by J. Golak, R. Skibiński, W. Glöckle, H. Kamada, A. Nogga, V. D. Efros, W. Leidemann, G. Orl, E. L. Tomusiak , 2008
"... A benchmark is set on the three–nucleon photodisintegration calculating the total cross section with modern realistic two – and three–nucleon forces (AV18, UrbIX) using both the Faddeev equations and the Lorentz Integral Transform method. This test shows that the precision of three-body calculations ..."

CLAS+FROST: new generation of photoproduction experiments at Jefferson Lab.

by E. Pasyuk , 906
"... Spectrometer (CLAS) and availability of circularly and linearly polarized tagged photon beams provide unique conditions for this type of experiments. Recent addition of the Frozen Spin Target (FROST) gives a remarkable opportunity to measure double and triple polarization observables for different p ..."

ANOMALOUS DIMENSIONS OF TWIST-2 OPERATORS AND POMERON

by Coden Fizbe, In N Susy, L. N. Lipatov , 2008
"... We review the BFKL approach to the Regge processes in QCD and show that in the multi-colour QCD the BKP equations for composite states of several Reggeized gluons are integrable. The relation between pomeron and graviton in N = 4 SUSY is investigated. The maximal transcendentality hypothesis gives u ..."

Using also the asymptotic Bethe an-zatz and a model for wrapping effects, we find the anomalous dimension for twist-2 operators in four loops, in an agreement with the BFKL and double-logarithmic predictions.

Pion photoproduction on the nucleon in the quark model

by Qiang Zhao, J. S. Al-khalili, Z. -p. Li, R. L. Workman , 2002
"... We present a detailed quark-model study of pion photoproduction within the effective Lagrangian approach. Cross sections and single-polarization observables are investigated for the four charge channels, γp → π + n, γn → π − p, γp → π 0 p, and γn → π 0 n. Leaving the πN ∆ coupling strength to be a f ..."

free parameter, we obtain a reasonably consistent description of these four channels from threshold to the first resonance region. Within this effective Lagrangian approach, strongly constrainted by the quark model, we consider the issue of double-counting which may occur if additional t

DIFFRACTION AND VECTOR MESON PRODUCTION AT HERA MIKHAIL KAPISHIN

by For The H, Zeus Collaborations , 2008
"... Results of new measurements of diffractive cross sections in deep-inelastic scat-tering (DIS) and photo-production at HERA are presented. The cross sections of dijet and open charm production are compared with next-to-leading order (NLO) QCD predictions based on parton distribution functions obtaine ..."

A combined NLO QCD fit to the inclusive and dijet DIS data is performed to determine diffractive quark singlet and gluon densities with a bet-ter precision.

New Spectrophotometric Methods for the Determination of Moxifloxacin in Pharmaceutical Formulations

by Abdalla A Elbashir , Sara A M Ebraheem , Alawia H E Elwagee , Hassan Y Aboul-Enein , 2013
"... Abstract Two rapid, simple and sensitive spectrophotometric methods for the quantitative analysis of moxifloxacin (MOX) in pharmaceutical formulations have been described. The first method (A) involves reaction of MOX with 1,2-naphthoquinone-4-sulphonate (NQS) in alkaline medium (pH 11.0) which res ..."

Under the optimized reaction conditions, Beer ' s law correlation of the absorbance with MOX concentration was obtained in the range of 2.5-20 and 0.5-30 μgmL -1 for method A

The contributions of the diffractive production and direct knockout processes to the φ photoproduction from proton are calculated with the use of Pomeron-photon analogy and a relativistic harmonic oscillator quark model. We find that some of the double polarization observables are very sensitive to ..."

nucl-th/9702015 (REVISED) Polarization Observables in φ Meson Photoproduction and the Strangeness Content of the Proton

by Er I. Titov A, Yongseok Oh B, Shin Nan Yang B , 2008
"... The contributions of direct knockout processes, in addition to the diffractive production and one-pion-exchange processes associated with the φρπ and φγπ couplings, to the polarization observables of the φ photoproduction from proton are calculated. We make use of Pomeron-photon analogy and a relati ..."

relativistic harmonic oscillator quark model. We find that some of the double polarization observables are very sensitive to a possible s¯s admixture in the proton. It arises from the difference in the spin structures of the three different amplitudes. This suggests that such measurements could be very useful
