The experiments envisaged at the next generation of hadron colliders will provide the opportunity to search for new physics: for instance, the search for heavy leptons, supersymmetric particles, the Higgs particle(s), and the additional vector bosons predicted in many possible extensions of the Standard Model. The achievement of these various research programs will rely also on the performances of the hadron calorimeters. Their performance are determined by their relative response to the electromagnetic (e) and hadronic ([pi]) shower, measured by the e/[pi] signal ratio. In a hadron sampling calorimeter with silicon readout, a combination of plates of low-Z (Fe) and high-Z (Pb) materials used as absorbers enables the reduction of the calorimeter response to the electromagnetic component of the incoming hadronic shower. This reduction is produced by a filtering effect. As a result, a ratio, varying from e/[pi] > 1 to e/[pi] < 1 is obtained as a function of the low-Z material thickness, demonstrating the possibility to achieve the compensation condition (e/[pi] = 1).
