“…Also direct a production at colliders is strongly suppressed. Nevertheless, (quasi-) stable τ 1 's could appear in collider detectors (and neutrino telescopes [344]) as a possible signature of the a LSP. However, since the M P measurement at colliders [351], which would have been a decisive test of the G LSP, seems cosmologically disfavored in most of the parameter space of R-parity conserving SUSY models, it may very well be a challenge to distinguish between the a LSP and the G LSP.…”

“…Various aspects of this scenario were further considered in Refs. [5,6,7]. In principle one could think that cosmic rays could be an even better source of supersymmetric events, and ultimately of NLSPs.…”

In supersymmetric theories where the lightest supersymmetric particle is the gravitino the next to lightest supersymmetric particle is typically a long lived charged slepton. In this paper, following our earlier proposal [1], we perform a detailed study of the production of pairs of these particles induced by the interactions of high energy cosmic neutrinos with nucleons in the earth, their propagation through the earth and finally their detection in neutrino telescopes. We investigate the charged slepton energy loss in detail and establish that the relatively small cross-section for the production of supersymmetric particles is partially compensated for by the very long range of these heavy particles. The signal, consisting of two parallel charged tracks emerging from the earth, is characterized by a track separation of a few hundred meters. We perform a careful analysis of the main background, coming from direct di-muon production, and show that it can be separated from the signal due to its characteristically smaller track separation. We conclude that neutrino telescopes will complement collider searches in the determination of the supersymmetry breaking scale, and may even provide the first evidence for supersymmetry at the weak scale.

“…It also implies that ℓ (1) can be produced by the interactions of high energy neutrinos with the earth and propagate through it until reaching a detector, in very close analogy to the case of NLSP sleptons studied in Refs. [9,10,11,12,13]. We will show that interactions of high energy neutrinos (E ν > 10 5 GeV) with nucleons in the Earth will produce pairs of NLKPs.…”

In theories with universal extra dimensions (UEDs), all standard model fields propagate in the bulk and the lightest state of the first Kaluza-Klein (KK) level can be made stable by imposing a Z2 parity. We consider a framework where the lightest KK particle (LKP) is a neutral, extremely weakly interacting particle such as the first KK excitation of the graviton, while the next-to-lightest KK particle (NLKP) is the first KK mode of a charged right-handed lepton. In such a scenario, due to its very small couplings to the LKP, the NLKP is long-lived. We investigate the production of these particles from the interaction of high energy neutrinos with nucleons in the Earth, and determine the rate of NLKP events in neutrino telescopes. Using the Waxman-Bahcall limit for the neutrino flux, we find that the rate can be as large as a few hundreds events a year for realistic values of the NLKP mass.
