We study the behaviour under conformal transformations of energy and other charges in generic scalar - tensor models. This enables us to conclude that the ADM/AD masses are invariant under field redefinitions mixing metric and scalar despite the permitted slow asymptotic falloff of massless scalars.

Spherically symmetric solutions of Einstein plus non-polynomial gravities Deser, S.; Sarıoğlu, Bahtiyar Özgür; Tekin, Bayram (Springer Science and Business Media LLC, 2008-01-01) We obtain the static spherically symmetric solutions of a class of gravitational models whose additions to the General Relativity (GR) action forbid Ricci-flat, in particular, Schwarzschild geometries. These theories are selected to maintain the (first) derivative order of the Einstein equations in Schwarzschild gauge. Generically, the solutions exhibit both horizons and a singularity at the origin, except for one model that forbids spherical symmetry altogether. Extensions to arbitrary dimension with a cos...
Radiative decays of the heavy tensor mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2019-01-11) The transition form factors of the radiative decays of the heavy tensor mesons to heavy pseudoscalar and heavy vector mesons are calculated in the framework of the light-cone QCD sum rules method at the point Q(2) = 0. Using the obtained values of the transition form factors at the point Q(2) = 0, the corresponding decay widths are estimated. The results show that the radiative decays of the heavy-light tensor mesons could potentially be measured in the future planned experiments at LHCb.
Shortcuts to spherically symmetric solutions: a cautionary note Deser, S; Franklin, J; Tekin, Bayram (IOP Publishing, 2004-11-21) Spherically symmetric solutions of generic gravitational models are optimally, and legitimately, obtained by expressing the action in terms of the surviving metric components. This shortcut is not to be overdone; however, a one-function ansatz invalidates it, as illustrated by the incorrect solutions of Wohlfarth (2004 Class. Quantum Grav. 21 1927).
Electric dipole moments of charged leptons and lepton flavor violating interactions in the general two Higgs doublet model Iltan, EO (American Physical Society (APS), 2001-07-01) We calculate the electric dipole moment of the electron using the experimental result of the muon electric dipole moment and upper limit of the BR(mu-->e gamma) in the framework of the general two Higgs doubler model. Our prediction is 10(-32) e cm, which lies in the experimental current limits. Further, we obtain constraints for the Yukawa couplings )over bar>(D)(N,taue) and )over bar>(D)(N,tau mu). Finally, we present an expression which connects the BR(tau-->mu gamma) and the electric dipole moment of th...
Hybrid mesons in the context of the relativistic equation Zakout, I; Sever, Ramazan (Springer Science and Business Media LLC, 1997-08-01) The flux tube model of hybrid mesons is studied in the context of the relativistic equation in the adiabatic approximation. The moment of inertia of the rigid-rod flux tube is considered in the kinetic part of the interaction. The nonrelativistic and relativistic one scalar bead flux tube is integrated numerically and compared with the adiabatic flux tube small oscillation approximation. The relativistic scalar bead picture suggests that the lowest gluonic excitation of a massive gluon is color octet q (q) ...
