The Stueckelberg extension of the Standard Model (StSM) consists of a gauge invariant kinetic term for a massive U(1) gauge field.Such a term can be implemented into the Lagrangian of the Standard Model without destroying the renormalizability of the theory and further provides a mechanism for mass generation that is distinct from the Higgs mechanism in the context of Abelian gauge theories.
In theoretical physics, scalar electrodynamics is a theory of a U(1) gauge field coupled to a charged spin 0 scalar field that takes the place of the Dirac fermions in "ordinary" quantum electrodynamics. The scalar field is charged, and with an appropriate potential, it has the capacity to break the gauge symmetry via the Abelian Higgs mechanism.

US Steel has agreed to be bought by Nippon Steel, Japan’s largest steelmaker, in a $14.1 billion deal. The deal marks the latest step in a gradual decline for the iconic 122-year old company ...
Moline Pressed Steel did not begin manufacturing toys until 1921. [2] Mr. Lundhal wanted to make something new, different, and durable for his son Arthur. [2] He designed and produced an all-steel miniature truck, reportedly a model of an International Harvester truck made from 18- and 20-gauge steel which had been discarded to the company's ...
The History Channel's original logo used from January 1, 1995, to February 15, 2008, with the slogan "Where the past comes alive." In the station's early years, the red background was not there, and later it sometimes appeared blue (in documentaries), light green (in biographies), purple (in sitcoms), yellow (in reality shows), or orange (in short form content) instead of red.
Graph of US iron and steel production, 1900–2014, data from USGS. The technological development of the US iron and steel industry has closely mirrored that of other countries. In the 1800s, the US switched from charcoal to coal in ore smelting, adopted the Bessemer process, and saw the rise of very large integrated steel mills.
Quantum electrodynamics is an abelian gauge theory with the symmetry group U(1) and has one gauge field, the electromagnetic four-potential, with the photon being the gauge boson. The Standard Model is a non-abelian gauge theory with the symmetry group U(1) × SU(2) × SU(3) and has a total of twelve gauge bosons: the photon , three weak bosons ...
