We analyze the coupled [Formula: see text] supergravity and Yang-Mills system using holomorphy, near the rigid limit where the former decouples from the latter. We find that there appears generically a new mass scale around gMpl where g is the gauge coupling constant and Mpl is the Planck scale. This is in accord with the weak-gravity conjecture proposed recently.

Gauge Coupling Constant

Using the properties of the partition function for a Yang–Mills theory we compute simple relations among the renormalization constants. In the particular case of the background gauge field method we obtain that the all orders beta function for the gauge coupling constant contains only the first two orders coefficients different than zero and thus corresponds to the 't Hooft scheme.

Gauge Coupling Constant

By explicit solution of the one-loop finiteness conditions for all dimensionless coupling constants (i.e. the gauge coupling constant as well as Yukawa and quartic scalar-boson self-interaction coupling constants), two classes of grand unified theories characterized by renormalization-group beta functions which all vanish at least at the one-loop level are constructed and analyzed with respect to the (suspected) appearance of quadratic divergences, with the result that without exception in all of these models the masses of both vector and scalar bosons receive quadratically divergent one-loop contributions.

Gauge Coupling Constant

A natural generalization of the notion of the gauge coupling constant appearing in the covariant derivation operator is obtained by replacing it with a field Γ which takes values in the linear hermitian invertible mappings [Formula: see text] ([Formula: see text] is the Lie algebra of the gauge group G equipped with a G-invariant inner product). In this case the eigenvalues of Γ(x) for each point x from the space-time take the role of the usual single gauge coupling constant.
