  The successful operation of the {\em Large Hadron Collider} (LHC) during the
past two years allowed to explore particle interaction in a new energy regime.
Measurements of important Standard Model processes like the production of
high-\pt\ jets, $W$ and $Z$ bosons and top and $b$-quarks were performed by the
LHC experiments. In addition, the high collision energy allowed to search for
new particles in so far unexplored mass regions. Important constraints on the
existence of new particles predicted in many models of physics beyond the
Standard Model could be established. With integrated luminosities reaching
values around 5 \ifb\ in 2011, the experiments reached as well sensitivity to
probe the existence of the Standard Model Higgs boson over a large mass range.
In the present report the major physics results obtained by the two
general-purpose experiments ATLAS and CMS are summarized.
