We analyze the annihilation cross section of the Dark Matter which interacts with the Standard Model sector over the scalar unparticle propagator. We observe that the annihilation cross section of the dark matter pair is sensitive to the dark matter mass and the scaling dimension of scalar unparticle. We estimate a range for the dark matter mass and the scaling dimension of scalar unparticle by using the current dark matter abundance.

The effect of curvature-scalar mixing on the annihilation cross sections of the dark matter scalar and unparticle dark matter
Iltan, E. O. (2011-12-01)
We consider the dark matter scalar in the Randall-Sundrum background and study the annihilation cross section if curvature-scalar mixing is switched on. In this case, in addition to the radion, the standard model Higgs scalar drives the annihilation, and it leads to considerable enhancement of the annihilation cross section. Furthermore, we take the unparticle, having a nonzero mass coming from the standard model Higgs-unparticle interaction at low energy levels, as a dark matter candidate and analyze the a...
The exclusive B ->pi l(+)l(-) and B ->rho l(+)l(-) decays in the general two Higgs doublet model
Erkol, G; Turan, Gürsevil (2002-02-01)
We study the differential branching ratio, branching ratio and the forward-backward asymmetry for the exclusive B --> pil(+)l(-) and B --> rhol(+)l(-) decays in the general two Higgs doublet model including the neutral Higgs boson erects. We analyze the dependencies of these quantities on the neutral Higgs boson contributions and the other model parameters. We observe that two Higgs doublet model with the neutral Higgs boson exchanges gives quite sizable contributions to these observables for both channels ...
The b -> sgg decay in the two and three Higgs doublet models with CP violating effects
Goksu, A; Iltan, EO; Solmaz, L (2001-04-20)
We study the decay width and CP asymmetry of the inclusive process b --> sgg (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyze the dependencies of the differential decay width and CP asymmetry to the s-quark energy E-s and CP violating parameter theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10(-2). Further, it is possible to predict the sign of C-7(eff) using the CP asymmetry.
The exclusive B -> (K, K*)l(+)l(-) decays in a CP softly broken two Higgs doublet model
Erkol, G; Turan, Gürsevil (2002-07-22)
We study the differential branching ratio, forward-backward asymmetry, CP-violating asymmetry, CP-violating asymmetry in the forward-backward asymmetry and polarization asymmetries in the B --> Kl(+)l(-) and B --> K*l(+)l(-) decays in the context of a CP softly broken two Higgs doublet model. We analyze the dependencies of these observables on the model parameters by paying a special attention to the effects of neutral Higgs boson (NHB) exchanges and possible CP-violating effects. We find that NHB effects a...
A linear variation of the thermal expansivity with frequency shifts for the translational mode in ammonia solid II near the melting point
Yurtseven, Hasan Hamit (Elsevier BV, 2007-11-01)
We examine here our spectroscopic modification of the Pippard relation which is a linear variation of the thermal expansivity alpha(p) with the frequency shifts (1/nu)(partial derivative nu/partial derivative p)(T) close to the melting point in ammonia solid II. For this we use our calculated frequencies for the Raman mode of nu (51 cm(-1)) in ammonia solid II for the pressures of 3.65, 5.02 and 6.57 kbars. We establish this linearity between alpha(p) and (I/nu)(partial derivative nu/partial derivative(p))(...
