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]
