Research Abstract

In this work, we focus on nature of jets associated with hard process, and internal structures of the jets arising from the decay of heavy particle at LHC. We find such structure is important to improve the discovery potential of the LHC. Especially, westudy the ISR emission with degenerate new particles and dark matter, and top polarization measurement using jet substructure, measurement of scalar top mixing using the technique.
