摘要：

In this paper we present a comparative study between PYTHIA,EPOS,QGSJET,and SIBYLL generators.The global event observables considered are the charged energy flow,charged particle distributions,charged hadron production ratios and V0 ratios.The study is performed in the LHCb and TOTEM fiducial phase spaces on minimum bias simulated data samples for pp collisions at s1/2= 7 TeV,using the reference measurements from these experiments.In the majority of cases,the measurements are within a band defined by the most extreme predictions.The observed differences between the predictions and the measurements seem to be,in most part,caused by extrapolation from the central pseudorapidity region（|η|≤2.5）,in which the generators were mainly tuned.
