The recent data indicate that the neutrino mixing angle
θ
23
deviates from the maximal-mixing value of 45°, showing two nearly degenerate solutions, one in the lower octant (LO) (
θ

<

5
°
) and one in the higher octant (HO) (
θ
23
>
4
5
°
). We investigate, using numerical simulations, the prospects for determining the octant of
θ
23
in the future long baseline oscillation experiments. We present our results as contour plots on the (

δ
is the

phase, showing the true values of
θ
23
for which the octant can be experimentally determined at

confidence level. In particular, we study the impact of the possible nonunitarity of neutrino mixing on the experimental determination of
θ
23
in those experiments.

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment
DUNE Collaboration (Springer, 2021)The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a ... -
Omnibus experiment: CPT and CP violation with sterile neutrinos
Loo, Kai; Novikov, Yu. N.; Smirnov, M. V.; Trzaska, Wladyslaw; Wurm, M. (Institute of Physics Publishing, 2017)The verification of the sterile neutrino hypothesis and, if confirmed, the determination of the relevant oscillation parameters is one of the goals of the neutrino physics in near future. We propose to search for the sterile ... -
Numerical studies on neutrino oscillation physics in long baseline experiments
Vihonen, Sampsa (University of Jyväskylä, 2018)This thesis examines the prospects of future long baseline neutrino oscillation experiments. Using computer simulation techniques, we calculate the experimental sensitivities for two experimental configurations in a set of ... -
Effects of triplet Higgs bosons in long baseline neutrino experiments
Huitu, K.; Kärkkäinen, T. J.; Maalampi, Jukka; Vihonen, Sampsa (American Physical Society, 2018)The triplet scalars (Δ=Δ++, Δ+, Δ0) utilized in the so-called type-II seesaw model to explain the lightness of neutrinos, would generate nonstandard interactions (NSI) for a neutrino propagating in matter. We investigate ... -
Optimizing the θ23 octant search in long baseline neutrino experiments
Das, C.R.; Maalampi, Jukka; Pulido, J.; Vihonen, Sampsa (Institute of Physics Publishing, 2017)Determination of the θ 23 octant will be an important goal for the next generation of neutrino oscillation experiments, as it will show whether the true value of θ 23 lies in the high octant, θ 23 > 45°, or in the low ...
