Neutrino-electron scattering is a purely leptonic fundamental interaction and therefore provides an important channel to test the Standard Model, especially at the low energy-momentum transfer regime. We derived constraints on neutrino nonstardard interaction couplings depending on model-independent approaches which are described by a four-Fermi pointlike interaction and the unparticle physics model with tensorial components. Data on (nu) over bar (e) - e and nu(e) - e scattering from the TEXONO and LSND experiments, respectively, are used. The upper limits and the allowed regions of scalar, pseudoscalar, and tensorial nonstandard interaction couplings of neutrinos are derived at 90% confidence level in both one-parameter and two-parameter analysis. New upper limits for tensorial unparticle physics coupling constants and mass parameters are also placed.

Constraints on nonstandard intermediate boson exchange models from neutrino-electron scattering Sevda, B.; Sen, A.; DEMİRCİ, MEHMET; DENİZ, MUHAMMED; Agartioglu, M.; Ajjaq, A.; KERMAN, SAİME; Singh, L.; Sonay, A.; Wong, H. T.; Zeyrek, Mehmet Tevfik (2017-08-21) Constraints on couplings of several beyond-Standard-Model-physics scenarios, mediated by massive intermediate particles including ( 1) an extra Z-prime, ( 2) a new light spin-1 boson, and ( 3) a charged Higgs boson, are placed via the neutrino-electron scattering channel to test the Standard Model at a low energy-momentum transfer regime. Data on (nu) over bar (e) - e and nu(e) - e scattering from the TEXONO and LSND, respectively, are used. Upper bounds to coupling constants of the flavor-conserving and fl...
On the Limits of Photocatalytic Water Splitting İpek Torun, Bahar; Üner, Deniz (2019-01-01) The major drawbacks on the limited H2 and O2 evolution activities of one-step photocatalytic water splitting systems are given here with the emphasis on charge recombination, back-oxidation reactions, and mass transfer limitations. Suppression of these unwanted phenomena is shown to be possible with the usage of small crystal-sized photocatalysts with low defect concentrations, presence of phase junctions, selection of co-catalyst that would be active for H2 evolution but inactive for O2 reduction, coating ...
A Comparative Study on Non-Linear State Estimators Applied to Sensorless AC Drives: MRAS and Kalman Filter Akin, Bilal; Orguner, Umut; Ersak, Aydin; Ehsani, Mehrdad (2004-11-06) In this paper, two different nonlinear estimators applied to sensorless AC drives, Kalman Filtering techniques (EKF and UKF) and Model Reference Adaptive System (back emf ans reactive power models), are discussed and compared to each other. Both of the observer types are studied and analyzed both experimentally and theoretically. In order to compare the observers precisely, the observers are tested under the identical conditions.
The effect of antisymmetric tensor unparticle mediation on the charged lepton electric dipole moment Iltan, E. O. (IOP Publishing, 2011-10-01) We study the contribution of antisymmetric tensor unparticle mediation to the charged lepton electric dipole moments and restrict the free parameters of the model by using the experimental upper bounds. We observe that the charged lepton electric dipole moments are strongly sensitive to the scaling dimension d(U) and the fundamental scales M(U) and Delta(U). The experimental current limits of electric dipole moments are reached for the small values of the scaling dimension d(U).
THE NEUTRAL HEAVY SCALAR PRODUCTIONS ASSOCIATED WITH Z(L) IN THE LITTLEST HIGGS MODEL AT ILC AND CLIC Cagil, A.; Zeyrek, Mehmet Tevfik (Jagiellonian University, 2011-01-01) In this work, the production processes of heavy neutral scalar and pseudoscalar associated with standard model gauge boson Z(L) at future e(+)e(-) colliders (ILC and CLIC) are examined. The total and differential cross-sections are calculated for the processes in the context of the littlest Higgs model. Dependence of production processes to littlest Higgs model parameters in the range of compatibility with electroweak precision measurements and decays to lepton-flavor violating final states are also analyze...
