| Outline of Final Research Achievements |
Higgs physics potential was evaluated for the future electron-proton colliders. By colliding one of the 7 TeV proton beams of the LHC (Large Hadon Collider) at CERN with an 60 GeV electron beam of a new power-saving Energy Recovery Linac, a new ep collision experiment can be performed (called LHeC). It was found that Higgs to b-quark coupling can be measured to better than 1%. Concerning a Higgs to invisibles decay, an upper limit of 5% branching ratio can be derived. Both results take only the statistical errors into account. These values are as good as, or even better than, the sensitivity at the high-luminosity LHC. By concurrently running both pp and ep experiments, a complementarity can be achieved and physics potential can be enhanced.
