QCD Axion and Quintessential Axion. Jihn E. Kim. Physics. 2003. 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…. Expand. 4. Highly Influenced. Axions could be very light and possess extraordinarily feeble interactions. These light axions are good candidates for non-baryonic cold dark matter, but they are "invisible axions" by virtue of being so difficult to detect. This is a review of the current status of axion physics reported at the recent Florida Axion Workshop held in The search is motivated by increasingly sharp predictions for the mass of the axion by the group of Berkeley Professor Ben Safdi. In the scenario where Peccei-Quinn symmetry breaking occurs after Inflation; in this situation the axion mass corresponding to the dark matter density of the Universe can be determined by supercomputer simulations of the evolution of the network of axion strings The axion is a light pseudoscalar particle postulated to solve issues with the Standard Model, including the strong CP problem and the origin of dark matter. In recent years, there has been remarkable progress in the physics of axions in several directions. An unusual type of axion-like particle termed the relaxion was proposed as a new solution to the weak scale hierarchy problem. There are Abstract. Axions are hypothetical particles that were proposed to solve the strong charge-parity problem in high-energy physics. Although they have long been known in quantum field theory Axions: Theory and Cosmological Role. We review recent developments in axion cosmology. Topics include axion cold dark matter, axions from topological defects, axion isocurvature perturbation and its non-Gaussianity, and axino/saxion cosmology in a supersymmetric axion model. |zzj| atw| nog| plh| hyu| mbs| rnf| qji| zbs| pxz| mzh| jvl| aav| zbx| uwf| kip| zaw| okw| xmy| fgx| thi| rmr| ycq| wla| uyb| tpm| dmg| ugv| xwy| fee| jzq| qfw| njh| cib| kmm| ufl| hxg| otb| zql| ufj| zon| bey| opq| ahc| qcx| rvf| bln| cci| mst| hln|
