" Discovering the Higgs boson as well as measuring its properties are among the top priorities at the LHC, for good reasons. The identity of the Higgs is key to many mysteries surrounding physics at the TeV scale: Is the Higgs boson fundamental or composite? Is the physics at the weak scale predicted by the naturalness principle? Are there new particles responsible for reducing the fine-tuning in the Higgs mass? Does the mass of the W and Z bosons arise from the the Higgs mechanism? I will examine two ways of identifying the nature of the Higgs boson at the LHC. In the first talk I consider the production cross-section in the gluon fusion channel, while in the second talk I discuss the decay into ZZ final states. The identity of the Higgs could be revealed by precise measurements in these two channels. "
