Speakers: Dr. Victor Goncalves (Universidade Federal de Pelotas, Brasil)
Place: Přednáškový sál v budově FZÚ, Na Slovance 2, Praha 8
Presented in anglicky
Organisers: Division of Elementary Particle Physics

In this talk I will discuss the contribution of the heavy quark production in ultra high energy cosmic ray interactions in the atmosphere considering that the primary cosmic ray can be either a photon, neutrino or a proton. A detailed mapping of the dominant kinematical domains contributing to the prompt atmospheric neutrino flux at high neutrino energies is presented by studying their sensitivity to the cuts on several kinematical variables crucial for charm production in cosmic ray scattering in the atmosphere. Finally, recent results for the prompt tau neutrino flux will be discussed.
