The obtained experimental results show that the tetragonal crystalsymmetry of this system is preserved in Hidden Order within the highest-ever spatial resolution for the detection of orthorhombicity (b' - a')/(b' - a') of ~ 1.0 x 10-5. We also present the tests for the reproducibility of magnetic torque measurements using the same single-crystalline sample to discuss the possible broken symmetry of URu2Si2., The International Conference on Strongly Correlated Electron Systems}, title = {Experimental Tests of Broken Tetragonal Symmetry in Hidden Order of URu2Si2}, year = {2017} }
