Axions were first introduced in connection with chiral symmetry but are now being looked for mainly as dark matter. In this paper we introduce a nonabelian analogue of axions which can also be potential candidates Their symmetries, generalizations the Peccei-Quinn symmetry, interesting their own right. Detailed analysis, using fermion measure and zeta function approaches, shows that these symme...

Baryon number is an accidental symmetry in the standard model, while Peccei-Quinn hypothetical which introduced to solve strong $CP$ problem. We study possible connections between and baryon symmetry. In this framework, axion identified as Nambu-Goldstone boson of violation. As a result, characteristic violating processes are predicted. developed general method determine lepton new scalar model.

Britain's National Portrait Gallery, which has recently acquired a striking new wing, has this autumn also obtained a very new kind of portrait. Artist Marc Quinn has created a 'genomic portrait' of Sir John Sulston, former director of the Wellcome Trust's Sanger Centre near Cambridge, who led the UK arm of the human genome project which announced completion of the first draft last year. As the...
