Determination of the strong coupling constant from the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV

D0 Collaboration, V. M. Abazov

We determine the strong coupling constant alphas and its energy dependence from the pT dependence of the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV. The st…

Droplet-like Fermi surfaces in the anti-ferromagnetic phase of EuFe $_{2}$ As $_{2}$ , an Fe-pnictide superconductor parent compound

S. de Jong, E. van Heumen, S. Thirupathaiah +15

Using angle resolved photoemission it is shown that the low lying electronic states of the iron pnictide parent compound EuFe $_{2}$ As $_{2}$ are strongly modified in the magnetically or…

A Search for B+ -> tau+ nu Recoiling Against B- -> D0 l- nu X

The BABAR Collaboration, B. Aubert

We present a search for the decay $B^{+} \to ℓ^{+} ν_{ℓ}$ ( $ℓ = e, μτ$ ) in $(458.9 \pm 5.1) \times 1 0^{6}$ $B B ˉ$ pairs recorded with the BABAR detector at the PEP-II B-Facto…

Determination of the S-wave pi pi scattering lengths from a study of K+- -> pi+- pi0 pi0 decays

2 Collaboration

We report the results from a study of the full sample of ~ 6.031 10^7 K+- -> pi+- pi0 pi0 decays recorded by the NA48/2 experiment at the CERN SPS. As first observed in this experi…

Soliton Staircases and Standing Strain Waves in Confined Colloidal Crystals

Yu-Hang Chui, Surajit Sengupta, Kurt Binder

We show by computer simulation of a two-dimensional crystal confined by corrugated walls that confinement can be used to impose a controllable mesoscopic superstructure of predomin…
