Proton decay detection could put in evidence physics beyond the Standard Model (BSM). In this context, multiple projects are searching for such events. We focused our work on two of expected modes, $p \rightarrow \pi^+ + \bar{\nu}$ and K^+ \bar{\nu}$. Neutrinos particles that interact very weakly with matter, so they not interest work. The detector materials investigated study include liquid argon (LAr), xenon (LXe), water (H$_2$O). Our analysis focuses key effects relevant to process: Fermi...
A 10 kilo-tonne dual-phase liquid argon TPC is one of the detector options considered for Deep Underground Neutrino Experiment (DUNE). The technology relies on amplification ionisation charge in ultra-pure vapour and offers several advantages compared to traditional single-phase TPCs. 4.2 tonne prototype, largest its kind, with an active volume \three has been constructed operated at CERN. In this paper we describe detail experimental setup components as well report operation experience. We...
Recent work from the last years has raised possibility that a portion of Dark Matter could consist exotic particles, such as axion (anti)quark nuggets (AQN, A\bar{Q}N). After brief review outlining main features antiquark nuggets, we explore potential experimental signatures can be leveraged to search for these stable supermassive particles in future surface and underground experiments using large liquid detectors. These expected signals are discussed relation specific characteristics each...

The principal obstacle to long-time operation of silicon detectors at the highest energies in next generation experiments arises from bulk displacement damage which causes significant degradation their macroscopic properties. analysis behaviour after irradiation conduces a good or reasonable agreement between theoretical calculations and experimental data for time evolution leakage current effective carrier concentration lepton gamma large discrepancies hadron this conditions where is...
The feasibility of a next generation neutrino observatory in Europe is being considered within the LAGUNA design study. To accommodate giant detectors and shield them from cosmic rays, new very large underground infrastructure required. Seven potential candidate sites different parts at several distances CERN are studied: Boulby (UK), Canfranc (Spain), Fr\'ejus (France/Italy), Pyh\"asalmi (Finland), Polkowice-Sieroszowice (Poland), Slanic (Romania) Umbria (Italy). study aims comprehensive...
The nature of dark matter is still an open problem. simplest assumption that gravity the only force certainly coupled to and thus micro black holes could be a viable candidate. We investigated possibility direct detection charged with masses around upward Planck scale (10−5 g), ensuring classical gravitational treatment these objects in next generation huge LAr detectors. show signals (ionization scintillation) produced enable discrimination between other particles. It expected trajectories...
The influence of oxygen and carbon impurities on the concentrations defects in silicon for detector uses, complex fields radiation, characteristic to high energy physics experiments, is investigated frame quantitative phenomenological model developed previously by authors extended present paper. Continuous irradiation conditions are considered, simulating realistically environments these experiments. generation rate primary calculated starting from projectile–silicon interaction recoil...
Noble solid gases are promising detector materials to be used in the search for dark matter. In present paper a systematic analysis of transient phenomena associated with stopping recoils noble phase is performed first time.
