Sensitivity study of µ and τ neutrino on ν r-process — •Heamin Ko1, Zewei Xiong2, and Gabriel Martínez-Pinedo1,2 — 1Institut für Kernphysik, Fachbereich Physik, TU Darmstadt, Darmstadt, Germany — 2GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany
In neutron-rich environments, large neutron fluxes can be absorbed by nuclei, which means that neutron-nucleus reactions can push matter beyond the stability line through charge-current reactions and produce p-nuclei. This new process is called the ν r-process. In this work, we study the sensitivity of the heavier neutrinos (µ and τ neutrinos). In this talk, we will show the contribution of the heavier neutrinos to the neutral current reaction by varying the parameters of the heavier neutrinos, such as flux and temperature.
This work is supported by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) through Project - ID 279384907 - SFB 1245.
