Production of a W boson and two jets with one b-quark tag
J. Campbell, R. K. Ellis, F. Maltoni +1
The production of a W boson and two jets, at least one of which contains a b quark, is a principal background to single-top production, Higgs production, and signals of new physics…
Anomalous enhancement of a penguin hadronic matrix element in B->K eta'
J. -M. Gerard, E. Kou
We estimate the density matrix element for the pi^0, eta and eta' production from the vacuum in the large-N_c limit. As a consequence, we find that the QCD axial anomaly leads to h…
The unit of electric charge and the mass hierarchy of heavy particles
G. Lopez Castro, J. Pestieau
We propose some empirical formulae relating the masses of the heaviest particles in the standard model (the W,Z,H bosons and the t quark) to the charge of the positron and the…
A standard format for Les Houches Event Files
J. Alwall, A. Ballestrero, P. Bartalini +32
A standard file format is proposed to store process and event information, primarily output from parton-level event generators for further use by general-purpose ones. The informat…
