SUMMARY:Measuring the neutrino-nucleon cross section at ultra-high ene
 rgies: detailed forecasts for IceCube-Gen2\, NPAC (Nuclear/Particle/As

DESCRIPTION:Ultra-high-energy (UHE) neutrinos\, energetic (> 100 PeV) 
 but rare\, have evaded detection for decades\, but might soon be withi
 n the reach of upcoming neutrino telescopes. With them\, we could meas
 ure for the first time UHE neutrino-matter interactions\, allowing us 
 to probe protons and neutrons deeper than before and to look for new h
 igh-energy physics. We present detailed measurement forecasts of the U
 HE neutrino-nucleon cross section\, geared at radio-detection in IceCu
 be-Gen2\, with the aim of informing its science capabilities. We use s
 tate-of-the-art ingredients throughout: in the neutrino flux\, in-Eart
 h attenuation\, Askaryan radio emission and propagation\, detector mod
 eling\, and non-neutrino backgrounds. After 10 years\, if at least a f
 ew tens of events are detected\, we could measure the cross section at
  center-of-mass energies of 10-100 TeV for the first time\, with a pre
 cision comparable to that of its theory prediction.
