Generation of a typical meteorological year using sunshine duration data
(Elsevier BV, 2002-10)
Combined performance tests before installation of the ATLAS Semiconductor and Transition Radiation Tracking Detectors
(IOP Publishing, 2008-8-8)
The ATLAS (A Toroidal LHC ApparatuS) Inner Detector provides charged particle tracking in the centre of the ATLAS experiment at the Large Hadron Collider (LHC). The Inner Detector consists of three subdetectors: the Pixel ...
Exclusive Λb→Λℓ+ℓ− decay beyond standard model
(Elsevier BV, 2003-1)
Using the most general, model independent form of the effective Hamiltonian, the exclusive rare baryonic Λb→Λℓ+ℓ−(ℓ=μ,τ) decay is analyzed. We study the sensitivity of the branching ratio and lepton forward–backward asymmetry ...
Analysis of the Raman frequencies of a lattice mode in NH4Cl close to the tricritical and second order phase transitions
(Elsevier BV, 2006-4)
We analyze here our observed Raman frequencies of the nu(5) (174 cm(-1)) mode in NH4Cl close to its tricritical (P = 1.6 kbar) and the second order (P = 2.8 kbar) phase transitions. The critical behavior of the frequency ...
Gödel-type metrics in various dimensions
(IOP Publishing, 2005-4-6)
Godel-type metrics are introduced and used in producing charged dust solutions in various dimensions. The key ingredient is a (D-1)-dimensional Riemannian geometry which is then employed in constructing solutions to the ...
Mechanisms of void formation in Ge implanted SiO2 films
(Elsevier BV, 2003-8)
The present paper reports on annealing of Ge implanted SiO2 films and emphasize the observation of voids and the mechanism behind their formation which is considered new. Samples were prepared by ion implanting fluences ...
Intersubband resonant enhancement of the nonlinear optical properties in compositionally asymmetric and interdiffused quantum wells
(AIP Publishing, 2008-5-15)
We report the resonant enhancement of the second- and third-order optical nonlinearities in compositionally asymmetric quantum wells with finite confining potential and interdiffused quantum wells. The energy levels and ...
Donor–acceptor pair recombination in gallium sulfide
(AIP Publishing, 2000-12-15)
Low temperature photoluminescence of GaS single crystals shows three broad emission bands below 2.4 eV. Temperature and excitation light intensity dependencies of these bands reveal that all of them originate from close ...
Lepton flavor violatingZ→l1+l2−decay in the general two Higgs doublet model
(American Physical Society (APS), 2001-11-28)
We calculate lepton flavor violating Z-->l(1)(+)l(2)(-) decay in the framework of the general two Higgs doublet model. In our calculations we use the constraints for the Yukawa couplings (xi) over bar (D)(N,taue) and (xi) ...
Recent torque reversal of 4U 1907+09
(Oxford University Press (OUP), 2009-5-11)
We present timing and spectral analysis of RXTE-PCA ( Proportional Counter Array) observations of the accretion powered pulsar 4U 1907+09 between 2007 June and 2008 August. 4U 1907+09 had been in a spin-down episode with ...
