The weighted semigroup algebra Mb (S, w) is studied via its identification with Mb (S) together with a weighted algebra product *w so that (Mb (S, w), *) is isometrically isomorphic to (Mb (S), *w). This identification enables us to study the relation between regularity and amenability of Mb (S, w) and Mb (S), and improve some old results from discrete to general case.

We study the process WW → tt̄ in several models of strong interaction electroweak symmetry breaking. We calculate the signals that can be expected by observing the reaction ee→ νν̄tt̄ at an ee linear collider with 1.5 TeV center of mass energy. We also discuss how the lowest-lying resonances predicted by these models could be identified using top polarization observables. presented at the Internat...

We consider the reaction ee → WW mediated by possible heavy neutrino exchange at future LINAC energies of √ s >> 2mW . This reaction is sensitive to CP phases of the neutrino mixing matrices, even at the level of Born amplitudes. Certain integrated cross-sections are shown to have the power to resolve the CP phases when the experimental configurations are varied. Asymmetries sensitive to CP vio...

I present the calculation of the production of a W-boson pair in association with two jets at the Tevatron and LHC, performed to next-to-leading order in QCD. This is an important background in Higgs boson production, whether it occurs through gluon fusion or weak boson fusion. In this calculation, the W-bosons decay leptonically and all spin correlations are included. Although we find that the...

Effective quartic gauge couplings on tree level appear in a strong interacting Higgs scenario, which could be relevant, e.g. if no standard model Higgs would be found 1. This scenario can be described in terms of an effective chiral Lagrangian valid for invariant energies m W,Z < √ s < 4πv, where the vacuum expectation value due to electroweak symmetry breaking is v = (√ 2G F) −1 ≃ 246 GeV. It ...

Background: Since cannabis has been legally allowed for medicinal purposes in many countries, it has become more interesting issue, particularly in neurologic disorders such as Alzheimer’s disease (AD). Inhibition of acetylcholinesterase (AChE) is one of the mechanisms for the treatment of AD. Objectives: The present study aimed to establish a method for preparation of cannabinoids-rich extrac...
