And researchers from University of Sussex, United Kingdom, announced Wednesday they had "disproved the existence of a specific type of axion
Working on the similar lines of conventional cavity-based light dark matter experiments, we propose here a modified experiment and the associated detection scheme involving a new detector design, with a hope that it might offer a valuable detection strategy for the postulated Skivie axions
in the prescribed axion
Together with Gabriela Mocanu he calculated at the Vienna University of Technology (Institute for Theoretical Physics), how axions
could be detected.
Igor Garcia Irastorza, deputy spokesperson for CAST, said in (https://home.cern/about/updates/2017/05/cern-casts-new-limits-dark-matter) the statement : "The limits concern a part of the axion
parameter space that is still favoured by current theoretical predictions and is very difficult to explore experimentally.
Zhang and his colleagues described an experimental set-up that could detect for the first time the axion
, a theoretical tiny, lightweight particle conjectured to permeate the universe.
sprang from an attempt to explain certain differences between the strong and weak nuclear forces.
In a multiverse, each universe will have a random value for the axion
's misalignment angle, giving some universes the right amount of dark matter needed to give rise to galaxies, stars, planets and life as we know it.
In the latest study, a team of researchers from the Perimeter Institute for Theoretical Physics, the Stanford Institute for Theoretical Physics, and the Center for Cosmology and Particle Physics at New York University argue that if these hypothetical particles have the predicted mass, spinning and colliding black holes should produce a cloud of axions
- much like the cloud of electrons around an atom's nucleus - due to a phenomenon known as superradiance.
This means that every cubic centimetre of the universe should contain an average of 10 million axions
, and regions having larger concentration of dark matter, such as our local region of the Milky Way, should contain roughly 1 trillion axions
per cubic centimetre.
