Not like HiggsFound in the Large Hadron Collider of the European Organization for Nuclear Research (CERN) in 2012, theoretical physicists from the University of Granada and Johannes Gutenberg University in Germany proposed the existence of such heavy particles that Cannot be directly generated in this experiment. This may be opening the mysterious window of dark matter.
Scientist from University of Granada (UGR) And Johannes Gutenberg University of Mainz (Germany) just published in European Journal of Physics C They try to expand the scope of research Standard Model of Particle Physics And answer some unexplainable unknowns: what is Dark matter, Because different components of matter or fermions have different masses, or why gravity is much weaker than electromagnetic interaction.
One of the authors explained that this work is based on a small spatial dimension, “it is too small, and we can only prove it through its indirect influence.” Adrian Carmona, Member of UGR Theory and Cosmophysics Department, Athenea3i researcher.
As early as the 1920s, in order to unify gravity and electromagnetic force, Theodor Kaluza and Oskar Klein speculated that they existed Extra dimension Beyond the three space-times, this is physically combined in the four space-times.
These models became popular in the 1990s, when theoretical physicists realized that theories with extra dimensions of bending could explain some of the most important problems in the field.However, although these models have many advantages, they usually lack Viable dark matter candidates.
Now, more than 20 years later, Carmona predicts the existence of these models together with Professor Matthias Neubert and PhD student Javier Castellano of the German University A new heavy particle with properties similar to the famous Higgs boson.
“The particle may be Mass generation All particles sensitive to this extra dimension are at the same time the only relevant window Possible dark areas The reasons leading to the existence of dark matter will solve the two biggest problems in these prior incoherent theories in one fell swoop,” Carmona explained.
However, unlike the Higgs boson, the Higgs boson is Large Hadron Collider or Large Hadron Collider European Particle Physics Laboratory (European Organization for Nuclear ResearchAfter more than 40 years of searching, in 2012, the particles proposed by these researchers were so heavy that they could not be directly produced in this experiment. This is the world’s most energetic collider.
In this article, the author puts forward the equations and studies other possible ways of discovering such particles, trying to get clues about physics from the early stages of the universe’s history (when dark matter was produced).
