Line Shapes of the Z(4430)
Eric Braaten, Meng Lu
The Belle Collaboration recently discovered the first manifestly exotic meson: Z^+(4430), which decays into psi' pi^+ and therefore has quark content c c-bar u d-bar. The proximity…
Universality in Few-Body Systems
Lucas Platter
Low-energy universality in atomic few-body systems as a result of a large two-body scattering length has gained a lot of attention recently. Here, I discuss recent progress in desc…
Where Centaurus A gets its X-ray knottiness
D. M. Worrall, M. Birkinshaw, R. P. Kraft +15
We report an X-ray spectral study of the transverse structure of the Centaurus A jet using new data from the Chandra Cen A Very Large Project. We find that the spectrum steepens wi…
A Measurement of the Branching Fractions of exclusive Bbar -> D(*)(pi)l-nubar Decays in Events with a Fully Reconstructed B Meson
The BABAR Collaboration, B. Aubert
We report a measurement of the branching fractions for Bbar -> D(*)(pi)l-nubar decays based on 341.1 fb-1 of data collected at the Upsilon(4S) resonance with the babar detector at…
Time-dependent Dalitz plot analysis of B0 -> D-(+) K0 Pi+(-) decays
The BABAR Collaboration, B. Aubert
We present for the first time a measurement of the weak phase 2b+g obtained from a time-dependent Dalitz plot analysis of B^0 -> D-(+) K0 Pi+(-) decays. Using a sample of approxima…
The center of some braid groups and the Farrell cohomology of certain pure mapping class groups
Yu Qing Chen, Henry H. Glover, Craig A. Jensen
In this paper we first show that many braid groups of low genus surfaces have their centers as direct factors. We then give a description of centralizers and normalizers of prime o…
