Experimental results on KLK_L decays

Recent measurements by the NA48 at CERN of selected $K_L$ decays are presented. These are the branching ratios and form factors for channels K_L\to \pi^{\pm}\pi^0\e^{\mp}\nu_e (final result), $K_L\to\pi^{\pm}e^{\mp}\nu_e$ and $K_L\to e^+e^-e^+e^-$ (preliminary results).Comment: 4 pages, 5 figures, talk given at QCD'04 Conference, Montpellier, France, 5-9 July 200

Charmed-strange Mesons Experimental Results

Two new states in the charm strange sector, DsJ(2317) and DsJ(2460), have recently been discovered at electron positron collider experiments. The new states are first observed in the dominant Ds pi0 and Ds* pi0 modes respectively and are very narrow. They are consistent with 0+ and 1+ P-wave charm anti-strange mesons. The DsJ(2460) meson is also observed in Ds gamma and Ds pi+ pi- modes. A review of the discoveries and possible explanations is given.Comment: 5 pages, 5 figures and 1 table.

Experimental Results of a Wind Energy Conversion System with STATCOM Using Fuzzy Logic Controller

This paper describes a complete implementation of the experimental voltage regulation of a wind energy conversion system using STATCOM. Firstly conventional control technique is used which is proportional plus integral controller. The control technique is performed using a PC computer through a suitable interfacing and opt-isolating facilities. Secondly fuzzy logic controller is facilitated in this scheme to improve the performance of the experimental setup. Several efforts are done to choose the suitable gains of the fuzzy controller to achieve superior performance of the wind system. Experimental results of the system show the effectiveness of the proposed technique in regulating the output voltage. Thanks to the operation of the STATCOM in controlling the reactive power of the system to fix the output voltage at the desired value regardless of the wind speed

Experimental Results in Heavy Flavor Physics

The interplay of experiment and theory is explored in the context of current data on b and c decay. Measurements of |Vcb| and |Vub| are extracted from existing data. Conservative estimates give |Vcb|=(42.4 +/- 1.2{exp} +/- 2.3{thy})x10^{-3} and |Vub|=(3.90 +/- 0.16{exp} +/- 0.53{thy})x10^{-3}. Using these values along with data on Bd, Bs mixing and CP violation in the K_{Long} system, the allowed region of the CKM parameters rho and eta is derived. Tests of factorization in two-body hadronic B decays to one heavy and one light meson are shown and compared with modern theories which are also used to see if there is new physics in two-body B decays to light mesons. The two new narrow D_{sJ} states, discovered by BaBar and CLEO, respectively, are interpreted in light of the observation of these states in B decays by Belle.Comment: Plenary talk at International Europhysics Conference on High Energy Physics EPS (July 17th-23rd 2003) in Aachen, Germany, 16 pages, 37 figures.

Inviscid Flow Field Effects: Experimental results

The aero-optical distortions due to invisid flow effects over airborne laser turrets is investigated. Optical path differences across laser turret apertures are estimated from two data sources. The first is a theoretical study of main flow effects for a spherical turret assembly for a Mach number (M) of 0.6. The second source is an actual wind tunnel density field measurement on a 0.3 scale laser turret/fairing assembly, with M = 0.75. A range of azimuthal angles from 0 to 90 deg was considered, while the elevation angle was always 0 deg (i.e., in the plane of the flow). The calculated optical path differences for these two markedly different geometries are of the same order. Scaling of results to sea level conditions and an aperture diameter of 50 cm indicated up to 0.0007 cm of phase variation across the aperture for certain forward look angles and a focal length of F = -11.1 km. These values are second order for a 10.6 micron system

New Experimental Results on Strangeness Production

New experimental results on the production of $\phi$ and $f_2'(1525)$ mesons in the annihilation of stopped antiprotons are discussed. The explanation of these facts in the framework of the polarized strangeness model is considered.Comment: 10 pages, Latex, fig1.eps, espcrc1.sty.
