Earth and Planetary Science with muons and neutrinos
Oral
Primary cosmic-protons and nuclei interact in the atmosphere and produce cascades of secondary hadrons, some of which decay to produce muons and neutrinos. Production of pions, kaons and other hadrons occurs at the level of nucleon-nucleon interactions. For example, the excess of positive muons is a consequence of the excess of protons over neutrons in the primary spectrum of cosmic-ray...

Earth and Planetary Science with muons and neutrinos
Oral
At sea level the flux of charged particles is dominated by muons, which originated by the decay of mesons produced by the interactions of primary cosmic rays at the top of the atmosphere. Due to their relative stability and small cross sections, these particle are able to arrive deep under-ground, -water or -ice. As a consequence, their penetration properties opens the possibility of...

Earth and Planetary Science with muons and neutrinos
Oral
Electron anti-neutrinos produced by natural radioactivity inside the Earth - geoneutrinos - can be used as a unique direct probe in order to determine the amount of long-lived radioactive elements inside our planet and to constrain the radiogenic contribution to the terrestrial heat. The composition of the Earth's interior, the heat sources driving the mantle convection, the generation of the...

Earth and Planetary Science with muons and neutrinos
Oral
In spring of 2011, the world's largest neutrino observatory, IceCube, was completed within deep glacial ice at the South Pole.
IceCube is designed to detect Cherenkov light emitted by secondary charged particles generated from high-energy neutrinos.
The primary mission of IceCube is to discover the origin of cosmic neutrinos, while detailed studies of the atmospheric neutrino background have...

Earth and Planetary Science with muons and neutrinos
Oral
The main source of background for the radiography of volcanoes with atmospheric muons comes from the accidental coincidences produced in the telescopes by the atmospheric showers.
In order to quantify this background, the showers were investigated using two MonteCarlo packages, Corsika[1] and Geant4[2]. The talk will describe the simulation chain and give very preliminary results on the...
