If there is no the Standard Model Higgs boson, the interaction among the gauge bosons becomes strong at high energies (∼ 1TeV). The effects of strong electroweak symmetry breaking could manifest themselves indirectly through the vertices as anomalous gauge boson couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings κ...

We calculate the Coulomb effects on the cross section for e + e − → W + W − taking into account the instability of the W bosons. We carefully explain the consequences of instability throughout the energy range which will be accessible at LEP2. We present a formula which allows these effects to be easily implemented.

We study interference effects between resonant and nonresonant amplitudes for the γγ → W + W − process at a backscattered photon-photon collider. We show that a Higgs boson with M H > ∼ 200 GeV is manifest as a resonant dip in the W + W − invariant mass spectrum and we investigate its statistical significance. There has been recent interest in weak gauge boson pair production in γγ collisions a...

Professor W. Wallace Cleland, the architect of modern steady-state enzyme kinetics, died on March 6, 2013, from injuries sustained in a fall outside of his home. He will be most remembered for giving the enzyme community Ping-Pong kinetics and the invention of dithiothreitol (DTT). He pioneered the utilization of heavy atom isotope effects for the elucidation of the chemical mechanisms of enzym...

In a recent paper, the authors have shown that the secondary reduction of W-algebras provides a natural framework for the linearization of W-algebras. In particular, it allows in a very simple way the calculation of the linear algebra W(G, H) ≥0 associated to a wide class of W(G,H) algebras, as well as the expression of the W generators of W(G,H) in terms of the generators of W(G, H) ≥0. In thi...

Scan strategies for the measurement of--the e+e+ W+W-. threshold arg discussed. The most sensitive beam energies (I&) for the measurement of the T/lr mass (.k!w) and width (I?w are Eb N ik!tv + 0.5 GeV and Eb N &lw 1 GeV, ) respectively. With a commitment of 250 pb-’ to the measurement of the W-pa.ir threshold, it appears to be possible measure Mw with a precision SMw 2 160 MeV. The correspondi...

Objective(s) Theophylline, a xanthenes derivative, is still widely used as an effective bronchodilator in the management of asthmatic patients. It is used both as a prophylactic drug and to prevent acute exacerbations of asthma. The aim of study was to formulate and evaluate effect of the microencapsulation of theophylline loaded nanoparticles on the reduction of burst release. Materials and Me...
