Dualisation of the Salam-Sugin D-8 supergravity

Dereli, T
Yilmaz, NT
The first-order formulation of the Salam-Sezgin D = 8 supergravity coupled to N vector multiplets is discussed. The non-linear realization of the bosonic sector of the D = 8 matter coupled Salam-Sezgin supergravity is introduced by the dualisation of the fields and by constructing the Lie superalgebra of the symmetry group of the doubled field strength.

Dualisation of the general scalar coset in supergravity theories
Yilmaz, NT (Elsevier BV, 2003-08-04)
The dualised formulation of the symmetric space sigma model is peformed for a general scalar coset G/K where G is a maximally non-compact group and K is it's maximal compact subgroup. By using the twisted self-duality condition the general form of the first-order equations are obtained. The results are applied to the example of SL(2, R)/SO(2) scalar manifold of the IIB supergravity.
General analysis of the polarization effects in N+N -> d+P processes
Yalcin, C; Rekalo, MP; Koru, H (IOP Publishing, 1998-05-01)
We establish the spin structure of matrix elements for N + N --> d + P processes, where P is a pi- or eta-meson, in terms of six scalar amplitudes. Isospin invariance of a strong interaction results in definite symmetry properties of these amplitudes relative to the change cos theta --> -cos theta; where theta is the P-meson production angle. We parametrize all possible polarization observables in n + p --> d + P using a formalism of structure functions and calculate these structure functions in terms of sc...
Polynomial solutions of the Schrodinger equation for the generalized Woods-Saxon potential
Berkdemir, C; Berkdemir, A; Sever, Ramazan (American Physical Society (APS), 2005-08-01)
The bound state energy eigenvalues and the corresponding eigenfunctions of the generalized Woods-Saxon potential are obtained by means of Nikiforov-Uvarov (NU) method. Certain bound states of the Schrodinger equation for the potential are calculated analytically and the wave functions are found in terms of the Jacobi polynomials. It is shown that the results are in good agreement with those obtained previously.
Semileptonic B-q -> D-q*l nu (q=s,d,u) decays in QCD sum rules
Azizi, K.; Bayar, M. (American Physical Society (APS), 2008-09-01)
The form factors relevant to B-q -> D-q*(J(P) = 1(-))l nu (q = s, d, u) decays are calculated in the framework of the three point QCD sum rules approach. The heavy quark effective theory prediction of the form factors as well as 1/m(b) corrections to those form factors are obtained. A comparison of the results for the ratio of form factors at zero recoil limit and other values of q(2) with the predictions of the subleading Isgur-Wise form factor application for B -> D*l nu is presented. The total decay widt...
Hamiltonian electric/magnetic duality and Lorentz invariance
Deser, Stanley; Sarıoğlu, Bahtiyar Özgür (Elsevier BV, 1998-01-01)
In (3+1) Hamiltonian form, the conditions for the electric/magnetic invariance of generic self-interacting gauge vector actions and the definition of the duality generator are obvious. Instead, (3+1) actions are not intrinsically Lorentz invariant. Imposing the Dirac–Schwinger stress tensor commutator requirement to enforce the latter yields a differential constraint on the Hamiltonian which translates into the usual Lagrangian form of the duality invariance condition obeyed by Maxwell and Born-Infeld theor...
