A general analysis of polarization phenomena for coherent pion electroproduction on deuterons is presented. The spin and isospin structures of the gamma* + d --> d + P-0 amplitudes (where gamma* is a virtual photon) are established and relationships between meson electroproduction on deuterons and on nucleons are given in the framework of the impulse approximation. The reaction e + d --> e + d + pi(0) is investigated in detail, for a relatively large value of momentum transfer, 0.5 GeV2 less than or equal to -k(2) less than or equal to 2 GeV2, both at threshold and in the region of Delta-isobar excitation. Special attention is devoted to the sensitivity of different contributions to the exclusive cross section for d(e, epi(0))d, as the gamma*piomega form factor or the NN-potential. The predicted k(2)-dependence of the cross section agrees well with the available experimental data. (C) 2002 Elsevier Science (USA).

Forward energy flow, central charged-particle multiplicities, and pseudorapidity gaps in W and Z boson events from pp collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-01-01) A study of forward energy flow and central charged-particle multiplicity in events with W and Z bosons decaying into leptons is presented. The analysis uses a sample of 7 TeV pp collisions, corresponding to an integrated luminosity of 36 pb(-1), recorded by the CMS experiment at the LHC. The observed forward energy depositions, their correlations, and the central charged-particle multiplicities are not well described by the available non-diffractive soft-hadron production models. A study of about 300 events...
Distributed Optimal Control Problems Governed by Coupled Convection Dominated PDEs with Control Constraints Yücel, Hamdullah (2013-08-30) We study the numerical solution of control constrained optimal control problems governed by a system of convection diffusion equations with nonlinear reaction terms, arising from chemical processes. Control constraints are handled by using the primal-dual active set algorithm as a semi-smooth Newton method or by adding a Moreau-Yosida-type penalty function to the cost functional. An adaptive mesh refinement indicated by a posteriori error estimates is applied for both approaches.
Cross-section measurement for quasi-elastic production of charmed baryons in nu N interactions Kayis-Topaksu, A; et. al. (Elsevier BV, 2003-11-01) A study of quasi-elastic production of charmed baryons in charged-current interactions of neutrinos with the nuclear emulsion target of CHORUS is presented. In a sample of about 46000 interactions located in the emulsion, candidates for decays of short-lived particles were identified by using new automatic scanning systems and later confirmed through visual inspection. Criteria based both on the topological and kinematical characteristics of quasi-elastic charm production allowed a clear separation between ...
Transient and steady state photoelectronic analysis in TlInSe2 crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (Elsevier BV, 2011-08-01) The temperature and illumination effects on the transient and steady state photoconductivities of TlInSe2 crystals have been studied. Namely, two recombination centres located at 234 and at 94 meV and one trap center located at 173 meV were determined from the temperature-dependent steady state and transient photoconductivities, respectively. The illumination dependence of photoconductivity indicated the domination of sublinear and supralinear recombination mechanisms above and below 160 K, respectively. Th...
Dielectric and photo-dielectric properties of TlGaSeS crystals Qasrawi, A. F.; Abu-Zaid, Samah F.; Ghanameh, Salam A.; Hasanlı, Nızamı (2014-05-01) The room temperature, dark and photo-dielectric properties of the novel crystals TlGaSeS are investigated in the frequency, intensity and biasing voltage having ranges of similar to 1-120 MHz, 14-40 klux and 0-1 V, respectively. The crystals are observed to exhibit a dark high frequency effective dielectric constant value of similar to 10.65 x 10(3) with a quality factor of similar to 8.84 x 10(4) at similar to 120 MHz. The dielectric spectra showed sharp resonance-antiresonance peaks in the frequency range...
