Se p 19 99 Supersymmetry approach in the field theory of ergodicity breaking transitions ∗
نویسنده
چکیده
The supersymmetry (SUSY) self–consistent approximation for the model of non–equilibrium thermodynamic system with quenched disorder is derived by making use of generalized second Legendre transformation. The equations for adiabatic and isothermal susceptibilities, memory and field induced parameters and the temperature of ergodicity breaking transition are obtained on the basis of asymptotic analysis of dynamic Dyson equations. The temperature of ergodicity breaking transition is calculated as a function of quenched disorder intensities. PACS numbers: 05.70.Ln, 11.30.Pb, 64.60.–i

The effective motion equation that describes the different monomer alternation along the heteropolymer chain is proposed. On its basis the supersymmetry field scheme that allows to obtain the equations for the structure factor and Green function is built up. The memory and ergodicity breaking effects are investigated depending on the temperature and quenched disorder of the monomer alternation....

We present a combined study of the muon anomalous magnetic moment, aμ ≡ (g− 2)μ/2, and b → sγ decay in the minimal supersymmetric standard model with gauge-mediated supersymmetry-breaking. Combining new experimental data on aμ and the branching ratio for b → sγ, useful limits on the parameter space of these models are derived. Bounds on supersymmetric particle masses as a function of tanβ are a...
متن کاملSe p 19 93 R Symmetry Breaking Versus Supersymmetry Breaking
We point out a connection between R symmetry and supersymmetry breaking. We show that the existence of an R symmetry is a necessary condition for supersymmetry breaking and a spontaneously broken R symmetry is a sufficient condition provided two conditions are satisfied. These conditions are: genericity, i.e. the effective Lagrangian is a generic Lagrangian consistent with the symmetries of the...

Considerable progress has been achieved recently in the observation of string breaking within non-Abelian Higgs models, by use of multi-channel methods allowing for broken string states. Similarly, in pure gauge theory this approach has been shown to reveal string breaking for color charges in the adjoint represenation. For QCD with dynamical fermions, one needs substantial progress in noise re...
متن کاملNoise-induced transitions vs. noise-induced phase transitions
I will briefly review the field of noise-induced phase transitions, emphasizing the main differences with the phase-induced transitions and showing that they appear in different systems. I will show that a noise-induced transition can disappear after a suitable change of variables and I will also discuss the breaking of ergodicity and symmetry breaking that occur in noise-induced phase transiti...
