Constraints on Torsion from Lorentz Violation
Alan Kostelecky🇺🇸 · Neil Russell🇺🇸 · Jay Tasson🇺🇸
Abstract
Exceptional sensitivity to spacetime torsion can be achieved by searching for its couplings to fermions. Recent experimental searches for Lorentz violation are exploited to extract new constraints involving 19 of the 24 independent torsion components down to levels of order 10^{-31} GeV.
