Quenched Supersymmetry

چکیده
We study the effects of quenching in Super-Yang-Mills theory. While supersymmetry is broken, the lagrangian acquires a new flavour U(1 | 1) symmetry. The anomaly structure thus differs from the unquenched case. We derive the corresponding low-energy effective lagrangian. As a consequence, we predict the mass splitting expected in numerical simulations for particles belonging to the lowest-lying supermultiplet.

Super-Yang-Mills on the Lattice: Weak and Strong Coupling Limits
We present a general review about the N=1 supersymmetric SU(Nc) Yang-Mills on the lattice focusing our attention on the quenched approximation in supersymmetry. Finally we analyse and discuss the recent results obtained at strong coupling and large Nc for the mesonic and fermionic propagators and spectrum.
متن کاملQuenched Two Dimensional Supersymmetric Yang-Mills Theory
By studying the pure Yang-Mills theory on a circle, as well as an adjoint scalar coupled to the gauge field on a circle, we propose a quenching prescription in which the combination of the spatial component of the gauge field and P is treated as a dynamic variable. Averaging over momentum is not necessary, therefore the usual ultraviolet cut-off is eliminated. We then apply this prescription to...

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 an...

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....
متن کاملPartially quenched chiral perturbation theory in the epsilon regime at next-to-leading order
We calculate the partition function of partially quenched chiral perturbation theory in the epsilon regime at next-to-leading order using the supersymmetry formulation developed by Sharpe and Shoresh. We include a nonzero imaginary chemical potential and show that the finite-volume corrections to the low-energy constants Σ and F for the partially quenched partition function, and hence for spect...
