The answer to the mystery of how the universe has not been scared because of anti-material may be in the bariss of the beauty-Lambda.
Scientists from CERN’s Great Hall (LHC) collusion have discovered an innovative clue to understand why the universe contains more matter than anti-material, preventing him from annihilating herself in nothing about millions of years. The discovery focuses on a asymmetry in the decomposition of particles known as bariums and their antimatter counterparts.
According to standard physical models, Big Bang should have produced equal amounts of matter and antimatter, leading to your mutual annihilation. However, our universe is full of matter, which suggests the existence of an unknown process that caused a slight imbalance. This phenomenon remains one of the greatest mysteries of physics.
Physicists have long been studying a concept called symmetry cargo-parity (CP), which postulates that the laws of physics should be identical for the particles and their mirrored anti-material twins.
However, previous experiences showed that CP symmetry is occasionally violated In certain types of particles, particularly in the mesons. Although these violations were intriguing, they were not enough to explain the survival of matter in relation to anti-material, reports.
Now, for the first time, the LHCB experience researchers have identified CP Violations in Baria – The family of particles that includes protons and neutrons, which constitute most observable matter. The findings have been subjected to Nature and are currently in a pre-review version of pairs in ARXIV.
The study focused on Beauty-Lambda Baries (Λb) and in their anti-material equivalents. By analyzing data from 2009 to 2018, scientists found a significant difference of 2.45% in the degradation rates of these particles, marking a definitive violation of CP with a statistical significance of 5.2 standard deviations.
“We needed a machine like the LHC, capable of producing a sufficiently large number of beauty bariums and anti-matter counterparts, and an experience that could accurately detect their degradation products,” said Vincenzo Vagnoni, LHCB collaboration spokesman. “It took more than 80,000 degrading of baron to make this observation.”
This discovery suggests that previously unknown physical forces or particles may be influence interactions between matter and anti-material. If confirmed, you can help refine the standard model of particle physics and open doors to the discovery of new physics beyond current theoretical frames.
