Running Coupling with Minimal Length
In models with large additional dimensions, the GUT scale can be lowered to values accessible by future colliders. Due to modification of the loop corrections from particles propagating into the extra dimensions, the logarithmic running of the couplings of the Standard Model is turned into a power law. These loop-correction are divergent and the standard way to achieve finiteness is the introdu...
متن کاملRunning coupling constant and correlation length from Wilson loops
We consider a definition of the QCD running coupling constant α(μ) related to Wilson loops of size r×t with arbitrary fixed t/r. The schemes defined by these couplings are very close to the MS scheme (i.e. the one-loop perturbative correction to the coupling is small) for all values of t/r; in the t/r → ∞ limit, the “qq̄ force” scheme is recovered, where the coupling constant is related to the q...
متن کاملJosephson Junctions with Minimal Length
The minimal length of “one-dimensional” Josephson junctions, in which the specific bound states of the magnetic flux retain their stability is discussed numerically. Thereby, we consider as “long” every Josephson junction, in which there exists at least one nontrivial stable distribution of the magnetic flux for fixed values of all the physical and the geometrical parameters. Our results can be...
متن کاملIs minimal coupling procedure compatible with minimal action principle?
When space-time is assumed to be non-Riemannian the minimal coupling procedure (MCP) is not compatible, in general, with minimal action principle (MAP). This means that the equations gotten by applying MCP to the Euler-Lagrange equations of a Lagrangian L do not coincide with the Euler-Lagrange equations of the Lagrangian obtained by applying MCP to L. Such compatibility can be restored if the ...
