We calculate the asymmetries for the processes gamma + p --> Lambda(c)(+) (Sigma(c)(+)) + (D-0) over bar and gamma + p --> Lambda(c)(+)(Sigma(c)(+)) + (D*) over bar, induced by circularly polarized photons on a polarized proton target in the framework of an effective Lagrangian model. We found large and positive values for the asymmetry induced by the z-component of the proton polarization, in a wide energy region, from threshold up to E-gamma = 70 GeV In the case of pseudoscalar meson photoproduction, the predictions are qualitatively model-independent. For D*-photoproduction, there is a strong dependence of the asymmetries on NLambda(c)D(D*)-coupling constants.

Nucleon tensor form factors induced by isovector and isoscalar currents in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2011-10-11)
Using the most general form of the nucleon interpolating current, we calculate the tensor form factors of the nucleon within light cone QCD sum rules. A comparison of our results on tensor form factors with those of the chiral-soliton model and lattice QCD is given.
Associative photoproduction of charmed particles near threshold
Rekalo, MP; Tomasi-Gustafsson, E (Elsevier BV, 2001-02-15)
We calculate the cross section and the beam asymmetry for exclusive photoproduction of charmed particles near threshold (gamma + p --> Lambda (+)(c) (D-0) over bar), in the framework of an effective Lagrangian model. We discuss the sensitivity of these observables to the magnetic moment of the Lambda (c) baryon and of the coupling constant in the p Lambda D-c vertex. We show that exclusive measurements allow, in principle, to determine the magnetic moments of charmed baryons. (C) 2001 Published by Elsevier ...
Analysis of the Lambda b -> Lambda l(+)l(-) decay in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2010-03-01)
Taking into account the Lambda baryon distribution amplitudes and the most general form of the interpolating current of the Lambda(b), the semileptonic Lambda(b) --> Lambda l(+)l(-) transition is investigated in the framework of the light cone QCD sum rules. Sum rules for all 12 form factors responsible for the Lambda(b) --> Lambda l(+)l(-) decay are constructed. The obtained results for the form factors are used to compute the branching fraction. A comparison of the obtained results with the existing predi...
Isovector axial vector and pseudoscalar transition form factors of Delta in QCD
KÜÇÜKARSLAN, AYŞE; Ozdem, U.; Özpineci, Altuğ (2014-09-03)
We investigate the isovector axial vector and pseudoscalar form factors of Delta baryon by employing light-cone QCD sum rules. Numerical calculations show that the form factors can be well fitted by the exponential form. We make a comparison with the predictions of lattice QCD, chiral perturbation theory and quark model.
Least-squares finite element solution of Euler equations with adaptive mesh refinement
Akargün, Hayri Yiğit; Sert, Cüneyt; Department of Mechanical Engineering (2012)
Least-squares finite element method (LSFEM) is employed to simulate 2-D and axisymmetric flows governed by the compressible Euler equations. Least-squares formulation brings many advantages over classical Galerkin finite element methods. For non-self-adjoint systems, LSFEM result in symmetric positive-definite matrices which can be solved efficiently by iterative methods. Additionally, with a unified formulation it can work in all flight regimes from subsonic to supersonic. Another advantage is that, the me...
