The HFT Project aims to advance the understanding of charm mesons through innovative detection techniques. Our approach focuses on compelling scientific questions, including elementary charm cross-sections, parton energy loss, and charm flow. We propose a new detector designed to perform crucial measurements. The team is structured for effective collaboration and includes experts from BNL, UCLA, MIT, and others. This review outlines our major milestones, the properties of the proposed detector technology, and strategies for integration, highlighting our commitment to timely and impactful science.
