Higgs mass can be measured with 39 MeV statistical error.

Cross-section can be determined with 3.6% statistical error.

Results vary between energies and detector models.

Abstract

Precision measurements of SM Higgs recoil mass and cross-section are performed with the Higgs-Strahlung process ee -> Zh, with Z -> mumu and Z -> ee at 230 GeV and 250 GeV center of mass energies, presuming Mh=120GeV, assuming the integrated luminosity is 500 1/fb, based on full simulations of several detector models for the ILC. Results are given and compared in this article, of the two center of mass energies, and of several detector models. According to the studies, the Higgs mass can be determined with a statistical error of 39 MeV and 3.6% statistical error for the cross-section.
