Sterile neutrinos: propagation in matter and sensitivity to sterile mass ordering
Abstract We analytically calculate the neutrino conversion probability Pμe in the presence of sterile neutrinos, with exact dependence on %$ \Delta {m}_{41}^2 %$ and with matter effects explicitly included. Using perturbative expansion in small parameters, the terms involving the small mixing angles...

520 | |a Abstract We analytically calculate the neutrino conversion probability Pμe in the presence of sterile neutrinos, with exact dependence on %$ \Delta {m}_{41}^2 %$ and with matter effects explicitly included. Using perturbative expansion in small parameters, the terms involving the small mixing angles θ24 and θ34 can be separated out, with θ34 dependence only arising due to matter effects. We express Pμe in terms of the quantities of the form sin(x)/x, which helps in elucidating its dependence on matter effects and a wide range of %$ \Delta {m}_{41}^2 %$ values. Our analytic expressions allow us to predict the effects of the sign of %$ \Delta {m}_{41}^2 %$ at a long baseline experiment like DUNE. We numerically calculate the sensitivity of DUNE to the sterile mass ordering and find that this sensitivity can be significant in the range %$ \mid \Delta {m}_{41}^2\mid \sim \left({10}^{-4}-{10}^{-2}\right) %$ $ eV^{2} $, for either mass ordering of active neutrinos. The dependence of this sensitivity on the value of %$ \Delta {m}_{41}^2 %$ for all mass ordering combinations can be explained by investigating the resonance-like terms appearing due to the interplay between the sterile sector and matter effects. | ||

We numerically calculate the sensitivity of DUNE to the sterile mass ordering and find that this sensitivity can be significant in the range %$ \mid \Delta {m}_{41}^2\mid \sim \left({10}^{-4}-{10}^{-2}\right) %$ $ eV^{2} $, for either mass ordering of active neutrinos. The dependence of this sensitivity on the value of %$ \Delta {m}_{41}^2 %$ for all mass ordering combinations can be explained by investigating the resonance-like terms appearing due to the interplay between the sterile sector and matter effects.

Sterile neutrinos: propagation in matter and sensitivity to sterile mass ordering |
abstract |
Abstract We analytically calculate the neutrino conversion probability Pμe in the presence of sterile neutrinos, with exact dependence on %$ \Delta {m}_{41}^2 %$ and with matter effects explicitly included. Using perturbative expansion in small parameters, the terms involving the small mixing angles θ24 and θ34 can be separated out, with θ34 dependence only arising due to matter effects. We express Pμe in terms of the quantities of the form sin(x)/x, which helps in elucidating its dependence on matter effects and a wide range of %$ \Delta {m}_{41}^2 %$ values. Our analytic expressions allow us to predict the effects of the sign of %$ \Delta {m}_{41}^2 %$ at a long baseline experiment like DUNE. We numerically calculate the sensitivity of DUNE to the sterile mass ordering and find that this sensitivity can be significant in the range %$ \mid \Delta {m}_{41}^2\mid \sim \left({10}^{-4}-{10}^{-2}\right) %$ $ eV^{2} $, for either mass ordering of active neutrinos. The dependence of this sensitivity on the value of %$ \Delta {m}_{41}^2 %$ for all mass ordering combinations can be explained by investigating the resonance-like terms appearing due to the interplay between the sterile sector and matter effects. © The Author(s) 2023 |

Using perturbative expansion in small parameters, the terms involving the small mixing angles θ24 and θ34 can be separated out, with θ34 dependence only arising due to matter effects. We express Pμe in terms of the quantities of the form sin(x)/x, which helps in elucidating its dependence on matter effects and a wide range of %$ \Delta {m}_{41}^2 %$ values. Our analytic expressions allow us to predict the effects of the sign of %$ \Delta {m}_{41}^2 %$ at a long baseline experiment like DUNE. We numerically calculate the sensitivity of DUNE to the sterile mass ordering and find that this sensitivity can be significant in the range %$ \mid \Delta {m}_{41}^2\mid \sim \left({10}^{-4}-{10}^{-2}\right) %$ $ eV^{2} $, for either mass ordering of active neutrinos. The dependence of this sensitivity on the value of %$ \Delta {m}_{41}^2 %$ for all mass ordering combinations can be explained by investigating the resonance-like terms appearing due to the interplay between the sterile sector and matter effects.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Neutrino Mixing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sterile or Heavy Neutrinos</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Devi, Moon Moon</subfield><subfield code="0">(orcid)0000-0001-6569-0792</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dighe, Amol</subfield><subfield code="0">(orcid)0000-0001-6639-0951</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dutta, Debajyoti</subfield><subfield code="0">(orcid)0000-0002-8348-6098</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pramanik, Dipyaman</subfield><subfield code="0">(orcid)0000-0001-6589-3063</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Raut, Sushant K.</subfield><subfield code="0">(orcid)0000-0002-6401-1257</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of high energy physics</subfield><subfield code="d">Berlin : Springer, 1997</subfield><subfield code="g">2023(2023), 2 vom: 03.
