Rodrigo,

Many informative sites come up on www.google.com for the phrase "cauchy distribution"
e.g.,
The Cauchy Distribution. ... The Cauchy distribution is symmetric around zero, and bell-shaped, but it has considerably heavier tails than the normal distribution. ...

and
http://www.wikipedia.org/wiki/Cauchy_distribution
"The standard Cauchy distribution is a probability distribution with probability density function
f(x) = 1 / (p (1+x2)).
It is often cited as an example of a distribution which has no mean, variance or higher moments defined, although its mode and median are well defined and both zero. "
