The Continuum

In the e+e- annihilation processes [Formula: see text], D+D- near or above the threshold of [Formula: see text], there are not only the resonance contribution [Formula: see text], D+D-, but also the continuum contribution through virtual photon directly [Formula: see text], D+D-. The amplitudes through virtual photon directly and through resonance can interfere seriously. We consider the continuum and interference effect in the [Formula: see text] production process in e+e- annihilation. We find that the effect is significant near and above the threshold of the [Formula: see text] mesons.

The Continuum

AbstractWe have been looking into the possibility to subtract out the continuum contribution in spectral line databases from the ungridded visibilities. It turns out that our simple method offers quite interesting possibilities in a lot of practical cases. In this contribution we show how and why this method works. Details of this work can be found in van Langevelde and Cotton (1990). We have tried to compare the results of this method with the mote conventional ways of subtracting the continuum. This comparison has to be done with simulations of which we show some results.

Ionization Nonequilibrium

We present the results of fitting an ionization nonequilibrium (NIE) model to the high energy (> 5 keV) X-ray spectra of the young supernova remnants Cas A and Tycho. As an additional constraint, we demand that the models simultaneously fit lower energy, higher resolution data. For Cas A, a single NIE component can not adequately reproduce the features for the entire X-ray spectrum because 1) the ionization structure of iron ions responsible for the K emission is inconsistent with that of the ions responsible for the lower energy lines, and 2) the flux of the highest energy X-rays is underestimated. The iron K line and the high energy continuum could arise from the same NIE component but the identification of this component with either the blast wave or the ejecta in the “standard” model is difficult. In Tycho, the high energy data rule out a class of models for the lower energy data which have too large a continuum contribution.

The Continuum

In this paper, we present preliminary results of the determination of the charm quark mass [Formula: see text] from QCD sum rules of moments of the vector current correlator calculated in perturbative QCD at [Formula: see text]. Self-consistency between two different sum rules allow to determine the continuum contribution to the moments without requiring experimental input, except for the charm resonances below the continuum threshold. The existing experimental data from the continuum region is used, then, to confront the theoretical determination and reassess the theoretic uncertainty.
