IceCube and GRB neutrinos propagating in quantum spacetime

   Vrijeme: 11:30 sati
   Mjesto: IRB, seminar ZTFa



Sazetak:

Some recent publications have reported intriguing analyses, tentatively
suggesting that some aspects of IceCube data might be manifestations of
quantum-gravity-modified laws of propagation for neutrinos.
I will show a strategy of data analysis which has the advantage of being
applicable to several alternative possibilities for the laws of propagation
of neutrinos in a quantum spacetime.
In all scenarios here of interest one should find a correlation between the
energy of an observed neutrino and the difference between the time of
observation of that neutrino and the trigger time of a GRB.
I'll show how to select accordingly some GRB-neutrino candidates among
IceCube events, and the data analysis finds a rather strong such
correlation. This sort of studies naturally lends itself to the introduction
of a "false alarm probability", which for this analysis can be estimate
conservatively to be of 1%. Very far from being a discovery, those findings
should however motivate a vigorous program of investigation following the
strategy that I will discuss in detail in this talk.
