The Higgs scalar of the whole particle picture is still mysterious. Nova days at LHC, we all are waiting some promising achievements. These days will most probably become the days of discovery of our mysterious scalar, Higgs boson, or with the popular name, the god particle. Witnessing a historical era as a physicist forces our generation more into science and physics of unknown. In the era of LHC, there are many new models trying to explain some specific problems in physics, which are also introducing us into a new world, or a recipe how to describe the new world, which is commonly named as physics beyond standard model. In this new world, besides the mysterious Higgs scalar, there are possibilities of existence of new heavy scalar and vector particles. The productions of these new charged and neutral scalars at forthcoming electron colliders such as ILC is one of the most interesting topics of physics beyond the standard model.
