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.
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 ...
The addition of pedals made steel guitar a country music staple, while blues and jazz musicians adopted the slide guitar, which utilized a similar gliding technique while holding the guitar upright.
He found that a vibrating metal string in a magnetic field generates a small current that can be amplified and sent to a loudspeaker; his steel guitar was the world's first electric guitar. [33] According to music writer Michael Ross, the first electrified stringed instrument on a commercial recording was a steel guitar played by Bob Dunn on a ...
Steel guitarists typically use the C6 neck for playing in a jazz or Western Swing style. The tuning makes it easier to play the more complex chord voicings commonly associated with these kinds of music, and the heavier strings on the bottom contribute a "thicker" or "fatter" tone. Below is a typical C6 copedent for a double–neck steel guitar.
Thomas Lewis Bradshaw (born February 14, 1935) is an American steel guitarist, journalist, music historian and businessman and who is known for his contributions to the pedagogy of steel guitar. He is a member of the Steel Guitar Hall of Fame (2006). [1] Bradshaw is noted for creating what is now an international standard for describing how a ...
Thousands of counterfeit Gibson electric guitars were seized at the Los Angeles-Long Beach Seaport, according to U.S. Customs and Border Protection. Federal authorities seize 3,000 fake Gibson ...
