dc.description.abstractIn this work we investigate a scalar field dark matter model with mass on the order of 100 MeV. We assume dark matter is produced in the process e(-) + e(+) -> phi + phi(*) + gamma which, in fact, could be a background for the standard process e(-) + e(+) -> nu + (nu) over bar + gamma extensively studied at LEP. We constrain the chiral couplings CL and C-R of the dark matter with electrons through an intermediate fermion of mass m(F) = 100 GeV and obtain C-L = 0.1(0.25) and C-R = 0.25(0.1) for the best-fit point of our x(2) analysis. We also analyze the potential of the International Linear Collider to constrain this scalar dark matter for two configurations: (i) a center-of-mass energy root s = 500 GeV and luminosity L = 250 fb(-1), and (ii) a center-of-mass energy root s = 1 TeV and luminosity L = 500 fb(-1). The differences of polarized beams are also explored to better understand the chiral couplings.en
