Comments on the reach of INO experiment: JHEP 1304, 009 (2013) and arXiv:1303.2534 [hep-ph]

Abstract

In JHEP {\bf 1304}, 009 (2013) and arXiv:1303.2534 [hep-ph] the {\it reach of INO experiment} for determination of neutrino mass hierarchy and the sensitivity to both $\Delta m_{32}^2$ and ${\theta }_{23}$ have been reported, which are significantly underestimated and drastically different from earlier studies JHEP {\bf 1107}, 048 (2011), Phys. Rev. D {\bf 81}, 037302 (2010) and strongly dependent on the flux uncertainties. Here, we clarified that the effect on oscillation probability due to change of oscillation parameters are not considered appropriately due to improper binning of data, improper incorporation of resolutions, and rejection of high energy events $E\text{gapp}$ 10 GeV.
