FY2022 Research Opportunities in High Energy Physics

archived

The DOE SC program in High Energy Physics (HEP) hereby announces its interest in new and renewal grant applications for support of research programs in high energy physics. The following program descriptions are offered to provide more in-depth information on scientific and technical areas of interest to HEP: Program Website: https://science.osti.gov/hep/ . The mission of the HEP program is to understand how the universe works at its most fundamental level, which is done by discovering the elementary constituents of matter and energy, probing the interactions between them, and exploring the basic nature of space and time. The scientific objectives and priorities for the field recommended by the High Energy Physics Advisory Panel (HEPAP) are detailed in its recent long-range strategic Particle Physics Project Prioritization Plan (P5), available at: https://science.osti.gov/~/media/hep/hepap/pdf/May-2014/FINAL_P5_Report_Interactive_060214.pdf . The HEP program focuses on three (3) experimental scientific frontiers: The Energy Frontier - where powerful accelerators are used to create new particles, reveal their interactions, and investigate fundamental forces using highly sensitive experimental detectors; The Intensity Frontier - where intense particle beams and highly sensitive detectors are used to pursue alternate pathways to investigate fundamental forces and particle interactions by studying events that occur rarely in nature, and to provide precision measurements of these phenomena; and The Cosmic Frontier - where non-accelerator-based experiments use measurements of naturally occurring cosmic particles and observations of the universe to probe fundamental physics questions and offer new insight about the nature of dark matter, cosmic acceleration in the forms of dark energy and inflation in the early universe, neutrino properties, and other phenomena. Together, these three interrelated and complementary discovery frontiers offer the opportunity to answer some of the most basic questions about the world around us. Also integral to the mission of HEP are crosscutting research areas that enable new scientific opportunities by developing the necessary tools and methods for discoveries: Theoretical High Energy Physics , where the vision and mathematical framework for understanding and extending the knowledge of particles, forces, space-time, and the universe are developed; Accelerator Science and Technology Research and Development , where the technologies and basic science needed to design, build, and operate the accelerator facilities essential for making new discoveries are developed; and Detector Research and Development , where the basic science and technologies needed to design and build high energy physics detectors essential for making new discoveries are developed.
