LHC’s failure to find new particles casts doubt on supersymmetry

Science News : Despite exposing the Higgs boson in 2012, the Large Hadron Collider, the world’s largest and most powerful particle accelerator, has so far failed to turn up evidence of any of the new particles predicted by the theory of supersymmetry. According to the theory, all the known fundamental particles have more massive counterparts. The failure to turn up evidence of those larger particles does not necessarily disprove supersymmetry, some scientists say. It’s possible that the particle predictions may simply need to be modified; the new particles may be much heavier than expected. For other physicists, the lack of data indicates that new theories, such as the relaxation hypothesis or neutral naturalness , should be considered.
