Minimumsmassa

Minimumsmassa is a theoretical term used in discussions of models that involve mass as a parameter. It denotes the lower bound on mass required for a system to meet a set of criteria or constraints. The word combines "minimum" with "massa," the word for mass in several Romance languages, and is used informally rather than as an official unit.

As a nonstandard quantity, minimumsmassa has no fixed value. Its numerical value depends on the specific model, the chosen units, and the constraints imposed (such as stability, energy conditions, or experimental detectability). Different assumptions can yield different infimum or minimum values.

In physics, related notions appear in stellar astrophysics (lower mass limits for nuclear fusion), particle theory (bound-state formation thresholds), and cosmology (minimum mass for clumps or halos under certain scenarios). The concept is especially useful when comparing theories that differ in allowed mass ranges or in experimental sensitivity.

Mathematically, minimumsmassa can be defined as the infimum of masses m for which there exists at least one admissible configuration solving a given system of equations or inequalities. Computation typically uses optimization techniques, variational principles, or numerical simulations, and the result is model dependent.

The term is most often used informally in literature and discussions to label a boundary value rather than as a fixed physical constant.
