The age parameter in giant EAS

Abstract : The age parameter from the longitudinal development can be used to describe the lateral distribution in giant EAS up to 5km from the axis, even if the scaling properties of Approximation B in cascade theory fail after $3.5$ Moliere radii. A set of analytic descriptions is proposed under the gaussian hypergeometric formalism replacing the Eulerian formalism of the classical NKG distribution, valid for electrons, muons and vertical equivalent muons (v.e.m.).
