Signatures of Precocious Unification in Orbiting Detectors
نویسنده
چکیده
It has been conjectured that the string and unification scales may be substantially lower than previously believed, perhaps a few TeV. In scenarios of this type, orbiting detectors such OWL or AIRWATCH can observe spectacular phenomena at trans-GZK energies. We explore measurable signatures of the hypothesis that trans-GZK air showeres (“anomalous showers”) are originated by strongly interacting neutrinos. The results of a MC simulation of such air showers is described. A distinction between proton induced and “anomalous” showers becomes possible once a substantial sample of trans-GZK showers will be available.

Particle Candidates of Ultrahigh Energy Cosmic Rays
We discuss candidates for trans-GZK cosmic rays observed in a variety of detectors. Three types of primaries are represented among the abstracts submitted to this meeting: neutrinos causing a Z-burst, protons arising from the decay of ultra-heavy metastable particles and neutrinos within the framework of low scale string-like models of unification. We attempt to evaluate the relative merits of ...
متن کاملDynamics of nonlinear rectangular plates subjected to an orbiting mass based on shear deformation plate theory
In this paper, transverse and longitudinal vibration of nonlinear plate under exciting of orbiting mass is considered based on first-order shear deformation theory. The nonlinear governing equation of motion are discretized by the finite element method in combination with Newmark’s time integration scheme under von Karman strain-displacement assumptions. For validation of method and formulation...
متن کاملWhether all patients with Central precocious puberty should be treated?
Extended Abstract Precocious puberty is the appearance of secondary sexual characteristics before 8 years old in girls and 9 years old in boys. Precocious puberty is divided into 3 groups of central, peripheral and normal variants. Central precocious puberty is accompanied by activation of hypothalamic-pituitary-gonadal axis which causes increase in secretion of GnRH, and in turn increase i...
متن کاملHadronic interactions, precocious unification, and cosmic ray showers at Auger energies
At Auger energies only model predictions enable us to extract primary cosmic ray features. The simulation of the shower evolution depends sensitively on the first few interactions, necessarily related to the quality of our understanding of high energy hadronic collisions. Distortions of the standard “soft semi-hard” scenario include novel large compact dimensions and a string or quantum gravity...
متن کاملSignatures of the Cusp and Flux Transfer Events
The usual interpretation of a flux transfer event (FTE) at the magnetopause, in terms of time-dependent and possibly patchy reconnection, demands that it generate an ionospheric signature. Recent ground-based observations have revealed that auroral transients in the cusp/cleft region have all the characteristics required of FTE effects. However, signatures in the major available dataset, namely...
