Figure 1

Expected sensitivity to the electroweak mixing angle of a ${}^{51}\mathrm{Cr}$ neutrino source with the LENA detector. We show the result of a simulated ${\chi }^2$ analysis of the total number of events with a given total “error” of 0.5%, 1%, and 5% (left panel). We also show the expected precision at $1\sigma$ (68.27% CL) on ${sin}^2{\theta }_W$ as a function of a given percentual error (tilted line in right panel). Current NuTeV sensitivities associated to two evaluations of the systematical errors [10, 11] are also shown as horizontal lines.Reuse & Permissions

Figure 2

Expected sensitivity to the electroweak mixing angle of a ${}^{51}\mathrm{Cr}$ neutrino source with the LENA detector. We assume the data sample to be divided in seven bins of 50 keV each and an error per bin of 0.5%, 1%, and 5% (left panel). The expected precision (at 68.27% CL) of the ${sin}^2{\theta }_W$ determination as a function of the given error in percent is given by the tilted line on the right panel. Current NuTeV sensitivities are indicated by the two horizontal lines [10, 11].Reuse & Permissions

Figure 3

Left panel: Expected LENA sensitivity at 90% CL to nonuniversal NSI using a ${}^{51}\mathrm{Cr}$ neutrino source. The shaded areas correspond to a binned data sample divided in seven bins of 50 keV each and an error per bin of either 1% (grey inner region) or 5% (magenta outer region). For comparison, we show current limits to these parameters from an analysis coming from solar and KamLAND neutrino data [28] (dashed line) as well as from an analysis to the LEP and reactor data [29] (solid line). Right panel: Expected sensitivity at 90% CL to the mass of a new neutral gauge boson coupled to lepton number [18]. In both cases, we fix the weak mixing angle as ${sin}^2{\theta }_W=0.2313$.Reuse & Permissions
