Physics Colloquium

"High energy atmospheric neutrinos: connections between laboratory experiments and cosmic rays"

Presented by Mary Hall Reno, University of Iowa

Tuesday, June 11, 2019, 3:30 pm — Large Seminar Room, Bldg. 510

The IceCube Neutrino Observatory's measurement of a diffuse flux of neutrinos from astrophysical sources has opened a new era in high energy astroparticle physics. Neutrinos produced by cosmic ray interactions in the atmosphere are the main background to the astrophysical neutrino flux. At these high energies, data from the Large Hadron Collider experiments on heavy flavor production can be used to narrow the uncertainties in the background predictions at the highest energies. Our evaluation of the atmospheric neutrino flux from charm will be used to illustrate how collider physics results are connected to cosmic ray physics in this context.
