The general structure of electromagnetic currents for electrodisintegration of nuclei near threshold, e(-) + A --> e(-) + A(1) + A(2) (A, A(1) and A(2) are arbitrary nuclei or hadrons with spins 0, 1/2 and 1), are established. Considering nuclei as elementary particles with the definite values of spin and space parity and using the conservation of hadronic electromagnetic current and P-invariance of hadron electromagnetic interaction, the spin structure of the amplitudes of the processes gamma* + A --> A(1) + A(2) is derived in terms of threshold electromagnetic form factors. The present formalism is valid for any nuclear structure and any reaction mechanism. The structure functions, which characterize the scattering electrons on the polarized target, are calculated as quadratic combinations of the form factors. These structure functions are used for the analysis of the problem of complete experiment for the full determination of all threshold form factors. P-odd part of electromagnetic current, induced by P-odd nuclear forces, is parametrized also in terms of the corresponding form factors. The processes with the following combinations of spins of hadrons e(-) + 1 --> e(-) + 0 + 0, e(-) + 1 --> e(-) + 1 + 0, e(-) + 1/2 --> e(-) + 1/2 + 1 and e(-) + 1/2 --> e(-) + 1/2 + 1/2, and with different combinations of space parities of nuclei A, A(1) and A(2), are examined within this approach.

Tensor form factors of B -> K-1 transition from QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30)
The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Electromagnetic form factors of octet baryons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2013-06-10)
The electromagnetic form factors of octet baryons are estimated within light cone QCD sum rules method, using the most general form of the interpolating current for baryons. A comparison of our predictions on the magnetic dipole and electric form factors with the results of other approaches is performed.
Angular coefficients of Z bosons produced in pp collisions at root S=8 TeV and decaying to mu(+)mu(-) as a function of transverse momentum and rapidity
Khachatryan, V.; et. al. (Elsevier BV, 2015-11-01)
Measurements of the five most significant angular coefficients, A(0) through A(4), for Z bosons produced in pp collisions at root S = 8 TeV and decaying to mu(+)mu(-) are presented as a function of the transverse momentum and rapidity of the Z boson. The integrated luminosity of the dataset collected with the CMS detector at the LHC corresponds to 19.7 fb(-1). These measurements provide comprehensive information about the Z boson production mechanisms, and are compared to the QCD predictions at leading orde...
Interacting electrons in a 2D quantum dot
Akman, N; Tomak, Mehmet (1999-04-01)
The exact numerical diagonalization of the Hamiltonian of a 2D circular quantum dot is performed for 2, 3, and 4 electrons. The results an compared with those of the perturbation theory. Our numerical results agree reasonably well for small values of the dimensionless coupling constant lambda = a/a(B) where a is the dot radius and a(B) is the effective Bohr radius. Exact diagonalization results are compared with the classical predictions, and they are found to be almost coincident for large lambda values.
Magnetic dipole moment of the light tensor mesons in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2010-07-01)
The magnetic dipole moments of the light tensor mesons f(2), a(2) and the strange K-2*(0)(1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f(2) and a(2) tensor mesons, while it has a small nonzero value for the neutral strange K-2*(0)(1430) tensor meson.
