Center-edge asymmetry as a discriminator of new physics indirect signatures at e+e- linear collider

Abstract

We explore the potential of a e+e- linear collider to disentangle new physics scenarios on μ+ μ- - pair production. R-parity violation and extensions of the Standard Model gauge structure offer two non-minimal realizations ofsupersymmetry at low energies that can lead to similar new physics signatures at e+ e- linear collider. We discuss the center-edge asymmetry which is useful for discriminating amongst these two new physics scenarios.
