“…Neutrino physics has been achieving significant results and development in the last twenty years [1], such as the first detection of tau neutrinos [2], the confirmation of neutrino oscillations [3], etc. Big part of these achievements were attainable just after the construction and improvement of several neutrino detectors as the Super-Kamiokande [4], IceCube [5], MinibooNE [6], among others that allowed more detailed studies of neutrino interactions at different energy scales.…”

Despite not have been yet identified by the IceCube detector, events generated from ν τ deep inelastic neutrino scattering in ice with varied topologies, such as double cascades (often called double bangs), lollipops and sugardaddies, constitute a potential laboratory for low-x parton studies. Here we investigate these events, analyzing the effect of next-to-next-to-leading order (NNLO) Parton Distribution Function (PDFs) in the total neutrino-nucleon cross section, as compared with the color dipole formalism, where saturation effects play a major role. Energy deposit profiles in the 'bangs' are also analysed in terms of virtual W -boson and tauon energy distributions and are found to be crucial in establishing a clear signal for gluon distribution determination at very small x. By taking the average (all flavor) neutrino flux (Φ ν ∼ E −2.3 ν ) into differential cross sections as a function of τ and W energies, we find significant deviations from pure DGLAP parton interactions for neutrino energies already at a few PeV. With these findings one aims at providing not only possible observables to be measured in large volume neutrino detectors in the near future, but also theoretical ways of unravelling QCD dynamics using unintegrated neutrino-nucleon cross sections in the ultrahigh-energy frontier. *

“…Furthermore, the Ice-Cube events up to PeV energies have been used to constrain the neutrino cross section for the first time at a center-of-mass (COM) energy as high as ∼ 1 TeV for the neutrino-proton collision [31][32][33]. Besides verifying the SM predictions, UHE neutrino telescopes are also good facilities to probe certain new physics scenarios beyond the SM [34,35]: test of equivalence principle and Lorentz invariance [36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54], unitarity [55][56][57], fifth forces [58], microscopic black holes [59][60][61][62][63][64][65][66][67][68][69][70], monopoles [71][72][73][74][75], neutrino transition magnetic moment [76,…”

We systematically investigate new physics scenarios that can modify the interactions between neutrinos and matter at upcoming tau neutrino telescopes, which will test neutrinoproton collisions with energies 45 TeV, and can provide unique insights to the elusive tau neutrino. At such high energy scales, the impact of parton distribution functions of second and third generations of quarks (usually suppressed) can be comparable to the contribution of first generation with small momentum fraction, hence making tau neutrino telescopes an excellent facility to probe new physics associated with second and third families. Among an inclusive set of particle physics models, we identify new physics scenarios at tree level that can give competitive contributions to the neutrino cross sections while staying within laboratory constraints: charged/neutral Higgs and leptoquarks. Our analysis is close to the actual experimental configurations of the telescopes, and we perform a χ 2 -analysis on the energy and angular distributions of the tau events. By numerically solving the propagation equations of neutrino and tau fluxes in matter, we obtain the sensitivities of representative upcoming tau neutrino telescopes, GRAND, POEMMA and Trinity, to the charged Higgs and leptoquark models. While each of the experiments can achieve a sensitivity better than the current collider reaches for certain models, their combination is remarkably complementary in probing the new physics. In particular, the new physics will affect the energy and angular distributions in different ways at those telescopes.

“…They are probes that allow us to study weak interactions and the internal structure of nucleons and nuclei [1]. At TeV energies, neutrinos allow us to test fundamental physics at energies that are not reachable at laboratories [2] and those in the ultra high energy regime (UHE), starting at ∼100 TeV [3], point back to the most energetic particle accelerators in the Universe. In the GeV-TeV energy range neutrinos are predominantly of atmospheric origin.…”

Characterization of the background for a neutrino search with the HAWC observatory

The close location of the HAWC observatory to the largest volcano in Mexico allows to perform a search for neutrino-induced horizontal muons. The section of the volcano located at the horizon reaches values of slant depth larger than 8 km of rock, making it an excellent shield for the cosmic ray horizontal background. We report the search method and background suppression technique developed for HAWC, as well as a model that describes the remaining background produced by scattered muons. We show that by increasing the detection energy threshold we could use HAWC to search for Earth-skimming neutrinos.
