High energetic neutrinos coming from space can interact either in the atmosphere
or in the Earth. In the first scenario neutrino may initiate extensive air showers
(EAS) in the atmosphere, but due to their very small interaction cross section in air
only very inclined EAS might be detectable by large detectors. In the second scenario
neutrino may interact inside the Earth and prod

The properties of extremely energetic neutrino- and cosmic ray-induced
showers depend on the shower energy, on the type of particle initiating the shower,
and on the medium. Studying these dependences is important both for understanding
cascade phenomenology, and for estimating the efficiency of experiments using the radio
technique. In this contribution we study the feasibility of applying

We present a re-analysis of all existing electron and neutrino elastic and quasielastic
scattering data on nucleons. By using theoretical constraints from Quark-Hadron
duality, we obtain new precise parametrizations of vector and axial nucleon form
factors. These new parametrizations are used to improve the predictions for quasielastic
neutrino-nucleon cross sections of GeV neutrinos in the a

A possible signature of a neutrino-induced air shower is a near-horizontal event
developing very deeply in the atmosphere at depths exceeding a few thousand g/cm^2.
Making use of high-statistics shower libraries we study the background to such events from:
(1) high-energy muons produced in primary proton events, which may propagate deeply
into the atmosphere before initiating a subcascade;

The atmospheric neutrino is still an important tool in the study
of neutrino physics. The uncertainty of the predicted atmospheric
neutrino flux is caused by the uncertainties in the physical
assumptions and in the calculation scheme.
We discuss them quantitatively, and present the works to reduce them.
The uncertainty related to the hadronic interaction model was
discussed before, the

The Lunar Cherenkov technique, which aims to detect the coherent Cherenkov
radiation
produced when UHE particles interact in the lunar regolith, was first attempted
with
the Parkes radio-telescope in 1995, though the theory was not sufficiently
developed
at this time to calculate a limit on the UHE neutrino flux from the non-
observation.
Since then, the technique has evolved to includ

Starting from a survey of experimental measurements, we assign uncertainties to the
two most critical inputs to the calculation of fluxes of unoscillated atmospheric
neutrinos, the hadron production and the primary cosmic ray fluxes. We then
propagate these uncertainties through the entire flux calculation to arrive at
estimates of the uncertainties in the fluxes of neutrinos and of various r
