The Fermi-edge resonance problem for noncommuting scatterers, relevant for tunneling in mesoscopic systems, was investigated. It was shown that a resonance with tunable interaction strength, and thus with a variable power law exponent, can be realized. It was suggested that the control of scattering by varying the dot shape and coupling to the leads allows in exploring a wide range of exponents. It was found that the resonance is strongly enhanced by backscattering in a phase-sensitive fashion.
