Is the X(3872) Production Cross Section at Tevatron Compatible with a Hadron Molecule Interpretation?

Phys.Rev.Lett. 103 (2009) 162001

by: Bignamini, C. (INFN, Pavia) et al.

Abstract:
The X(3872) is universally accepted to be an exotic hadron. In this letter we assume that the X(3872) is a D0 \bar D0* molecule, as claimed by many authors, and attempt an estimate of its prompt production cross section at Tevatron. A comparison with CDF data allows to draw some qualitative conclusions about this statement.

Monte Carlo tuning and generator validation

arXiv:0906.0075

by: Buckley, Andy (Durham U., IPPP) et al.

Abstract:
We present the Monte Carlo generator tuning strategy followed, and the tools developed, by the MCnet CEDAR project. We also present new tuning results for the Pythia 6.4 event generator which are based on event shape and hadronisation observables from e+e- experiments, and on underlying event and minimum bias data from the Tevatron. Our new tunes are compared to existing tunes and to Peter Skands' new 'Perugia' tunes.

Multi-jet cross sections at NLO with BlackHat and Sherpa

by: Berger, C.F. (MIT, LNS) et al.

Abstract:
In this talk, we report on a recent next-to-leading order QCD calculation of the production of a W boson in association with three jets at hadron colliders. The computation is performed by combining two programs, BlackHat for the computation of the virtual one-loop matrix elements and Sherpa for the real emission part.
