“…gauge mediated supersymmetry breaking gives the universality needed for this to vanish. There are currently three widely known classes of proposed solutions to the strong CP problem: (i) the axionic solution [365,366,367,368,369,370,371,372], (ii) the Nelson-Barr solution [373,374], and (iii) the m u = 0 solution [375].…”

After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of supersymmetry breaking, phenomenological constraints from electroweak symmetry breaking, flavor/CP violation, collider searches, and cosmological constraints including dark matter and implications for baryogenesis and inflation.

“…In hadronic axion models [6,7], axion multiplet couples to extra colored multiplets, which include colored fermions (called PQ fermions), to solve the strong CP problem. Even in DFSZ-type model [8,9] in which the ordinary Higgses have non-vanishing PQ charges, extra colored multiplets are likely to be introduced to avoid domain-wall problem. The saxion acquires thermal mass of the order of yT (with y being coupling constant) when the cosmic temperature T is higher than the mass of PQ fermions.…”

We consider supersymmetric model with Peccei-Quinn symmetry and study effects of saxion on the evolution of the universe, paying particular attention to the effects of thermal bath. The axion multiplet inevitably couples to colored particles, which induces various thermal effects. In particular, (i) saxion potential is deformed by thermal effects, and (ii) coherent oscillation of the saxion dissipates via the interaction with hot plasma. These may significantly affect the evolution of the saxion in the early universe.

We investigate the propagation of a charged particle in a spatially constant, but time dependent, pseudoscalar background. Physically this pseudoscalar background could be provided by a relic axion density. The background leads to an explicit breaking of Lorentz invariance; as a consequence the process p → pγ is possible and the background acts as a shield against extremely energetic cosmic rays, an effect somewhat similar to the GZK cut-off effect. The effect is model independent and can be computed exactly. The hypothetical detection of the photons radiated via this mechanism would provide an indirect way of verifying the cosmological relevance of axions. * On leave of absence from DECM and ICCUB, Universitat de Barcelona
