In supersymmetric (SUSY) theories1, the photino is the fermion partner of the photon and is expected to be the lightest stable particle. Despite many discussions of the possible production of photinos, and other supersymmetric particles, at existing and proposed accelerators2, so far, experiments have only set limits3,4. We propose here that photinos are produced by sources of ultra-high-energy cosmic rays. We specifically consider Cygnus X-3, which is a powerful source of neutral particles up…

Cosmic Accelerators: A New Era of Cosmic Ray Astrophysics and Particle Physics
A new generation of cosmic ray experiments will be able to measure γN → πX photoproduction for γ-energies exceeding 100 TeV using tagged photon beams emitted by cosmic accelerators. A source such as
Ultra-high energy neutrino-nucleon and neutrino-electron cross-sections in the standard model, in supersymmetric and superstring models
The neutrino-nucleon cross-section is calculated for energies up to 1015 GeV in the framework of the standard model assuming that the nucleon structure functionF2(x, Q2) goes like ln2(a/x) asx→0. The
Muons from high-energy cosmic photino
SummaryThe muon production at photino-nucleon $$(\bar \gamma \mathcal{N})$$ interaction for high-energy photino (E⊂)104GeV) is studied. The production of muons is the result of the creation and the
Sneutrinos from Cygnus X-3?
The possibility that the underground muons arriving from Cygnus X-3 are due to a flux of sneutrinos is analyzed. Crude approximations show that the muons can be due to a resonance production of light

Mass and lifetime limits on supersymmetric particles from a proton beam-dump experiment
Muonless events from the prompt-neutrino experiment at Fermilab have been analyzed to set limits on the masses and decays of supersymmetric particles by means of three measurements; (1) the
Anatomy of a cosmic-ray neutrino source and the Cygnus X-3 system
There is strong evidence that a compact object in the Cygnus X-3 binary system produces an intense beam of ultra-high-energy cosmic rays. Here, we examine the effects of such a beam hitting the
Is Cygnus X-3 a monoenergetic 1017 eV accelerator?
Like many other X-ray sources, Cygnus X-3 seems to be a binary system that includes a compact object, but it is unusual in being enshrouded in gas, in displaying occasional huge outbursts and in
The production of very high energy photons and neutrinos from cosmic proton sources
The emission of neutrinos and photons with energies of the order of 10/sup 12/ eV from the matter surrounding a source of very high energy cosmic ray protos is computed. The optimum conditions for
Possible supersymmetry scenario for pp-bar collider monojet events and unaccompanied ''photon'' events
Anomalous missing-p/sub T/ events observed at the CERN pp-bar collider can be plausibly explained by the photino decay mode q..-->..qgamma-tilde of scalar quarks with mass approx.100 GeV. This gives
First observation of ultra-high-energy γ rays from LMC X-4
Ultra-high-energy γ rays (>1015 eV) have recently been observed from Cygnus X-3 (refs 1, 2) and from Vela X-1 (ref. 3). The discovery that some neutron star binary X-ray sources are emitting
Observation of γ rays >1015 eV from Cygnus X-3
The X-ray binary system Cygnus X-3 is a source of particular interest. As well as emitting X rays which are modulated with a 4.8-h period, it has been observed in 30–100 MeV γ rays by the SAS II
