Boson is a term used to describe a type of subatomic particle that is responsible for transmitting force between particles. In physics, boson particles are categorized into two groups: gauge bosons and Higgs bosons. However, there are some synonyms that can be used instead of the word "boson". For instance, the term "vector boson" is used to describe the gauge bosons, while "scalar boson" describes the Higgs bosons. Other synonyms for boson include elementary particles and force carriers. Furthermore, there are also specific types of bosons such as gravitons and photinos, but these are not commonly used in general physics conversation.
