Hard Single Diffraction in pbarp Collisions at root-s = 630 and 1800 GeV

The D0 Collaboration, B. Abbott

Using the D0 detector, we have studied events produced in proton-antiproton collisions that contain large forward regions with very little energy deposition (``rapidity gaps'') and…

An effective theory for omega << k << gT color dynamics in hot non-Abelian plasmas

Peter Arnold

A proper sequence of effective theories, corresponding to larger and larger distance scales, is crucial for analyzing real-time equilibrium physics in hot non-Abelian plasmas. For…

High temperature color conductivity at next-to-leading log order

Peter Arnold, Laurence G. Yaffe

The non-Abelian analog of electrical conductivity at high temperature has previously been known only at leading logarithmic order: that is, neglecting effects suppressed only by an…

Non-perturbative dynamics of hot non-Abelian gauge fields: beyond leading log approximation

Peter Arnold, Laurence G. Yaffe

Many aspects of high-temperature gauge theories, such as the electroweak baryon number violation rate, color conductivity, and the hard gluon damping rate, have previously been und…

RR Lyrae Stars in NGC 6388 and NGC 6441: A New Oosterhoff Group?

Barton Pritzl, Horace A. Smith, Marcio Catelan +1

NGC 6388 and NGC 6441 are anomalies among Galactic globular clusters in that they cannot be readily place into either Oosterhoff group I or Oosterhoff group II despite their signif…

Evolved Super Star Clusters in M82

R. de Grijs, R. W. O'Connell, J. S. Gallagher

We present high-resolution optical and near-infrared HST observations of two adjacent regions in the fossil starburst region in M82, B1 and B2. Age estimates date the cluster popul…
