Radial and orbital excitations of static-light mesons

We present results for the spectrum of static-light mesons from Nf=2 lattice QCD. These results were obtained using all-to-all light quark propagators on an anisotropic lattice, yielding an improved signal resolution when compared to more conventional lattice techniques. With a light quark mass close to the strange quark, we have measured the splittings between the ground-state S-wave static-light meson and higher excitations. We attempt to identify the quantum numbers of the excited states in the context of the reduced spatial symmetries of the lattice.Comment: 14 pages, 10 figure

Static-light mesons on a dynamical anisotropic lattice

We present results for the spectrum of static-light mesons from Nf=2 lattice QCD. These results were obtained using all-to-all light quark propagators on an anisotropic lattice, yielding an improved signal resolution when compared to more conventional lattice techniques. In particular, we consider the inversion of orbitally-excited multiplets with respect to the `standard ordering', which has been predicted by some quark models.Comment: 3 pages with 3 figures.

A perturbative determination of the parameters of an anisotropic quark action

The parameters of a 3+1 anisotropic quark action with Symanzik-improved glue are determined at 1-loop in perturbation theory.Comment: 3 pages, 2 figures. Talk presented at Lattice2004(improved), Fermilab, June 21-26, 200

Static-light matrix elements on a dynamical anisotropic lattice

The static-light matrix element needed to determine $f_B$ is studied on an anisotropic lattice with $N_f=2$. The improvement in precision due to stout links and all-to-all propagators is investigated.Comment: Lattice2004(heavy), Fermilab, June 21-26, 2004. 3 page

Static-light hadrons on a dynamical anisotropic lattice

We present preliminary results for the static-light meson and baryon spectra for $N_f=2$ QCD. The study is performed on an anisotropic lattice and uses a new all-to-all propagator method allowing us to determine particle masses to a high precision.Comment: 6 pages, Contribution to Lattice2005, PoS styl

How a County Utility Can Catalyze the 21st Century Economy: Cuyahoga County’s Vision to Develop Clean and Resilient Energy Districts to Attract and Retain Commercial Activity

The Cuyahoga County Department of Sustainability and the Cleveland State University Energy Policy Center have for the past several years been researching strategies for development of clean, highly resilient commercial districts in Cuyahoga County. In the fall of 2021, the County created a new utility division for the purpose of developing such districts, with the goal of attracting and retaining commercial activity. This paper summarizes the vision of the County as it moves forward with this innovative strategy to develop microgrids and other 21st century infrastructure that will attract business to the County

Phil Powers, Mike Foley, Harry Mushenheim: Marian Library Oral Histories

Kayla Harris interviewed Phil Powers, Mike Foley, and Harry Mushenheim on September 11, 2018 about their experiences as volunteers for the Marian Library. In this interview they discuss their work on the train set with University of Dayton engineering students, the community of volunteers from St. Luke’s Parish and hopes for the Marian Library in the future.https://ecommons.udayton.edu/ul_oral_histories/1000/thumbnail.jp

Mesons at high temperature in Nf=2 QCD

We report first results for spectral functions of charmonium in 2-flavour QCD. The spectral functions are determined from vector and pseudoscalar correlators on a dynamical, anisotropic lattice. J/psi and eta_c are found to survive well into the deconfined phase before melting away at T<~2T_c. Current systematic uncertainties prevent us from drawing any definite conclusions at this stage.Comment: 4 pages, 4 figures, to appear in proceedings of Computational Hadron Physics, Nicosia, 14-17 Sep 200
