The Higgs mechanism is a well-known theory in particle physics that explains the origin of mass in fundamental particles. While the term "Higgs mechanism" is commonly used to describe this phenomenon, there are a number of synonyms that can be used to refer to this same concept. Some of these include the Brout-Englert-Higgs mechanism, the BEH mechanism, the Higgs field mechanism, and the Higgs-Kibble mechanism. Each of these terms refers to the same theoretical framework that describes how particles acquire mass through their interaction with the Higgs field, and each is commonly used within the field of particle physics.
