Recently at LHC one has obtained measurements of the total, elastic anddiffractive cross sections in pp collisions at very high energy. The totalcross section is in good agreement with predictions based on a leading behavior\sigma_{tot} (s) \propto (\ln s/s_0)^2, on the other hand the elastic crosssection is lower than most expectations and the diffractive cross section ishigher. It is remarkable that the ratio  (\sigma_{el} + \sigma_{diff})/\sigma_{tot} calculated combining the resultsof the TOTEM and ALICE detectors is 0.495^{+0.05}_{-0.06}, very close to themaximum theoretically allowed value of 1/2 known as the Miettinen Pumplinbound. In this work we discuss these results using the frameworks of single andmulti--channel eikonal models, and outline the main difficulties for aconsistent interpretation of the data.

Interpretation of the measurements of total, elastic and diffractive cross sections at LHC
