It turns out that quantum functions used in this kind of Lagrangian density have a de nite dimension. It isexplained why quantum functions that have the dimension [L 1] cannot describe particles that carry electric charge. It is shown that the 4-current of a quantum particle should satisfy further requirements. It follows that the pion and the WĄÀ must be composite particles. This outcome is inconsistent with the electroweak theory. It is also argued that the 125 GeV particle found recently by two LHC collaborations is not a Higgs boson but a ttĄ„meson. %K Lorentz scalar Lagrangian density %K electric charge %K Higgs boson %K ttĄ„meson %U http://www.ptep-online.com/index_files/2012/PP-31-03.PDF
