35. Kihyeon Cho 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.
