Mass composition modelling at sources of ultra-high energy cosmic rays
Extragalactic sources are thought to be the origin of the highest energy cosmic rays detected at Earth. In this work, we explore energy-dependent mass compositions of these sources taking a...

Concept and Analysis for a 1 100 PeV Tau Neutrino Observatory
The IceCube Neutrino observatory has discovered an astrophysical neutrino flux in the energy range >>>1~TeV with their highest energy event ∼\sim∼3~PeV. Although IceCube has excellent muon flavor identification, their ability...

Resolving a challenging supersymmetric low-scale seesaw scenario at the ILC
We investigate a scenario inspired by natural supersymmetry, where neutrino data is explained within a low-scale seesaw scenario. For this the minimal supersymmetric Standard Model is extended by adding light...

Revealing the Majorana nature of neutrinos through a precision measurement of the CP phase
We show that it is possible to reveal the nature of neutrino by measuring the Majorana phase at the DUNE experiment. The Majorana phase is activated in the neutrino oscillation...

Setting limits on heavy neutral leptons using the neutrino CC events at the DUNE near detector
We study the impact of production of heavy neutral leptons (HNL) from meson decays on the number of neutrino charged current (CC) events that will be detected at the DUNE...
