Minimum bias and early QCD physics at LHC

An overview of early measurements expected from the ATLAS and the CMS experiment on the properties of proton-proton interactions at the Large Hadron Collider (LHC) is presented. As the LHC will open a new kinematic regime, it is important to validate especially the phenomenological modelling of non-perturbative effects with data by performing with initial data detailed measurements of the basic properties of proton-proton collisions in the multi-TeV regime. Examples of possible measurements in the areas of minimum bias physics, underlying event physics and jet physics are given.
