A Method for the Precision Mass Measurement of the Stop Quark at the International Linear Collider

Freitas, Ayres, Milstene, Caroline, Schmitt, Michael et al.

Understand

Many supersymmetric models predict new particles within the reach of the next generation of colliders.

  • For an understanding of the model structure and the mechanism(s) of symmetry breaking, it is important to know the masses of the new particles precisely.
  • In this article the measurement of the mass of the scalar partner of the top quark (stop) at an e+e- collider is studied.
  • A relatively light stop is motivated by attempts to explain electroweak baryogenesis and can play an important role in dark matter relic density.
