Inelastic Black Hole Production and Large Extra Dimensions
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
Black hole production in elementary particle collisions is among the most promising probes of large extra spacetime dimensions. Studies of black holes at particle colliders have as…
Galactic Point Sources of TeV Antineutrinos
Luis A. Anchordoqui, Haim Goldberg, Francis Halzen +1
High energy cosmic ray experiments have identified an excess from the region of the Galactic Plane in a limited energy range around eV (EeV). This is very suggestive of n…
Quest for Black Holes and Superstring Excitations in Cosmic Ray Data
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
In this talk we discuss aspects of TeV-scale gravitational collapse to black holes and string balls and their subsequent evaporation. Special emphasis is placed on the interplay of…
Footprints of Super-GZK Cosmic Rays in the Pilliga State Forest
Luis Anchordoqui, Haim Goldberg
High energy cosmic ray data collected by the SUGAR Collaboration in the Pilliga State Forest have been re-analyzed using up-to-date shower simulations. Complete, inclined angle, Mo…
A Study Of Very Inclined Showers In The Pierre Auger Observatory
M. Ave
The Engineering Array of the Auger Observatory has been running successfully since 2001 and inclined showers have been recorded from the start. We have analysed the events with zen…
Calibration of the Pierre Auger fluorescence detector
M. D. Roberts
The absolute calibration of an air fluorescence detector (FD) is an important element in correctly determining the energy of detected cosmic rays. The absolute calibration relates…
On the cross correlation between the arrival direction of ultra-high energy cosmic rays, BL Lacertae, and EGRET detections: A new way to identify EGRET sources?
Diego F. Torres, Stephen Reucroft, Olaf Reimer +1
With the aim of testing recent claims for a particularly strong correlation between ultra-high energy cosmic rays (UHECRs), observed with the AGASA and the Yakutsk experiments, and…
Updated Limits on TeV-Scale Gravity from Absence of Neutrino Cosmic Ray Showers Mediated by Black Holes
Luis A. Anchordoqui, Jonathan L. Feng, Haim Goldberg +1
We revise existing limits on the D-dimensional Planck scale M_D from the nonobservation of microscopic black holes produced by high energy cosmic neutrinos in scenarios with D=4+n…
Prospects for discovery of physics beyond the Standard Model at the Pierre Auger Observatory
Luis A. Anchordoqui
I summarize the discovery potential for physics beyond the electroweak scale at the Pierre Auger Observatory. This observatory is designed to study ultra-high energy cosmic rays wi…
Time Variation of the Fine Structure Constant Driven by Quintessence
Luis Anchordoqui, Haim Goldberg
There are indications from the study of quasar absorption spectra that the fine structure constant may have been measurably smaller for redshifts Analyses of other data…
