Theory-Experiment

To develop the fusion system of pheno-menology and data analysisBased on this system, we apply Monte Carlo system for experiments. To apply this system to hadron collider experiments in order to study the standard model (SM) and new physics (NP). To apply new tools to future experiments

Belle-II, LHC, etc.

Summary

35

Using the 21st centry concept of e-Science paradigm, we combine experiment, theory and computing for more efficient research process in hadron collider physics.

 The construction of this kind of new system of experiment, theory and computing can provide new reserach paradigm in other science areas.

Thank you
