After the discovery of the Higgs boson, the main objectives of the future high-energy physics are the precise measurement of Higgs properties and searches for new physics. These objectives strongly motivate the construction of an e+e- Higgs factory and a new pp collider with energy significantly higher than the LHC. The Higgs boson plays a crucial role in explaining spontaneous electroweak symmetry breaking and the mass generation of the known fundamental particles. It is thus important to measure precisely the Higgs-gauge couplings, the Higgs-Yukawa couplings and the Higgs self-couplings. A future Higgs factory would achieve such a goal significantly better than the LHC does. Such precision measurements can also unveil new physics that alter the Higgs properties. There are good reasons to expect that new physics should emerge at the TeV scale or above. A higher energy pp collider will be crucial for exploring new physics and the spectroscopy of any to-be-discovered particle at the LHC which may not be able to fully address the finding. During this program, we plan to address a series of issues on the physics, experiments and accelerator physics that are relevant to the future Higgs factories and pp colliders. Some of the questions that will be considered are -- What are the scientific goals of a Higgs factory and of a next generation of pp collider? -- What are the optimal design and technological challenges for the future colliders? -- What are the sensitivities of the scientific goals that can be reached with these future colliders? -- What are the requirements and challenges of instrumentation for accomplishing these measurements? -- What lessons have been learned from the LHC? One of the objectives of this program is to release one or several white papers documenting the physics goals, options of future colliders, and the reach of the related experiments. The white papers will be released to the particle physics community. To achieve this task, we are bringing theorists, experimentalists and accelerator physicists together, and provide a platform for the participants to promote stimulating discussions. As part of this program, a four-day conference will be organized on 19-22 January 2015.
