Low-mass research in the field of physics typically refers to the study of objects with a small amount of mass, such as subatomic particles, atoms, or even celestial bodies like small planets or asteroids. This research area often investigates the properties, behavior, and interactions of these low-mass objects, and how they contribute to larger systems or structures in the universe. Low-mass research can be found in a variety of disciplines, including particle physics, astrophysics, and material science.
