Exotic Goldstone Particles: Pseudo-Goldstone Boson and Goldstone Fermion
This essay describes two exotic Goldstone particles. One is the pseudoGoldstone boson which is related to spontaneous breaking of an approximate symmetry. The other is the Goldstone fermion which is a natural result of spontaneously broken global supersymmetry. Their realization and implication in high energy physics are examined.
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 Return of the Prodigal Goldstone Boson
We propose that the mass of the η meson is a particularly sensitive probe of the properties of finite energy density hadronic matter and quark gluon plasma. We argue that the mass of the η excitation in hot and dense matter should be small, and therefore that the η production cross section should be much increased relative to that for pp collisions. This may have observable consequences in dile...
متن کاملGoldstone Boson Production and Decay
Various topics in and around Goldstone Boson Production and Decay in CHPT are discussed, in particular I describe some of the progress in p Chiral Perturbation Theory Calculations, the progress in calculating hadronic contributions to the muon anomalous magnetic moment, here comparing the two latest results of the light-by-light in some detail. I also present some progress in various η and K de...

We propose that the mass of the h8 meson is a particularly sensitive probe of the properties of finite energy density hadronic matter and quark-gluon plasma. We argue that the mass of the h8 excitation in hot and dense matter should be small, and, therefore, that the h8 production cross section should be much increased relative to that for pp collisions. This may have observable consequences in...
