SUMMARY:ECAP Seminar: Oliver Friedrich\, LMU Sternwarte
DESCRIPTION:Forcing neutrinos to obey the holographic principle\nGravity does not like the vast amounts of states present in QFT\, and\nquantum gravitational effects are expected to drastically reduce the\ndimension of the QFT Hilbert space. This is e.g. achieved by “operator\ndressing”\, which changes the commutation relations of quantum fields.\nIn https://arxiv.org/abs/2402.11016 we build a model for neutrinos\,\nthat incorporates this dressing and fixes it such that neutrinos obey\na cosmic entropy bound. A key consequence of this construction is that\nparticles scatter in the vacuum. This e.g. implies a finite mean free\npath of cosmic neutrinos. We confront this result with observed\nneutrino emissions and find that the holographic principle is\npotentially in tension with current neutrino data.
