An inclusive search for dimuons at IceCube

As a landmark project in the field of particle physics, the IceCube Neutrino Observatory has measured various neutrino interactions in the 15 years of its operation. The data collected by the array has yielded a great amount of insight into the behavior of neutrinos, the standard model, and potentially beyond. Many collaborators on the project utilize the data to make a number of different observations. IceTray, a digital framework for simulating IceCube data, has proved particularly useful in cataloging neutrino phenomena.

As part of the greater IceCube collaboration with Harvard LPPC, work was done on the simulated reconstruction of charm-production dimuon events using IceTray. Charm-induced dimuon interactions from neutrino deep-inelastic scattering offer a sensitive probe of the proton’s parton structure. Recent advances in reconstruction at the IceCube Neutrino Observatory now permit searches for these events at energies unreachable by other neutrino-based experiments. This work will present the latest progress in an inclusive dimuon search at IceCube, showcasing event rates and kinematics. Identifying a dimuon signal will enable the first measurement of the proton’s strange sea with neutrinos at multi-TeV energies.
