The axial Higgs position is revealed. A relative of the “Divine Particle” experimentally confirmed

An international team of physicists has discovered a new elementary particle, more precisely the so-called undetectable quantum excitation. The axial Higgs mode is the magnetic relativity of the Higgs boson.

The Higgs boson was discovered a decade ago, and we learn something new about this particle now and then. But we still don’t know everything yet. The axial Higgs mode has a magnetic moment, and this requires the use of more complex grounds. Described in temper nature.

Theories that predicted such a situation have been called upon to explain dark matter, the nearly undetectable matter that makes up most of the universe but only manifests itself through gravity.the professor. Kenneth Birch of Boston College, lead author of the study

To discover the axial Higgs mode, physicists had to focus on RTe3, or tritelluride of the rare earth metal, a well-known quantum substance. It has properties consistent with the theory of the axial Higgs mode. Physicists were able to overcome all difficulties thanks to the unique use of light scattering and the selection of a suitable quantum simulator. Professor’s team. Burcha focused on a compound long known to possess a “charge density wave,” a state in which electrons self-organize with a periodic density in space.

The basic theory of this wave mimics elements of the Standard Model of particle physics. In this case, the charge density wave is very particular, it appears well above room temperature and involves modulation of both the charge density and the atomic orbitals. As a result, the Higgs boson associated with this charge density wave may contain additional components, that is, it may be axial, which means that it has angular momentum.the professor.

Physicists have used the existence of the axial Higgs mode as an explanation for dark matter, but it has never been observed. The fairly simple experimental techniques the team uses can be applied to research other physics experiments.

Many of these experiments were done by a student in my lab. This approach can be readily applied to the study of quantum properties of many collective phenomena, including patterns in superconductors, magnets, ferroelectrics, and charge density waves. Moreover, we take the study of quantum interference in materials with correlated and/or topological phases to room temperature, to overcome the difficulties associated with harsh experimental conditions.the professor.
