“…However, if we live in a universe with more than three spatial dimensions, microscopic black holes with masses of the order of M G ≃ 1 TeV may be produced by colliding particles in present accelerators or by ultra-high cosmic rays or neutrinos (see, e.g., Refs. [105,106,107,108,109,110,111]). …”

We review the main consequences of the possible existence of a minimum measurable length, of the order of the Planck scale, on quantum effects occurring in black hole physics. In particular, we focus on the ensuing minimum mass for black holes and how modified dispersion relations affect the Hawking decay, both in four space-time dimensions and in models with extra spatial dimensions. In the latter case, we briefly discuss possible phenomenological signatures. Gravity and minimum lengthPhysics is characterized by a variety of research fields and diversified tools of investigation that strongly depend on the length scales under consideration. As a result, one finds an array of sub-disciplines, spanning from cosmology, to astrophysics, geophysics, molecular and atomic physics, nuclear and particle physics. In a nutshell, we can say that Physics concerns events occurring at scales between the radius of the Universe and the typical size of observed elementary particles. It is not hard to understand that such a rich array of physical phenomena requires specific formalisms. For instance, at macroscopic scales, models of the Universe are obtained in terms of general relativity, while at microscopic scales quantum physics has been proven to be the adequate theory for the miniaturised world.

“…Using this method with the surface detectors from the PAO, the duty cycle will be about 100%, and will considerably increase the statistics of the events with E > 10 19 eV . This method will also be useful when searching for the quantum black holes signature proposed in [9].…”

Abstract. We study the possibility of primary mass estimation for Ultra High Energy Cosmic Rays (UHECR's) using the X μ max (the height where the number of muons produced on the core of Extensive Air Showers (EAS) is maximum) and the number N μ of muons detected on ground. We use the 2D distribution -X μ max against N μ in order to find its sensitivity to the mass of the primary particle. For that, we construct a 2D Probability Function Prob(p, Fe | X μ max , N μ ) which estimates the probability that a certain point from the plane (X μ max , N μ ) corresponds to a shower induced by a proton, respectively an iron nucleus. To test the procedure, we analyze a set of simulated EAS induced by protons and iron nuclei at energies of 10 19 eV and 20 • zenith angle with CORSIKA. Using the Bayesian approach and taking into account the geometry of the infill detectors from the Pierre Auger Observatory, we observe an improvement in the accuracy of the primary mass reconstruction in comparison with the results obtained using only the X μ max distributions.

“…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.
