We compute the electromagnetic structures of D and D* mesons, the singly charmed Sigma(c) Omega(c), and the doubly charmed Xi(cc), Omega(cc) baryons in 2+1 flavor Lattice QCD. We extract the charge radii and the magnetic moments of these hadrons. In general, charmed hadrons are found to be more compact as compared to light hadrons. The magnetic moments of the singly charmed baryons are found to be dominantly determined by the light quark and the role of the charm quark is significantly enhanced when it is doubly represented.

Vector and axial-vector couplings of D and D* mesons in 2+1 flavor lattice QCD Can, K. U.; ERKOL, GÜRAY; Oka, M.; Özpineci, Altuğ; Takahashi, T. T. (2013-02-12) Using the axial-vector coupling and the electromagnetic form factors of the D and D* mesons in 2 + 1 flavor lattice QCD, we compute the D*D pi, DD rho and D*D*rho coupling constants, which play an important role in describing the charm hadron interactions in terms of meson-exchange models. We also extract the charge radii of D and D* mesons and determine the contributions of the light and charm quarks separately.
Magnetic properties of multiband U=infinity Hubbard model on anisotropic triangular and rectangular lattice strips CHERANOVSKII, VO; Esentürk, Okan; PAMUK, HO (1998-11-01) We study the dependence of the ground state spin of a multiband Hubbard model with infinite electron repulsion on anisotropic triangular and rectangular lattice strips on the model parameters. Considering the results of numerical calculations for the exact spectra of finite triangular lattice strips at different values of hopping integrals, we show the existence of a type of magnetic transitions with the jump of the ground state spin between minimal and maximal values. This transition is found only for spec...
Pseudospin and spin symmetry in the Dirac equation with Woods-Saxon potential and tensor potential AYDOĞDU, OKTAY; Sever, Ramazan (2010-01-01) The Dirac equation is solved approximately for the Woods-Saxon potential and a tensor potential with the arbitrary spin-orbit coupling quantum number kappa under pseudospin and spin symmetry. The energy eigenvalues and the Dirac spinors are obtained in terms of hypergeometric functions. The energy eigenvalues are calculated numerically.
Strong Coupling Constants of Negative Parity Heavy Baryons with pi and K Mesons Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2017-01-01) The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light pi and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-sextet, sextet-antitriplet, and antitriplet-antitriplet transitions can be described by only one corresponding function. The pollution arising from the positive to positive, positive to negative, and negative to positive parity baryons transitions is eliminated by...
Energy spectrum of a 2D Dirac oscillator in the presence of a constant magnetic field and an antidot potential Akçay, Hüseyin; Sever, Ramazan (2016-07-04) We investigate the energy spectrum and the corresponding eigenfunctions of a 2D Dirac oscillator confined by an antidot potential in the presence of a magnetic field and Aharonov-Bohm flux field. Analytical solutions are obtained and compared with the results of the Schrodinger equation found in the literature. Further, the dependence of the spectrum on the magnetic quantum number and on the repulsive potential is discussed.
