Beam parameters optimisation at CLIC for the threshold scan of the process $e^+e^-\rightarrow \widetilde{\mu}_{R}^{+}\widetilde{\mu}_{R}^{-}\rightarrow \mu ^+ \mu^-\widetilde{\chi}_{1}^{0}\widetilde{\chi}_{1}^{0}$ at multi-TeV energies

CLIC offers the ability to measure various proprieties of potential new heavy states with high precision. Beam-beam effects that inevitably occur at the interaction point affect the precision of physics measurements. The beam parameters can be optimised for a given energy and physics benchmark to minimise their impact. In this paper, the smuon mass extraction and spin determination through a threshold scan are investigated. Two main options realise a centre-of-mass energy scan at CLIC, which are either to keep the number of particles and the pulse length unchanged or to reduce the number of particles but to increase the pulse length. We compare the physics potential of both scenarios including the impact of beam polarisation.
