2 天前 · The universal coupling is one of the most versatile couplings when it comes to connecting shafts at an angle. It can be used for shafts at 90 degrees to each other. It allows efficient transmission of power and torque between misaligned shafts at any angle, thus the name universal coupling.

The use of πNΔ gauge couplings in elastic πN

We perform a phenomenological analysis on the use of ?N?(1232) alternative couplings in ?N scattering, within a single and well-controlled dynamical model. We compare numerical results for the elastic cross section obtained using the conventional couplings, already adopted in several reaction calculations, with those obtained with the so-called ?spin-3/2 gauge-invariant? vertexes suggested recently.

The most important correction obtained from using multiple point parameter values (in a multi-parameter phase diagram instead of the single critical parameter value obtained say in the 1-dimensional phase diagram of a Wilson action) comes from including the influence of having phases confined solely w.r.t. …

We investigate the field dependence of the gauge couplings of N = 1 string vacua from the point of view of the low energy effective quantum field theory.

I've also seen the unitary gauge written (specifically in Srednicki's Quantum Field Theory) as phi' = frac{1}{sqrt{2}} egin{pmatrix} v + H \ 0 end{pmatrix} which seems equally valid since it's also an expansion around the vacuum expectation value of phi.
