Measurement of the muon neutrino inclusive charged-current cross section in the energy range of 1–3 GeV with the T2K INGRID detector
2016
International audience; We report a measurement of the $\nu_{\mu}$-nucleus inclusive charged current cross section (=$\sigma^{cc}$) on iron using 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$^\circ$ to 1.1$^\circ$. 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 $\sigma^{cc}(1.1\text{ GeV}) = 1.10 \pm 0.15$ $(10^{-38}\text{cm}^2/\text{nucleon})$, $\sigma^{cc}(2.0\text{ GeV}) = 2.07 \pm 0.27$ $(10^{-38}\te…
Transverse energy production and charged-particle multiplicity at midrapidity in various systems from √sNN = 7.7 to 200 GeV
2016
Measurements of midrapidity charged-particle multiplicity distributions, dNch/dη, and midrapidity transverseenergy distributions, dET /dη, are presented for a variety of collision systems and energies. Included are distributions for Au + Au collisions at √sNN = 200, 130, 62.4, 39, 27, 19.6, 14.5, and 7.7 GeV, Cu + Cu collisions at √sNN = 200 and 62.4 GeV, Cu + Au collisions at √sNN = 200 GeV, U + U collisions at √sNN = 193 GeV, d + Au collisions at √sNN = 200 GeV, 3 He + Au collisions at √sNN = 200 GeV, and p + p collisions at √sNN = 200 GeV. Centrality-dependent distributions at midrapidity are presented in terms of the number of nucleon participants, Npart, and the number of constituent q…
