Large Hadron Collider data analysis finds no evidence of quantum black holes
ScienceDaily reports that UC Santa Barbara physicists used collider data to constrain extra-dimension models up to 12 TeV.
The short version
- University of California Santa Barbara researchers analyzed Large Hadron Collider data collected from 2016 to 2018 and identified no signs of microscopic quantum black holes.[ScienceDaily]
- Under the specific theoretical models tested, the findings exclude quantum black hole production up to approximately 12 TeV and indicate no more than two extra spatial dimensions can exist.[ScienceDaily]
- The analysis marked the first particle physics application of a phase-space distance method, which outperformed traditional sphericity metrics in filtering collision data.[ScienceDaily]
Key facts
- Physicists at the University of California Santa Barbara analyzed CMS detector data from 2016 through 2018 and found no evidence of microscopic quantum black holes.[ScienceDaily]
- Under the theoretical models evaluated, quantum black hole creation is ruled out up to roughly 12 TeV.[ScienceDaily]
- Assuming the examined model parameters hold, the observations indicate there cannot be more than two extra spatial dimensions.[ScienceDaily]
- The study utilized a machine-learning-assisted phase-space distance technique for the first time in particle physics, outperforming the conventional sphericity metric.[ScienceDaily]
What remains uncertain
- The conclusions establish exclusion limits conditioned strictly on the specific parameters and theoretical models examined rather than an absolute disproof of all quantum gravity frameworks.[ScienceDaily]
