“…This difference is most probably due to the different input parameters and the different methods employed. In Reference [42,43], it is indicated that the value of G Ds * Dsφ is 4.07 ± 0.71 GeV −1 in the framework of the three-point QCD sum rules. Besides of the perturbative part, the contributions of quark-quark, gluon-gluon, and quark-gluon condensate are considered in this work.…”

In this article, we calculate the form factors and the coupling constant of the vertex D * s D s φ using the threepoint QCD sum rules. We consider the contributions of the vacuum condensates up to dimension 7 in the operator product expansion. And all possible off-shell cases are considered, φ, D s and D * s , resulting in three different form factors. Then we fit the form factors into analytical functions and extrapolate them into time-like regions, which giving the coupling constant for the process.

“…These interaction terms can then be generalized by coupling the vector Galileon terms to arbitrary functions of A µ A µ . Many works have been done in the literature including the cosmology of vector Galileons [18], its Higgs mechanism [19], its relation to the bi-connection theory [20] and also the covariantization of the theory [21]. One of our aims in this paper is to ask which properties of the scalar Galileons in flat space will be inherited to the flat space vector Galileons.…”

One-loop corrections to vector Galileon theory

The effective action of the recently proposed vector Galileon theory is considered. Using the background field method, we obtain the one-loop correction to the propagator of the Proca field from vector Galileon self-interactions. Contrary to the so-called scalar Galileon interactions, the two-point function of the vector field gets renormalized at the one-loop level, indicating that there is no non-renormalization theorem in the vector Galileon theory. Using dimensional regularization, we remove the divergences and obtain the counterterms of the theory. The finite term is analytically calculated, which modifies the propagator and the mass term and generates some new terms also.Comment: 10 page

In this paper we study the possibility of assigning a geometric structure to the Lie groups. It is shown the Poincaré and Weyl groups have geometrical structure of the Riemann-Cartan and Weyl space-time respectively. The geometric approach to these groups can be carried out by considering the most general (non)metricity conditions, or equivalently, tetrad postulates which we show that can be written in terms of the group's gauge fields. By focusing on the conformal group we apply this procedure to show that a nontrivial 3-metrics geometry may be extracted from the group's Maurer-Cartan structure equations. We systematically obtain the general characteristics of this geometry, i.e. its most general nonmetricity conditions, tetrad postulates and its connections. We then deal with the gravitational theory associated to the conformal group's geometry. By proposing an Einstein-Hilbert type action, we conclude that the resulting gravity theory has the form of quintessence where the scalar field derivatively coupled to massive gravity building blocks.
