Goldstone 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...

متن کاملWorking Group on Goldstone Boson Product ion and Decay
312 Johan Bijnens et al. 1 I n t r o d u c t i o n Chiral symmetry plays a prominent role in low energy hadronic physics. The workshop was basically fully devoted to theoretical and experimental progress in this area. In our working group we discussed some topics not covered by the other three working groups (Bernstein and Kaiser (1997), Meif~ner and Sevior (1997), Drechsel (1997)) and in the v...
متن کاملExotic 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...
