We shall present the results for a study of some perturbative and nonperturbative effects on the evaluation of the nutau(nutaubar)-nucleon scattering cross sections. The free nucleon structure functions have been obtained by using the evolution of parton distribution functions at the next-to leading order and taking the effects of kinematical and dynamical higher twists. These free nucleon...
The Giant Radio Array for Neutrino Detection (GRAND) project aims to find the sources of Ultra-High Energy Cosmic Rays (UHECRs) in the Universe. This would be achieved by deploying 200,000 radio antennas over 200,000 km2, gathering enough UHE neutrino, cosmic ray and gamma-ray events to pinpoint UHECRs origin. The use of a sparse array of antennas would allow achieving statistics far beyond...
The detection of the radio emission following a neutrino interaction in ice is a promising technique to obtain significant sensitivities to neutrinos with energies above 10 PeV. The detectable radio emission stems from particle showers in the ice. With the RNO-G detector being under construction in Greenland, and the plans for an order-of-magnitude more sensitive radio detector as part of...
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to observe cosmic neutrinos and to identify the sources of ultra-high energy cosmic rays (UHECRs). POEMMA consists of two spacecraft flying in a loose formation at 525 km altitudes with each spacecraft hosting a large Schmidt telescope with a focal plane optimized to observe both the optical Cherenkov signals and the...
We study the sensitivity to axial nucleon structure of single-spin asymmetries in (anti)neutrino charged current quasielastic scattering on free nucleons. The weak interaction gives rise to relatively large single-spin asymmetries at leading order. Besides the axial form factor, the pseudoscalar form factor can be accessed with tau (anti)neutrinos measuring recoil and target transverse...
Heavier neutral leptons are predicted in many extensions of the SM as a solution of several fundamental questions like the origin of the neutrino masses. In this talk, we will consider the detection of HNLs using ''double-bang'' signals. Several models can explain this type of event, here we will consider two: the production of HNLs via mixing with the light neutrinos and through a transition...
Understanding the propagation of neutrinos through matter is fundamental to quantify the sensitivity to detect high-energy tau neutrinos. NuPropEarth is a simulation framework with the structure of a general-purpose Monte Carlo event generator and therefore allows following the path and interactions of individual neutrinos as they travel through Earth on an event-by-event basis. In this talk,...
Do neutrinos have sizable self-interactions? They might. Laboratory constraints are weak, so strong effects are possible in astrophysical environments and the early universe. Observations with neutrino telescopes can provide an independent probe of neutrino self (“secret”) interactions, as the sources are distant and the cosmic neutrino background intervenes. We define a roadmap for making...
