Physicists at CERN Confirm Einstein’s Special Relativity Holds True for Top Quarks
Physicists with the CMS Collaboration at CERN’s Large Hadron Collider (LHC) have conducted groundbreaking research to test whether top quarks adhere to Albert Einstein’s special theory of relativity. Their findings,published in the October 2024 issue of Physics Letters B,reaffirm the validity of Einstein’s century-old theory,even at the extreme energies of the LHC.
At the core of this study is the concept of Lorentz symmetry, a fundamental principle of special relativity. It states that experimental results are independent of the orientation or speed of the experiment. While special relativity has withstood decades of scrutiny, some theories, including certain string theory models, predict that at very high energies, Lorentz symmetry could break down. This would mean experimental observations could depend on the orientation of the experiment in space-time.
“In this case, a dependence on the orientation of the experiment would mean that the rate at which top-quark pairs are produced in proton-proton collisions at the LHC would vary with time,” explained the researchers. “More precisely, since Earth rotates around its axis, the direction of the LHC proton beams and the average direction of top quarks produced in collisions at the centre of the CMS experiment also change depending on the time of the day.”
The team analyzed data from the second run of the LHC, focusing on the production rate of top-quark pairs. If Lorentz symmetry were broken, this rate would fluctuate with the Earth’s rotation, revealing a preferential direction in space-time. Tho, the results showed a constant rate, confirming that Lorentz symmetry remains intact and Einstein’s special relativity continues to hold true.
“Hence, finding a deviation from a constant rate would amount to discovering a preferential direction in space-time,” the scientists noted.
The study also set stringent limits on parameters predicted to be null if Lorentz symmetry holds. These limits improve by up to a factor of 100 compared to previous searches at the Tevatron accelerator.
“The results pave the way for future searches for Lorentz symmetry breaking based on top-quark data from the third run of the LHC,” the researchers added.
This research not only reinforces the robustness of Einstein’s theory but also opens new avenues for exploring the boundaries of modern physics.

In a groundbreaking study published in Physics Letters B, physicists at CERN’s CMS Collaboration have confirmed that Albert Einstein’s special theory of relativity holds true even at the extreme energies of the Large Hadron Collider (LHC). This research, centered on the behaviour of top quarks, tested the fundamental principle of lorentz symmetry, wich underlies Einstein’s theory. we sat down with Dr. Maria Gonzalez, a leading physicist and expert in particle physics, too discuss the implications of this remarkable revelation.
The Experiment: Testing Lorentz Symmetry with Top Quarks
Senior Editor: Dr. Gonzalez, can you start by explaining the core objective of this experiment and why top quarks were chosen as the focus?
Dr. Maria Gonzalez: Absolutely. The goal was to test whether Lorentz symmetry, a cornerstone of Einstein’s special relativity, holds true at the high-energy conditions of the LHC. Top quarks are ideal for this as they are the heaviest known fundamental particles, making them sensitive to potential deviations from relativity at extreme scales. By analyzing the production rate of top-quark pairs during proton-proton collisions, we could probe whether space-time behaves differently at thes energies.
The Role of Earth’s Rotation in the Study
Senior Editor: The study mentions that the rate of top-quark pair production could vary with Earth’s rotation if Lorentz symmetry were broken. Can you elaborate on how this was measured?
Dr. Maria Gonzalez: Certainly. If Lorentz symmetry were violated, the universe woudl have a preferential direction in space-time. Since the Earth rotates, the orientation of the LHC’s proton beams changes relative to this hypothetical preferred direction. This would cause the rate of top-quark pair production to fluctuate over time. We analyzed data from the LHC’s second run and found the rate remained constant, ruling out any such preferred direction and confirming Lorentz symmetry.
Implications for Modern Physics
Senior Editor: What does this mean for theories like string theory that predict Lorentz symmetry breaking at high energies?
Dr. Maria Gonzalez: This study sets stringent limits on the parameters that would indicate Lorentz symmetry breaking, improving on previous searches by up to a factor of 100. While some string theory models suggest such deviations could occur, our results provide no evidence for them. This reinforces the validity of Einstein’s relativity and narrows the scope for alternative theories that predict symmetry violations.
Future Research at the LHC
Senior Editor: How does this study pave the way for future experiments at the LHC?
Dr. Maria Gonzalez: This research lays a strong foundation for future investigations during the LHC’s third run. With more data, we can further refine our understanding of Lorentz symmetry and search for even subtler deviations. It also opens new avenues for exploring the fundamental nature of space-time and the behavior of particles at the highest energies.
Conclusion: A Triumph for Einstein’s Theory
Senior Editor: what are the key takeaways from this study?
Dr. Maria Gonzalez: This study reaffirms the robustness of Einstein’s special relativity,even under the extreme conditions of the LHC. It also demonstrates the incredible precision of modern particle physics experiments and sets the stage for future discoveries. While we continue to push the boundaries of physics, Einstein’s theories remain as relevant and groundbreaking as ever.
