“…An accuracy of better than 1 • is achieved for energies above 10 TeV and track lengths greater than 300 m. This precision will allow for significant contributions to multi-messenger searches for neutrino sources via the transmission of neutrino alerts. GVD already participates in follow-up analyses [625].

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, high-energy and ultrahigh-energy neutrinos probe fundamental physics from the TeV scale to the EeV scale and beyond. They are sensitive to physics both within and beyond the Standard Model through their production mechanisms and in their propagation over cosmological distances. They carry unique information about their extreme non-thermal sources by giving insight into regions that are opaque to electromagnetic radiation. This white paper describes the opportunities astrophysical neutrino observations offer for astrophysics and high-energy physics, today and in coming years.Fully opening the HE and UHE neutrino windows requires a multi-pronged approach that explores a broad range of proposed experimental techniques. With upcoming neutrino telescopes, the goal is to improve the sensitivity ten-fold in the HE range and hundred-fold in the UHE range. In the HE range, we are moving into the high-statistics era, where subtle features may be resolved and multiple sources may be discovered. In the UHE range, neutrino flux predictions and physics tests are well-motivated, but we will likely need new techniques to enable discoveries. The ongoing efforts to develop new instruments will improve sensitivity, increase statistics, and expand the energy range. A broad range of experimental approaches, with complementary capabilities, must be developed and tested in the coming decades. Because it is not clear which techniques will prevail, we advocate for a broad portfolio of experiments in the HE and UHE neutrino sector. Owing to their potential, HE and UHE neutrinos should be at the forefront of the high-energy physics program, as they push the boundaries for the neutrino, cosmic, energy, theory, and instrumentation frontiers. 4 Experimental landscape 32 4.1 Overview 32 4.2 High-energy range 35 4.3 Ultra-High Energy Range (> 100-PeV) 45

“…Thus we can infer from the analysis that the highenergy atmospheric neutrino spectra calculated with the consistent scheme [19,[24][25][26][27][28][29] are sufficiently reliable and might be suitable for numerical simulation of the atmospheric neutrino events in the operating neutrino telescopes, as well as in the future experiments, Baikal-GVD [55][56][57], IceCube-Gen2 [58,59], and KM3NeT/ORCA [60]. We expect that increased statistics on the muon, electron and tau neutrino events due to functional capabilities of the next generation of neutrino telescopes will enable one to solve the prompt neutrino problem.…”

Statistical analysis is performed of the atmospheric neutrino flux models as compared with the data of Frejus, AMANDA-II, IceCube, ANTARES, and Super-Kamiokande experiments. The main objective is to characterize models of hadron-nucleus interactions from the point of view of the statistical significance of the atmospheric neutrino flux predictions compared to the measurements. The flux calculations were performed in the framework of the single computational scheme involving a set of hadronic models combined with parameterizations of the primary cosmic rays spectrum by Hillas & Gaisser and Zatsepin & Sokolskaya. The analysis showed satisfactory agreement of the conventional νµ flux calculations with the measurements. The prompt neutrinos conrtibution obtained with a set of charm production models (QGSM, SIBYLL 2.3c, PROSA, GRRST, BEJKRSS, and GM-VFNS) is statistically negligible in the energy range covered by the neutrino telescopes.

“…are restricted, this allows to consider only well-reconstructed cascadelike events [16], [9]. Since the majority of Baikal-GVD real data are events from atmospheric background, with a goal to estimate a probability not to be an astrophysical event, we used mixed real data samples of 2018-2019 years as the background [12]. The prompt search of Baikal-GVD towards directions of all received IceCube alerts within a time window ±500 seconds did not reveal any associations with them.…”

“…In the absence of significant correlations with IceCube alerts in the season 2020, the upper limits at 90% c.l. on the neutrino fluence in each alert arrival direction for the E −2 spectrum in the source have been obtained [12]. At the beginning of 2021, the Baikal-GVD own alert system was launched, that allows monitoring of the celestial sphere in real time.…”

The Baikal Gigaton Volume Detector is a neutrino telescope of a km 3 scale currently under construction in lake Baikal. Baikal-GVD participates in the international multi-messenger program at earlier stages of its construction. Since autumn 2020 Baikal-GVD follows up of the IceCube neutrino astrotracks. Recent results of fast follow-up searches for time-and-direction correlation of Baikal-GVD high-energy cascades with IceCube GCN messages are presented.
