Exotic baryon resonances and the model of chiral solitons

Abstract

We propose a novel electrochemical detector (ECD) to catalyze redox efficiently by electrodepositing Prussian blue (PB, ferric hexacyanoferrate) on the indium tin oxide (ITO) electrode. Capillary electrophoresis (CE) and amperometric methods were used. We investigated the PB surface properties by topography from atomic force microscopy (AFM). The PB film on dense and smooth surfaces could catalyze redox reaction efficiently. Compared with CE-ECD microchips using a bare-ITO electrode, the proposed CE-ECD microchip using a PB modified electrode has shown better sensitivity of the electropherograms. It has been verified that wide-ranging detection can be performed under the limits of 0.01 mM of dopamine and catechol respectively when we use a PB modified electrode.

Baryon spectrum in largeNcchiral soliton and in quark models

“…In the model [4] the equidistant behaviour was obtained for antidecuplet [45]. But such behaviour of antidecuplet spectrum does not follow in general from above consideration 10 . Quark contents of {27}-plet.…”

“…The connection between chiral soliton models and the quark models of exotic states has been discussed intensively, and different opinions have been revealed, from that both models are dual [43,10], or complementary to each other, to that they are essentially different, and predict different states: in particular, in [44] the states were predicted which are absent in the simplest quantization scheme of the chiral soliton models -the partners of states with different spin, but same flavor quantum numbers, including isospin. Here we show that some features of exotic baryons spectra obtained within the chiral soliton approach can be illustrated in terms of the quark model, as it was shown at first [45] for the case of antidecuplet.…”

“…Consideration of baryon states in the present paper is relevant independently on particular values of masses, widths and other properties of exotic baryon states measured experimentally. A detailed discussion of theoretical predictions of these states can be found in [7,8,9,10,11] 2 Some analogy with nuclei can be noted: two-, three-, etc. nucleon clusters play an important role in the structure of heavy nuclei, however, it is not possible to evaluate their properties from those of deuteron, helium etc., only.…”

“…We hope that the present calculation, taken together with the analogous calculation in [7,13,15,16,26,27,28,29] will contribute to the understanding of the overall picture of the baryonic mass spectrum and mass splittings in the Skyrme model, as well as to further computations of other nonperturbative, dimension-6 operator matrix elements between different baryon states [43,44].…”

“…To estimate baryon multiplets (8, 10, 10, 27, etc.) mass spectra, relevant mass differences and other baryon properties, various authors employed different types of methods and models [9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33].…”
