Nuclear Theory/RIKEN Seminar

"Prompt atmospheric neutrino flux and forward charm production in proton-nucleus collisions"

Presented by Anna Stasto, Penn State

Friday, January 6, 2017, 2:00 pm — Small Seminar Room, Bldg. 510

The discoveries of the extraterrestrial neutrino flux by IceCube renewed interest in the precise evaluation of the background neutrinos

which are produced in the atmosphere due the cosmic ray interactions. One of the most relevant processes at high energies is the charm and beauty production

in proton-nucleus collisions which needs to be evaluated at very high energies where small x effects may become important.

I will discuss a recent calculation of the forward charm production in pp and pA, and compare results from different models

which include small x effects due to resummation and saturation. Comparison with the LHC data will be presented and nuclear effects on light nuclei will also be discussed.

Finally, I will show the resulting prompt neutrino flux and its uncertainties and discuss the potential improvements.
