Calculation of η′ Decay Modes Using Chiral Perturbation Theory

In this paper, with the use of Chiral Perturbation theory (χPT), we have studied the η′ decays in to 3π and 2πη, after performing these reactions. The Scattering amplitude and decay width are calculated for different modes up to NLO. The Dalitz plot expansion and parameter fixing for each of them is also calculated. Experimental results are in good agreement with the obtained results. We compare our results with charged and neutral decay parameters with the most recent Particle Data Group results of these observables. At next-to-leading order, our results for decay widths of the charged (neutral) channel are Γ(η′→2πη)=83.6±0.8 (43.0±2.2) keV and Γ(η′→3π)=0.716±0.072 (0.320±0.079) keV. These results are in agreement with several other theoretical determinations and experimental findings.     

On the perturbation theory in spatially closed background

Recent studies have shown that searches in the mono-photon and missing energy final state can be used to discover dark matter candidates at the ILC. While an excess in this final state over the Standard Model background would indicate the existence of a dark sector, no detailed information about the internal structure of this sector can be inferred. Here, we demonstrate how just a few observables can discriminate between various realisations of dark sectors, including e.g. the spin of mediators.

Codes with girth 8 Tanner graph representation

Since short cycles are (empirically) detrimental to message passing, determining the girth of a given code is of interest in coding theory. Halford et al. studied codes which do not have a 4-cycle-free Tanner graph representation. It is natural to then ask which codes must have girth 8. In this paper, a new necessary condition is derived for codes to have girth 8. Halford et al. made statements about the girth of high rate well known codes but the girth of lower rate codes remain open. In this work, we investigate girth of low rate Reed–Muller, BCH and Reed–Solomon codes.     

Dispersive solid-phase extraction of risperidone from plasma samples using graphene oxide aerogels and determination with liquid chromatography

A graphene oxide-based aerogel was synthesized and applied to the extraction and the determinations with the high-performance liquid chromatography-ultraviolet detector. After the characterization of the produced graphene-aerogel, it was utilized as a dispersive solid-phase extraction sorbent for risperidone extraction from plasma samples. Aerogels are materials with a large surface area-to-mass ratio and plenty of core with functional groups which can easily attach to the analytes to extract them to the second phase. The suggested method determined risperidone in plasma samples in the wide dynamic range from 20 ng/ml to 3 μg/ml. The limits of detection and quantification of the developed method were calculated as 2.4 and 8.2 ng/ml, respectively. As a novel feature, the developed method has no need to precipitate plasma proteins, improving the analytical performance of the analysis. Also, for the first time, the produced materials were utilized for the extraction of risperidone from the plasma samples. The obtained results revealed that the developed approach could be employed as an accurate method for the quantification of risperidone in real plasma samples.
