 is only ≈ 0.2Mq; i.e., the pion is much lighter than comparable bound states. Mq is the “effective mass”...
