Six dimensional phase space measurements at the SNS Beam Test Facility

Abstract:  This presentation covers the implementation and results from the first complete six-dimensional phase space measurement of a beam in a hadron accelerator. The measurement was made on the Spallation Neutron Source Beam Test Facility, a functional duplicate of the SNS front-end. The data reveal previously unknown correlations in the six-dimensional phase space distribution that are not visible in lower dimensionality measurements. These correlations are shown to be intensity dependent.

Thinking inside the box -- hadron resonances in quantum chromodynamics

Abstract:  The excited spectrum of hadrons is a spectrum of rapidly decaying resonances whose existence we infer from observations of their decay products. The underlying theory of quark and gluons, QCD, can be studied numerically using lattice techniques where the fields are considered on a grid of finite size. I will describe how we can make use of the finite box in which lattice QCD calculations are performed to learn something about hadron scattering amplitudes from first principles. These amplitudes contain information about the resonance structure of QCD and hence the spectrum of excited mesons and baryons. I will present the results of recent calculations in which the lightest scalar, vector and tensor mesons have been studied.
