SUMMARY:ECAP Seminar: Forcing neutrinos to obey the holographic principle (
 Dr. Oliver Friedrich (LMU))
DESCRIPTION:Gravity does not like the vast amounts of states present in QFT
 \, and\nquantum gravitational effects are expected to drastically reduce t
 he\ndimension of the QFT Hilbert space. This is e.g. achieved by "operator
 \ndressing"\, which changes the commutation relations of quantum fields.\n
 In https://arxiv.org/abs/2402.11016  we build a model for neutrinos\,\ntha
 t incorporates this dressing and fixes it such that neutrinos obey\na cosm
 ic entropy bound. A key consequence of this construction is that\nparticle
 s scatter in the vacuum. This e.g. implies a finite mean free\npath of cos
 mic neutrinos. We confront this result with observed\nneutrino emissions a
 nd find that the holographic principle is\npotentially in tension with cur
 rent neutrino data.
