Anomalous single top quark production at the CERN LHC
(IOP Publishing, 2005-01)Production of single top quarks via the anomalous interaction u(c)g --> t, and its decay to W + b are studied for the CERN LHC ATLAS experiment. The sensitivity to anomalous coupling kappa/Lambda down to 0.024 TeV-1 can ... -
Temperature and time dependence of electrical and mechanical durability of LDPE/diamond composites
(Elsevier, 2006-03)In this study, the dependence of the electrical (tau(E)), mechanical (tau(sigma)) life time on electrical strength (E) and mechanical tension (sigma) of low density polyethylene composites with commercial diamond additive ... -
Observability of the Higgs boson in the presence of extra standard model families at the Tevatron
(Jagellonian University, 2006-11)The observability of the Higgs boson via the WW* decay channel at the Tevatron is discussed taking into account the enhancements due to the possible existence of the extra standard model (SM) families. It seems that the ... -
Comparison of optical properties and mechanical/electrical degradation of some low density polyethylene-and polypropylene-based polymer blends
(Springer, 2007)In this study, the optical properties as well as mechanical and electrical degradation of low-density polyethylene (LDPE)/polypropylene fiber (PP fiber) (10–50% PP fiber), polypropylene (PP)/PP fiber (10–50% PP fiber), and ... -
Simultaneous effect of mechanical tension on electrical lifetime of some inorganic composites
(World Scientific Publishing, 2007-09-10)In this work, the simultaneous effect of mechanical tension (sigma) and electrical strength (E) on electrical lifetime (TE) for pure low density polyethylene (LDPE)/polypropylene (PP) and composites with different commercial ... -
A new micromegas line for the CAST experiment
(Elsevier, 2007-10-21)A low background Micromegas detector has been operating on the Cern Axion Solar Telescope (CAST) experiment at CERN for the search of solar axions during the first phase of the experiment. The detector operated efficiently ... -
The ATLAS TRT electronics
(IOP Publishing, 2008)The ATLAS inner detector consists of three sub-systems: the pixel detector spanning the radius range 4cm-20cm, the semiconductor tracker at radii from 30 to 52 cm, and the transition radiation tracker (TRT), tracking from ... -
The ATLAS Transition Radiation Tracker (TRT) proportional drift tube: Design and performance
(IOP Publishing, 2008)A straw proportional counter is the basic element of the ATLAS Transition Radiation Tracker (TRT). Its detailed properties as well as the main properties of a few TRT operating gas mixtures are described. Particular attention ... -
The ATLAS TRT end-cap detectors
(IOP Publishing, 2008)The ATLAS TRT end-cap is a tracking drift chamber using 245,760 individual tubular drift tubes. It is a part of the TRT tracker which consist of the barrel and two end-caps. The TRT end-caps cover the forward and backward ... -
The ATLAS TRT barrel detector
(IOP Publishing, 2008)The ATLAS TRT barrel is a tracking drift chamber using 52,544 individual tubular drift tubes. It is one part of the ATLAS Inner Detector, which consists of three sub-systems: the pixel detector spanning the radius range 4 ... -
The ATLAS experiment at the CERN large hadron collider
(IOP Publishing, 2008)The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also ... -
Friedmann equation for brans-dicke cosmology
(World Scientific Publishing, 2008-02)In the context of the Brans-Dicke scalar tensor theory of gravitation, the cosmological Friedmann equation which relates the expansion rate H of the universe to the various fractions of energy density is analyzed rigorously. ... -
Chaotic inflation, radiative corrections and precision cosmology
(Elsevier, 2008-09)We employ chaotic (phi(2) and phi(4)) inflation to illustrate the important role radiative corrections can play during the inflationary phase. Yukawa interactions of phi, in particular, lead to corrections of the form -k ... -
On the constructive determination of spectral invariants of the periodic Schrodinger operator with smooth potentials
(IOP Publishing, 2008-09-12)In this paper, we develop the asymptotic formulae, obtained in my previous papers, for the band functions and the Bloch functions of the Schrodinger operator with the smooth periodic potentials. Then using these formulae, ... -
Probing eV-scale axions with CAST
(IOP Publishing, 2009-02)We have searched for solar axions or other pseudoscalar particles that couple to two photons by using the CERN Axion Solar Telescope (CAST) setup. Whereas we previously have reported results from CAST with evacuated magnet ... -
Can hyperbolic phase of Brans - Dicke field account for Dark Matter?
(World Scientific Publishing, 2009-04)We show that the introduction of a hyperbolic phase of the Brans-Dicke (BD) field results in a flat vacuum cosmological solution of the Hubble parameter H and a fractional rate of change of the BD scalar field F, which ... -
X - ray investigation of CdSe nanowires
(Wiley, 2009-08)CdSe nanowires (NWs) have been prepared by a solution-liquid-solid (SLS) approach using Bi nanocatalysts. Structural characterization has been performed by X-ray powder diffraction providing an admixture of wurtzite and ... -
Study of the response of the ATLAS central calorimeter to pions of energies from 3 to 9 GeV
(Elsevier, 2009-08)A fully instrumented slice of the ATLAS central detector was exposed to test beams from the SPS (Super Proton Synchrotron) at CERN in 2004. In this paper, the response of the central calorimeters to pions with energies in ... -
Pseudoscalar-meson decuplet-baryon coupling constants in light cone QCD
(American Physical Society, 2009-11)Taking into account the SU(3)(f) breaking effects, the strong coupling constants of the pi, K, and eta mesons with decuplet baryons are calculated within the light cone QCD sum rules method. It is shown that all coupling ... -
