Constraints on the Nonstandard Interaction in Propagation from Atmospheric Neutrinos

Figure 2

Upper panel: the allowed region in the (, ) plane from the HK atmospheric neutrino data for a normal mass hierarchy (left panel) and for an inverted mass hierarchy (right panel) from the energy-rate analysis. Lower panel: the same allowed region as the upper panel from the two energy-bin analysis. Notice that the vertical scales in the lower panel are different for both mass hierarchies from the one in the upper panel.
