IceCube probes for quantum gravity using astrophysical neutrino flavors

The IceCube Collaboration, which includes members from our COST Action CA18108, has presented the results of its search for the effect of quantum gravity on the flavors of astrophysical neutrinos. Although no evidence was found for quantum gravity effects, the result presented is the first to reach the expected signal region of quantum gravity using neutrino flavor interferometry. This study was published today as a letter in the journal Nature Physics.
