Dark-OsT Report Summary

Project ID: 695405
Funded under: H2020-EU.1.1.

Periodic Reporting for period 1 - Dark-OsT (Experimental Searches for Oscillating and Transient effects from the Dark Sector)

Reporting period: 2016-08-01 to 2018-01-31

Summary of the context and overall objectives of the project

The Dark-OST project aims to search for ultralight cosmic particles that are hypothesized to be the constituent of Dark Matter, the dominant yet elusive part of the matter in our Universe. Discovering such particles will also help answer other important questions in modern science, including: What is the reason of the observed predominance of matter over antimatter in the Universe? What is the mechanism of the CP violation? Why are all observed elementary particles so light compared to the fundamental energy scales (the grand-unification scale and the Planck scale)?

Understanding of the most fundamental laws of nature is a high intellectual pursuit that has led to revolutionary technological advances along the way. In Dark-OST, we are developing novel magnetic-resonance technologies that will be useful in applications to chemistry and biology, apart from advancing fundamental science.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

As part of the Dark-OST project, we have developed and implemented new hardware and data analysis techniques for the CASPEr and GNOME experiments, have collected experimental data, and are currently in the process of writing several papers reporting on the results. Several paper on the development of the apparatus and the associated techniques have been published during the reporting period.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

Until the end of the project, we anticipate to complete and publish the results from three experimental runs of the GNOME experiment, the first stage of the CASPEr-E experiment (with magnetic fields up to 7 T), as well as complete and publish the experiments with the CASPEr-ZULF (zero-and ultralow-field) setup using parahydrogen-hyperpolarized nuclei, significantly cutting into the currently unexplored parameter space for axions and axion-like particles (ALPs).
