What does renormalized mean?
Renormalized describes something that has been normalized again, usually because an earlier calculation, measurement, or model has changed. The term is most familiar from physics, where calculations may initially contain quantities that appear to be infinite. A renormalization procedure adjusts the relevant quantities so that the resulting theory or expression satisfies consistent normalization conditions and yields physically meaningful results. In less specialized writing, the word can simply mean that values or expressions have been put back into standard form after further modification. It is precise but technical, and the related verb “renormalize” is normally used in scientific contexts. The word also has an important historical dimension: techniques for renormalizing physical theories became central to the development of modern quantum field theory and the Standard Model.
Having undergone normalization again or a further normalization.
"The renormalized measurements agreed with the revised theoretical model."
Chiefly used in scientific and technical contexts.
To normalize again, especially by making a further adjustment to meet specified normalization conditions.
"The team renormalized the wave function after changing the model."
Common in mathematical physics and other technical disciplines; “renormalised” is the usual British spelling.
In physics, renormalization makes the infinite parts of a calculation disappear from the final answer — a mathematical disappearing act with major consequences.

Where does renormalized come from?
The word is formed from the prefix “re-” and “normalize,” meaning to normalize again. “Normalize” developed in the 19th century from “normal,” which comes through Latin from the Roman notion of a standard or rule. The combining form “-ize” was widely used in English for forming verbs associated with actions or processes. The prefixed form “renormalize” became especially prominent in 20th-century physics as physicists developed procedures for adjusting theories and quantities to meet normalization conditions.

How renormalized is actually used
Most common in technical and scientific writing, especially quantum field theory, particle physics, and related mathematical physics. Outside those fields, it is formal and comparatively uncommon. The spelling “renormalised” is standard in British English.
Easily confused with renormalized
“Normalized” means adjusted to a standard form, whereas “renormalized” indicates that such an adjustment has been carried out again, often after a further change.
