Hadronic axion, baryogenesis and dark matter
We investigate the prospects of an extra global symmetry, added to the Standard Model in the context of baryogenesis. The PQ symmetry is studied as an example. We show that the hadronic axion provides a protection of the B-asymmetry even if B − L=0 and that there are no limits on the neutrino masses. It is also shown that there is a crucial difference between the two possible invisible axion mo...
متن کاملGrand unification and heavy axion
We argue that sufficiently complex grand unified theories involving extra strong intractions that confine at very short distances, may lead to a heavy axion solution of the CP problem of QCD. This axion may have a mass within accessible energy range, and its low energy interactions emerge through mixing with axial Higgs boson(s). Another signature of this scenario is softly broken Peccei—Quinn ...
متن کاملQCD Axion and Quintessential Axion
The axion solution of the strong CP problem is reviewed together with the other strong CP solutions. We also point out the quintessential axion(quintaxion) whose potential can be extremely flat due to the tiny ratio of the hidden sector quark mass and the intermediate hidden sector scale. The quintaxion candidates are supposed to be the string theory axions, the model independent or the model d...
متن کاملA Quintessential Axion
The model independent axion of string theory has a decay constant of order of the Planck scale. We explore the properties of this quintessence candidate (quintaxion) in the scheme of hidden sector supergravity breakdown. In models allowing for a reasonable µ term, the hidden sector dynamics may lead to an almost flat potential responsible for the vacuum energy of (0.003 eV) 4. A solution to the...
متن کاملThe Mass of the Heavy Axion
If electroweak dynamical symmetry breaking is due to a chiral condensate of color sextet quarks, dynamics analagous to “walking technicolor” will enhance the condensate by orders of magnitude compared to the electroweak chiral scale. This enhancement compensates for the exponential suppression of electroweak scale color instanton interactions. As a result the η6 axion can naturally aquire an el...
