Description
We investigate the possibility to identify the nature of spin of exotic charged particles at the
future e + e − collider in l ± + 2j + E T final state choosing IDM and MSSM as examples for the new
physics models with scalar and fermionic exotic charged particles, respectively. We choose four
benchmarks for the mass parameters for a significant deviation from the SM W + W − background.
We find that the cos θ of W boson constructed from jj pair and lepton have the potential to identify
the MSSM signal compared to the IDM signal in longitudinally polarized initial beams. A more
robust comparison is seen in the shape of the azimuthal angle of the W boson and charged lepton,
which can identify the IDM signal further if the beams are transversely polarized.
