Search for an excess of events with an identical flavour lepton pair and significant missing transverse momentum in root s=7 TeV proton-proton collis…

2011

Results are presented of a search for supersymmetric particles decaying into final states with significant missing transverse momentum and exactly two identical flavour leptons (e or mu) of opposite charge in sqrt{s}=7 TeV collisions at the Large Hadron Collider. This channel is particularly sensitive to supersymmetric particle cascade decays producing flavour correlated lepton pairs. Flavour uncorrelated backgrounds are subtracted using a sample of opposite flavour lepton pair events. Observation of an excess beyond Standard Model expectations following this subtraction procedure would offer one of the best routes to measuring the masses of supersymmetric particles. In a data sample corres…

Ordered structures of DNA on Au(110)

2008

Reflection Anisotropy Spectroscopy (RAS) is used to confirm that both single stranded (ss) and double stranded (ds) DNA formed ordered structures when adsorbed at Au(110)/phosphate buffer interface. The variation of the spectral intensity shows a cos 2θ dependence on the angle θ, which lies between the electric vector of the incident polarised light and the optical axes of the surface plane of the Au(110) establishing that the optical axes of both molecules are aligned with those of the Au(110) surface.

Reflection anisotropy spectroscopy of decanethiol adsorbed at Au(110)/liquid interfaces

2008

Reflection Anisotropy Spectroscopy (RAS) has been used to monitor the adsorption of decanethiol as a function of coverage on the Au(110)/ethanol interface. The coverage saturates after 60 minutes for a solution of 0.5 µM. It is found that the RAS observed after 30 minutes can be represented as a linear sum of the RAS observed after 15 minutes and after saturation coverage. This implies that the molecule does not change its orientation as function of coverage. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
