EXPRESS: pH-Dependent Flavin Adenine Dinucleotide and Nicotinamide Adenine Dinucleotide Ultraviolet Resonance Raman (UVRR) Spectra at Intracellular Concentration

The ultraviolet resonance Raman (UVRR) spectra of the adenine-containing enzymatic redox cofactors nicotinamide adenine dinucleotide (NADH) and flavin adenine dinucleotide (FAD) in aqueous solution of physiological concentration are compared with the aim of distinguishing between them and their building block adenine in potential co-occurrence in biological materials. At an excitation wavelength of 266 nm, the spectra are dominated by the strong resonant contribution from adenine, nevertheless bands assigned to vibrational modes of the nicotinamide and the flavin unit are found to appear at similar signal strength. Comparison of spectra measured at pH 7 with data obtained pH 10 and pH 3 shows characteristic changes when pH is increased or lowered, mainly due to deprotonation of the flavin and nicotinamide moieties, and protonation of the adenine, respectively.

The recipe to search for anomalous Wtb couplings in tWb associated production process.

The impact of anomalous Wtb couplings on tWb process of the single top quark production has been probed in different schemes of tWb modeling. A special attention devotes to influence of the particular schemes to the anomalous couplings sensitivity. The distributions of representative variables demonstrate different behaviour in different simulation schemes, therefore the correct probe for anomalous Wtb couplings require specific approach to simulate BSM contribution. Special approach to search for BSM contribution in the off-shell tWb process is proposed in this paper. The approach is based on the kinematic separation of the double and single resonant contributions by means of neural network. The specific BSM properties are considered separately for the double and single resonant events. Such approach allows to add information on the anomalous Wtb coupling from simultaneous consideration of the tt¯ (double resonant) and tWb (off-shell, single resonant) contribution of tWb processes and therefore can improve the sensitivity to the anomalous Wtb couplings.

Higgs production through sterile neutrinos

In scenarios with sterile (right-handed) neutrinos with an approximate “lepton-number-like” symmetry, the heavy neutrinos (the mass eigenstates) can have masses around the electroweak scale and couple to the Higgs boson with, in principle, unsuppressed Yukawa couplings, while the smallness of the light neutrinos’ masses is guaranteed by the approximate symmetry. The on-shell production of the heavy neutrinos at lepton colliders, together with their subsequent decays into a light neutrino and a Higgs boson, constitutes a resonant contribution to the Higgs production mechanism. This resonant mono-Higgs production mechanism can contribute significantly to the mono-Higgs observables at future lepton colliders. A dedicated search for the heavy neutrinos in this channel exhibits sensitivities for the electron neutrino Yukawa coupling as small as [Formula: see text]. Furthermore, the sensitivity is enhanced for higher center-of-mass energies, when identical integrated luminosities are considered.

RPV SUSY effects in $\tau^- \to e^-(\mu^-) K\bar{K}$ decays

In this paper, we investigate [Formula: see text] decays in the framework of the RPV SUSY model. We discuss the tree-level contribution of the sparticles [Formula: see text] and [Formula: see text] to these decay branching ratios. In the two channels, the [Formula: see text]-mediated channel is more sensitive to the parameter product [Formula: see text] than the [Formula: see text]-mediated channel to [Formula: see text]. And the parameter product [Formula: see text] is severely constrained to the order of [Formula: see text] by the experiment data with [Formula: see text], which is one order of magnitude more stringent than before. In the calculation of hadronic matrix elements, the resonant effects are large than those of nonresonant terms. Especially, the resonant contribution of scalar meson f(980) plays a dominate role in [Formula: see text]-mediated channel.

AXIGLUON PHENOMENOLOGY USING ATLAS DIJET DATA

In recent years, there has been a renewed interest on axigluons as part of a possible extension of strong interactions at high energies. In this paper, we use recent ATLAS measurements of the dijet spectrum in order to set limits on the axigluon mass and coupling to quarks. We pay special attention to the methodology used to extract the resonant contribution from theoretical simulations. Finally, we present some predictions for the next LHC run at [Formula: see text].

EXTRACTING β AND THE NEW DSJ RESONANCES

The three body decays [Formula: see text], may be used to measure both sin 2β and cos 2β. Crucial to the cos 2β measurement is the resonant contribution to the three body decay from p-wave excited Ds, states. If these p-wave states are the newly discovered Ds(2317) and Ds(2460) then they are below the D(*)K threshold and hence do not contribute to [Formula: see text]. The three body decays can then be used to measure sin 2β without resonant dilution and to look for new physics in [Formula: see text] transition.

CROSS-SPECTRAL ANALYSIS OF TREMOR TIME SERIES

We discuss cross-spectral analysis and report applications for the investigation of human tremors. For the physiological tremor in healthy subjects, the analysis enables to determine the resonant contribution to the oscillation and allows to test for a contribution of reflexes to this tremor. Comparing the analysis of the relation between the tremor of both hands in normal subjects and subjects with a rare abnormal organization of certain neural pathways proves the involvement of central structures in enhanced physiological tremor. The relation between the left and the right side of the body in pathological tremor shows a specific difference between orthostatic and all other forms of tremor. An investigation of EEG and tremor in patients suffering from Parkinson's disease reveals the tremor-correlated cortical activity. Finally, the general issue of interpreting the results of methods designed for the analysis of bivariate processes when applied to multivariate processes is considered. We discuss and apply partial cross-spectral analysis in the frame of graphical models as an extention of bivariate cross-spectral analysis for the multivariate case.
