  ABSTRACT: The Standard Model (SM) does not provide an empirical explanation for the variation in properties such as mass, charge, and spin among point-like fundamental particles. It also does not explain certain phenomena, including dark energy, dark matter, the observed asymmetry between matter and antimatter, neutrino mass and oscillation, and gravity. Additionally, some experimental observations differ from its predictions. This paper presents a new particle model (NPM), which characterizes fundamental particles as composite entities with internal structure. The NPM aims to address major anomalies and unresolved puzzles in the SM and offers testable predictions that extend beyond the SM.
