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 the prospects to probe these interactions in long baseline neutrino oscillation experiments. We analyze the upper bounds that the proposed DUNE experiment might set on the nonstandard parameters and numerically derive upper bounds, as a function of the lightest neutrino mass, on the ratio the mass

. We also discuss the possible misinterpretation of these effects as effects arising from a nonunitarity of the neutrino mixing matrix and compare the results with the bounds that arise from the charged lepton flavor violating processes.

Novel mechanism for primordial perturbations in minimal extensions of the Standard Model
Karam, Alexandros; Markkanen, Tommi; Marzola, Luca; Nurmi, Sami; Raidal, Martti; Rajantie, Arttu (Springer, 2020)We demonstrate that light spectator fields in their equilibrium can source sizeable CMB anisotropies through modulated reheating even in the absence of direct couplings to the inflaton. The effect arises when the phase ... -
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 ... -
Long-baseline neutrino oscillation physics potential of the DUNE experiment
DUNE Collaboration (Springer, 2020)The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and ... -
Low exposure long-baseline neutrino oscillation sensitivity of the DUNE experiment
DUNE Collaboration (American Physical Society (APS), 2022)The Deep Underground Neutrino Experiment (DUNE) will produce world-leading neutrino oscillation measurements over the lifetime of the experiment. In this work, we explore DUNE’s sensitivity to observe charge-parity violation ... -
Determination of the θ23 octant in long baseline neutrino experiments within and beyond the standard model
Das, C. R.; Pulido, João; Maalampi, Jukka; Vihonen, Sampsa (American Physical Society, 2018)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 23 < 4 5 ° ) and one in the ...
