The GOAL of this first community workshop is to discuss "open questions" and "new ideas" to develop a focused physics program that will define the strategy and activities of the Energy Frontier during Snowmass 2021. The "open questions" and "new ideas" will also help define the letters of intent and contributed papers within the Energy Frontier. The invited plenary talks are expected to focus on the theme of this workshop and help us identify the gaps in previous work, highlight new ideas which can be explored by the proposed energy-frontier machines, and outline strategies to answer the main open questions. Plenty of time is allocated for discussion with the community. During this meeting we will also hear from the Monte Carlo Task Force about the needs and the strategy for MC production.
