The direct detection of dark matter constituents, in particular the weakly interacting massive particles (WIMPs), is central to particle physics and cosmology. In this paper we study WIMP induced transitions from isomeric nuclear states for two possible candidates: Ta180 Ho166. experimental setup, which can measure decay by WIMPs, was proposed. corresponding estimates half-life are given sense that WIMP-nucleon interaction be interpreted as ordinary radioactive decay.
LENA (Low Energy Neutrino Astronomy) is a proposed next-generation neutrino detector based on 50 kilotons of liquid scintillator. The low detection threshold, good energy resolution and excellent background rejection inherent to the liquid-scintillator detectors make versatile observatory for low-energy neutrinos from astrophysical terrestrial sources. In framework European LAGUNA-LBNO design study, also considered as far very-long baseline beam CERN Pyhäsalmi (Finland). present contribution...
The investigation of the oscillation pattern induced by sterile neutrinos might determine parameters, and at same time, allow to probe CPT symmetry in leptonic sector through neutrino–antineutrino mass inequality. We propose use a large scintillation detector like JUNO or LENA detect electron antineutrinos from MCi capture beta decay sources. Our calculations indicate that such an experiment is realistic could be performed parallel current research plans for RENO. Requiring least 5σ...
The existence of sterile neutrino is an open question in physics up to now. method oscillometry provides a powerful tool test the common 3+1 hypothesis, i.e. three active flavors and one falvor. There are several antineutrino sources can be used for this method. One them well known isotope chain $^{144}{\rm Ce}-$$^{144}{\rm Pr}$ with initial activity around 50-100 kCi. It has compact size might installed either outside or inside detector. Another short-lived $\rm^8Li$, which produced nuclear...

Neutrino-antineutrino conversion is an important new physics process. The observation of this phenomenon could indicate total lepton number violation and potential CPT-violation. Searching for the appearance electron antineutrinos from solar neutrinos B8 decay allows us to hunt rare process, although it can also be explained by other mechanisms or hypotheses. This analysis examines capabilities observing neutrino-antineutrino transition unoscillated using different liquid scintillator...

In this paper we study the Target Set Selection problem (TSS) – well-known combinatorial associated with collective behaviour in networks. For a given network graph and information diffusion model that specifies dynamic process of how vertices activate each other, TSS aims to identify set initially active minimum cardinality such they manage all other vertices. This is computationally hard but has numerous applications practice, thus development computational algorithms for relevant topic. A...
This research continues to focus on the idea using cyclotronic antineutrino source for purposes of neutrino physics. Long baseline experiments suffer from degeneracies and correlations between $\Theta_{23}$, $\delta_{\rm CP}$ mass hierarchy (MH). However combination a superconductive cyclotron big liquid scintillator detector like JUNO in medium experiment, which does not depend MH, may allow us determine whether position mixing angle $\Theta_{23}$ is lower octant (LO) or upper (UO). Such an...
