New data about electromagnetic form factors of the proton are discussed in terms of analyticity properties in space-like and in time-like region. From the constraints given by the Phragmen-Lindelof theorem, applied to the Sachs form factors, it turns out that the asymptotic regime can not be reached simultaneously for both form factors (electric and magnetic) up to s similar or equal to 14 GeV2. The angular dependence for the annihilation processes, such as (p) over bar + p e(+) + e(-), is sensitive to the asymptotic properties of form factors.

The electronic structure of GanPm(n+m = 5, 17, 29, 35), Ga13P4 (in SiO2) and Ga13P4 (in sodalite) clusters
Katırcıoğlu, Şenay (Elsevier BV, 2004-12-31)
The electronic structure of optimized GanPm(n+m=5, 17, 29, 35) isomers and Ga13P4 cluster in SiO2 matrix and sodalite cage has been studied by Hartree-Fock theory to find out the effect of cluster size and Ga-O bonds on the optical energy gap between LUMO and HOMO. It was found that the optical energy gap of Gal? clusters can be regulated by both the cluster size and the Ga-O interface satisfied by either SiO2 matrix or sodalite cage. The energy gap between LUMO and HOMO of Ga13P4 (in sodalite) cluster has ...
Nucleon electromagnetic form factors in QCD
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (American Physical Society (APS), 2008-06-01)
The nucleon electromagnetic form factors are calculated in a light cone QCD sum rules framework using the most general form of the nucleon interpolating current. Using two models for the distribution amplitudes, we predict the form factors. The predictions are also compared with existing experimental data. It is shown that our results describe remarkably well the existing experimental data.
The Wigner molecule in a 2D quantum dot
Akman, N; Tomak, Mehmet (1999-10-01)
The charge density and pair correlation function of three interacting electrons confined within a two-dimensional disc-like hard-wall quantum dot are calculated by full numerical diagonalization of the Hamiltonian. The formation of a Wigner molecule in the form of equilateral triangular configuration for electrons is observed as the size of the dot is increased.
THE TWO-DIMENSIONAL MAGNETO-POLARON IN THE STRONG-COUPLING REGIME
Erçelebi, Ayşe Çiğdem (IOP Publishing, 1989-04-03)
Within the framework of the strong-coupling polaron theory the problem of a two-dimensional electron coupled to LO phonons under an external magnetic field is studied. When a suitably modified coherent phonon state interrelating the magnetic field and the polaron counterparts of the problem is adopted, it is seen that the theory reproduces the desirable asymptotic limits attained by the perturbation or the usual adiabatic theories. Moreover, the theory indicates that an abrupt 'stripping transition' in the ...
The semileptonic B to K-1(1270,1400) decays in QCD sum rules
Dag, H.; Özpineci, Altuğ; Zeyrek, Mehmet Tevfik (IOP Publishing, 2011-01-01)
We analyze the semileptonic rare decays of the B meson to K-1(1270) and K-1(1400) axial vector mesons. The B -> K-1(1270, 1400)l(+)l(-) decays are significant flavor-changing neutral current decays of the B meson. These decays are sensitive to the new physics beyond the standard model (SM), since these processes are forbidden at tree level at SM. These decays occurring at the quark level via b -> sl(+)l(-) transition also provide new opportunities for calculating the CKM matrix elements V-bt and V-ts. In th...
