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…
Primordial bubbles of colour superconducting quark matter
Luis Masperi, Milva Orsaria
We analyze the possibility that bubbles of quark matter surviving the confinement phase transition might have become colour superconducting due to the enormous compression suffered…
Strangelets and their possible astrophysical origin
Luis Masperi
We discuss the first-order phase transition of QCD at high temperature in the universe and the possible formation of quark-matter lumps through cooling in regions of increased pres…
Comparison of UHECR spectra from necklaces and vortons
Luis Masperi, Milva Orsaria
Cosmic rays of energy higher than 10^19 eV may be explained by topological defects produced in the early stages of universe. Two suitable alternatives are: necklaces formed by magn…
Hard component of ultra-high energy cosmic rays and vortons
Luis Masperi, Milva Orsaria
Observed events of ultra-high energy cosmic rays may indicate a hard component for the energy spectrum of their flux, which might have origin in the decay of long-lived vortons pre…
Baryogenesis through gradual collapse of vortons
Luis Masperi, Milva Orsaria
We evaluate the matter-antimatter asymmetry produced by emission of fermionic carriers from vortons which are assumed to be destabilized at the electroweak phase transition.The vel…
Cosmic Rays from Decaying Vortons
Luis Masperi, Guillermo Silva
The flux of high energy cosmic rays coming from the decay of vortons is estimated. If the abundance of loops corresponding to a superconductivity scale coincident with that of the…
Influence of Strings with Axionic Content on the Polarization of Extragalactic Sources
Luis Masperi, Sandra Savaglio
It is shown that the axion concentrated in electroweak strings which are consequently stabilized may produce a rotation of the polarization angle of radiation from extragalactic so…
