We propose a novel but natural definition of conserved quantities for gravity models of quadratic and higher order in curvature. Based on the spatial asymptotics of curvature rather than of metric, it avoids the more egregious problems-such as zero-energy '' theorems '' and failure in flat backgrounds-in this fourth-derivative realm. In D > 4, the present expression indeed correctly discriminates between second-derivative Gauss-Bonnet and generic, fourth-derivative actions.

Observing Higgs in weak boson fusion with forward jet tagging at the CERN CMS experiment Yıldız, Hatice Duran; Zeyrek, Mehmet Tevfik; Department of Physics (2002) The experimental observation of Higgs boson will be fundamental for a better understanding of the electroweak symmetry breaking mechanism. In this thesis the Standard Model Higgs boson decaying to a WW or ZZ pair in the weak boson fusion channel is studied for the LHC CMS experiment at CERN. This study utilizes the PYTHIA Monte Carlo event generator and the CMS detector simulation (CMS JET). Throughout this work, the observability of Higgs signal in the wide mass range is explored through WW -> lujj, ZZ ->?...
A Non-iterative Domain Decomposition Method for Finite Element Analysis of 3D Electromagnetic Scattering Problems Ozgun, Ozlem; Kuzuoğlu, Mustafa (2008-07-11) In this paper, we generalize this algorithm to 3D scattering problems, and we demonstrate that the algorithm is actually non-iterative in problems involving smooth convex geometries (such as sphere, cube, missile, cone, plate, etc.) and some special geometries (such as inlet). The most distinguished feature of the algorithm is the utilization of the locally-conformal perfectly matched layer (PML) method along the boundaries of the subdomains. In this algorithm, the original computational domain is partition...
New fuzzy extra dimensions from SU(N) gauge theories Kürkcüoğlu, Seçkin (2015-07-16) We start with an SU(N) Yang-Mills theory on a manifold M, suitably coupled to scalar fields in the adjoint representation of SU(N), which are forming a doublet and a triplet, respectively, under a global SU(2) symmetry. We show that a direct sum of fuzzy spheres S-F(2 Int) := S-F(2)(l) circle plus S-F(2)(l) circle plus S-F(2)(l + 1/2) circle plus S-F(2)(l - 1/2) emerges as the vacuum solution after the spontaneous breaking of the gauge symmetry and paves the way for us to interpret the spontaneously broken ...
An eigenfunction expansion for the Schrodinger equation with arbitrary non-central potentials Taşeli, Hasan; Uğur, Ömür (2002-11-01) An eigenfunction expansion for the Schrodinger equation for a particle moving in an arbitrary non-central potential in the cylindrical polar coordinates is introduced, which reduces the partial differential equation to a system of coupled differential equations in the radial variable r. It is proved that such an orthogonal expansion of the wavefunction into the complete set of Chebyshev polynomials is uniformly convergent on any domain of (r, theta). As a benchmark application, the bound states calculations...
New approach to conserved charges of generic gravity in AdS spacetimes Altas, Emel; Tekin, Bayram (American Physical Society (APS), 2019-02-12) Starting from a divergence-free rank-4 tensor of which the trace is the cosmological Einstein tensor, we give a construction of conserved charges in Einstein's gravity and its higher derivative extensions for asymptotically anti-de Sitter spacetimes. The current yielding the charge is explicitly gauge invariant, and the charge expression involves the linearized Riemann tensor at the boundary. Hence, to compute the mass and angular momenta in these spacetimes, one just needs to compute the linearized Riemann...
