Ultraviolet behaviour of higher spin gauge field propagators and one loop mass renormalization
Ruben Manvelyan, Karapet Mkrtchyan, Werner Ruehl
The ultraviolet singular structure of the bulk-to-bulk propagators for higher spin gauge fields in space is analyzed in details. Possible interactions with the Higgs scal…
Generalized Curvature and Ricci Tensors for a Higher Spin Potential and the Trace Anomaly in External Higher Spin Fields in AdS_{4} Space
Ruben Manvelyan, Werner Ruehl
The curvature of a higher spin potential as constructed in a previous article of the same authors arXiv:0705.3528 is applied to the analysis of the linearized trace anomaly obtaine…
Conformal invariant powers of the Laplacian, Fefferman-Graham ambient metric and Ricci gauging
Ruben Manvelyan, Karapet Mkrtchyan, Ruben Mkrtchyan
The hierarchy of conformally invariant k-th powers of the Laplacian acting on a scalar field with scaling dimensions , k=1,2,3 as obtained in the recent work [1] is…
The Generalized Curvature and Christoffel Symbols for a Higher Spin Potential in AdS_{d+1} Space
Ruben Manvelyan, Werner Ruehl
The generalized curvature tensor and Christoffel symbols are determined in AdS_{d+1} background by a modified ansatz of the de Wit - Freedman type by imposing gauge invariance. The…
Conformal coupling of the scalar field with gravity in higher dimensions and invariant powers of the Laplacian
Ruben Manvelyan, D. H. Tchrakian
The hierarchy of conformally coupled scalars with the increasing scaling dimensions , connected with the -th Euler density in the corresponding space…
The structure of the trace anomaly of higher spin conformal currents in the bulk of
Ruben Manvelyan, Werner Ruehl
The two-point function of the conserved traceless spin- currents which are constructed from the scalar field is evaluated and renormalized by a dimensional regularizat…
