… Previously, due to the limitations of the instruments, such effects couldn't be detected, but a new generation of spectroscopic experiments increases the achievable accuracy by several orders of magnitude, thus making these effects observable. This is an important contribution to science, confirming that generally accepted ideas should to be adjusted.
"If the King plot turns out to be slightly curved, this may be a manifestation of new particles beyond the Standard Model of physics. It is necessary to continue studying these effects in other atoms with a larger number of electrons in order to reduce the influence of calculation errors," said Vladimir Yerokhin, chief researcher at the Center for Advanced Studies of SPbPU. In the near future, the theoretical predictions obtained by scientists of St. Petersburg Polytechnic University will be verified experimentally at the Physikalisch Technische Bundesanstalt using the facilities which trap ions in the magnetic and electric fields and investigate them using the quantum logic methods. "If the experiment is successful, we can obtain restrictions on parameters of the proposed new particle beyond the Standard Model. In addition, such experiments will help to determine whether the fundamental constants change over time, which is of great importance for our understanding of the development of the Universe," commented Vladimir Yerokhin.
