09:41:17 From Peter Denton (he/him) to Everyone: Please mute your mics if you are not speaking 09:56:40 From Mary Bishai to Everyone: There is also an irreducible nue CC background from the beam - at these energies ke3 decays contribute. 10:01:03 From Pedro Machado, Fermilab to Everyone: Yes, we did include the beam contamination in our backgrounds 10:04:30 From Peter Denton (he/him) to Everyone: Pedro (and Adam and others), it would be interesting to know what is a "best conceivable reconstruction" and on the other end how much uncertainty we get by swapping event generators 10:08:12 From John Krizmanic to Everyone: At 3 GeV, it looks like the coherent pi0 cross section is ~5% of that for NC deep inelastic and ~13% of NC single pion cross section, this seems to indicate that coh pi0 is a smaller part of the background, ignoring event acceptance differences. 10:25:28 From Mary Bishai to Everyone: My comment is that for the numu->nutau (question really for Pedro) 30% is actually QE. So for tau->e selection I am surprised the S/sqrt(B) is that good. 10:26:18 From Pedro Machado, Fermilab to Everyone: you mean 30% for the CP-opt or for tau-opt beam? 10:26:43 From Mary Bishai to Everyone: For tau-opt -this was a simple calculation using GENIE cross-sections 10:27:03 From Mary Bishai to Everyone: Maybe in discussion session we can dig in. 11:00:22 From Sebastian Trojanowski to Everyone: + 12:28:59 From D. Jason Koskinen to Everyone: While the signal for astrophysical neutrinos in IceCube might not so much helped in the forward region, the background for astrophysical high-energy astrophysical neutrinos can be improved by better resolution in the forward region, e.g. very low x 12:31:52 From Peter Denton (he/him) to Everyone: We looked at nutau UHE neutrino cross sections at 1 EeV and we are close to the region where pdf's become relevant and some NNPDF people reached out to us
