WebNov 8, 2024 · A vector-related quantity whose invariance may not be readily-apparent is the scalar product of two vectors. As stated above, we can't declare it an invariant simply because it is a scalar, and in fact when expressed in terms of coordinates, it is by no means obvious that the answer comes out the same in both coordinate systems: WebExamples Scalar. The only fundamental scalar boson in the Standard Model of particle physics is the Higgs boson, the existence of which was confirmed on 14 March 2013 at the Large Hadron Collider by CMS and ATLAS. As a result of this confirmation, the 2013 Nobel Prize in physics was awarded to Peter Higgs and François Englert.; Various known …
