The magnetic and quadrupole moments of the vector and axial-vector mesons containing a heavy quark are estimated within the light-cone sum rules method. Our predictions on magnetic moments for the vector mesons are compared with the results obtained by other approaches.

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.
Magnetic moment of the rho meson in QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2003-09-01)
The magnetic moment mu of the rho meson is studied in QCD light cone sum rules, and it is found that mu=(2.3+/-0.5), in units of e/2m(rho). A comparison of our result on the magnetic moment of the rho meson with the predictions of the other approaches is presented.
Shortcuts to high symmetry solutions in gravitational theories
Deser, S; Tekin, Bayram (IOP Publishing, 2003-11-21)
We apply the Weyl method, as sanctioned by Palais' symmetric criticality theorems, to obtain those-highly symmetric-geometries amenable to explicit solution, in generic gravitational models and dimension. The technique consists of judiciously violating the rules of variational principles by inserting highly symmetric, and seemingly gauge fixed, metrics into the action, then varying it directly to arrive at a small number of transparent, indexless, field equations. Illustrations include spherically and axial...
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...
Multidimensional quantum tunneling in the Schwinger effect
Dumlu, Cesim K. (American Physical Society (APS), 2016-03-22)
We study the Schwinger effect, in which the external field having a spatiotemporal profile creates electron-positron pairs via multidimensional quantum tunneling. Our treatment is based on the trace formula for the QED effective action, whose imaginary part is represented by a sum over complex worldline solutions. The worldlines are multiperiodic, and the periods of motion collectively depend on the strength of spatial and temporal inhomogeneity. We argue that the classical action that leads to the correct ...
