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. 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 interaction...
