We report a measurement of the νµ-nucleus inclusive charged current cross section (=σ cc) on ironusing data from exposed to the J-PARC neutrino beam. The detector consists of 14 modules in total, which are spread over a range of off-axis angles from 0◦ to 1.1◦. The variation in the neutrino energy spectrum as a function of the off-axis angle, combined with event topology information, is used to calculate this cross section as a function of neutrino energy. The cross section is measured to be σcc(1.1 GeV) = 1.10±0.15 (10^−38cm^2/nucleon), σcc(2.0 GeV) = 2.07±0.27 (10^−38cm^2/nucleon), and σcc(3.3 GeV) = 2.29 ± 0.45 (10^−38cm^2/nucleon), at energies of 1.1, 2.0, and 3.3 GeV, respectively. These results are consistent with the cross section calculated by the neutrino interaction generators currently used by T2K. More importantly, the method described here opens up a new way to determine the energy dependence of neutrino-nucleus cross sections.

In Europeanized policy domains, executive actors are considered especially powerful because they are directly responsible for international negotiations. However, in order to avoid failing in the ratification process, they are also highly dependent on the support of domestic, non-state actors. We argue that in Europeanized decision-making processes, state actors are not passively lobbied, but actively seek collaboration with - and support from - domestic actors. We apply stochastic actor-based modelling for network dynamics to collaboration data on two successive bilateral agreements on the free movement of persons between Switzerland and the European Union (EU). Results confirm our hypotheses that state actors are not passively lobbied, but actively look for collaboration with other actors, and especially with potential veto players and euro-sceptical actors from both the conservative Right and the Left.
