Dualisation of the general scalar coset in supergravity theories

Yilmaz, NT
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.


Dualisation of the Salam-Sugin D-8 supergravity
Dereli, T; Yilmaz, NT (Elsevier BV, 2004-07-19)
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.

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...
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.
Scalar form factor of the nucleon and nucleon-scalar meson coupling constant in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2007-02-01)
Scalar form factor of the nucleon is calculated in the framework of light-cone QCD sum rules, using the most general form of the baryon current. Using the result on scalar form factor of the nucleon, the nucleon-scalar sigma and a(0) meson coupling constants are estimated. Our results on these couplings are in good agreement with the prediction of the external-field QCD sum rules method.
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...
