Search for anomalous top quark couplings with the D0 detector

D0 Collaboration, V. Abazov

Anomalous Wtb couplings modify the angular correlations of the top quark decay products and change the single top quark production cross section. We present limits on anomalous top…

Emergence of Spontaneous Order Through Neighborhood Formation in Peer-to-Peer Recommender Systems

Ernesto Diaz-Aviles, Lars Schmidt-Thieme, Cai-Nicolas Ziegler

The advent of the Semantic Web necessitates paradigm shifts away from centralized client/server architectures towards decentralization and peer-to-peer computation, making the exis…

Measurement of D+- and D0 production in deep inelastic scattering using a lifetime tag at HERA

ZEUS Collaboration, S. Chekanov

The production of D+- and D0 mesons has been measured with the ZEUS detector at HERA using an integrated luminosity of 133.6 pb-1. The measurements cover the kinematic range 5 < Q^…

Subjet distributions in deep inelastic scattering at HERA

ZEUS Collaboration, S. Chekanov

Subjet distributions were measured in neutral current deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 81.7 pb-1. Jets were identified…

The structure of surfaces and threefolds mapping to the moduli stack of canonically polarized varieties

Stefan Kebekus, Sandor J. Kovacs

Generalizing the well-known Shafarevich hyperbolicity conjecture, it has been conjectured by Viehweg that a quasi-projective manifold that admits a generically finite morphism to t…

Formation of ultracold dipolar molecules in the lowest vibrational levels by photoassociation

J. Deiglmayr, M. Repp, A. Grochola +6

We recently reported the formation of ultracold LiCs molecules in the rovibrational ground state X1Sigma+,v''=0,J''=0 [J. Deiglmayr et al., PRL 101, 133004 (2008)]. Here we discuss…
