Sgr A* ``Visual Binaries'': A Direct Measurement of the Galactocentric Distance

Samir Salim, Andrew Gould

We present a new geometrical method for measuring the distance to the Galactic center (R_0) by solving for the Keplerian orbit of individual stars bound to the black hole associate…

A Brief History of Star Formation and Chemical Enrichment in the Bulge of the Milky Way

Jay A. Frogel

Observations of the stellar content of the bulge of the Milky Way can provide critical guidelines for the interpretation of observations of distant galaxies, in particular for unde…

PU(2) monopoles and a conjecture of Marino, Moore, and Peradze

Paul M. N. Feehan, Peter B. Kronheimer, Thomas G. Leness +1

In this article we show that some of the recent results of Marino, Moore, and Peradze (math.DG/9812042, hep-th/9812055) -- in particular their conjecture that all closed, smooth fo…

Systematic Renormalization in Hamiltonian Light-Front Field Theory: The Massive Generalization

Roger D. Kylin, Brent H. Allen, Robert J. Perry

Hamiltonian light-front field theory can be used to solve for hadron states in QCD. To this end, a method has been developed for systematic renormalization of Hamiltonian light-fro…

Associated Production of Upsilon and Weak Gauge Bosons at the Tevatron

Eric Braaten, Sean Fleming, Jungil Lee

We calculate the rate of production of W+Upsilon and Z+Upsilon at the Tevatron. We find the cross sections at a center-of-mass energy of 1.8 TeV to be roughly 450 pb for W+Upsilon…

Magnetic field independence of the spin gap in YBa_2Cu_3O_{7-delta}

K. Gorny, O. M. Vyaselev, J. A. Martindale +8

We report, for magnetic fields of 0, 8.8, and 14.8 Tesla, measurements of the temperature dependent ^{63}Cu NMR spin lattice relaxation rate for near optimally doped YBa_2Cu_3O_{7-…
