    Vbfnlo is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), double and triple vector boson (plus jet) production in hadronic collisions at next-to-leading order (NLO) in the strong coupling constant, as well as Higgs boson plus two jet production via gluon fusion at the one-loop level. This note briefly describes the main additional features and processes that have been added in the new release -- Vbfnlo Version 2.6.0. At NLO QCD diboson production (W\gamma, WZ, ZZ, Z\gamma and \gamma\gamma), same-sign W pair production via vector boson fusion and the process W\gamma\gamma j have been implemented (for which one-loop tensor integrals up to six-point functions are included). In addition, gluon induced diboson production can be studied separately at the leading order (one-loop) level. The diboson processes WW, WZ and W\gamma can be run with anomalous gauge boson couplings, and anomalous couplings between a Higgs and a pair of gauge bosons is included in WW, ZZ, Z\gamma and \gamma\gamma diboson production. The code has also been extended to include anomalous gauge boson couplings for single vector boson production via VBF, and a spin-2 model has been implemented for diboson pair production via vector boson fusion.Comment: 14 pages, 6 tables; new code available at http://www-itp.particle.uni-karlsruhe.de/vbfnlo

    The Nation, Europe and the World: Textbooks and Curricula in Transition

    No full text
    Textbooks in history, geography and the social sciences provide important insights into the ways in which nation-states project themselves. Based on case studies of France, Germany, the Netherlands, Spain, Greece, Turkey Bulgaria, Russia, and the United States, this volume shows the role that concepts of space and time play in the narration of ?our country? and the wider world in which it is located. It explores ways in which in western European countries the nation is reinterpreted through European lenses to replace national approaches in the writing of history. On the other hand, in an effort to overcome Eurocentric views,?world history? has gained prominence in the United States. Yet again, East European countries, coming recently out of a transnational political union, have their own issues with the concept of nation to contend with. These recent developments in the field of textbooks and curricula open up new and fascinating perspectives on the changing patterns of the re-positioning process of nation-states in West as well as Eastern Europe and the United States in an age of growing importance of transnational organizations and globalization
