The 4th Workshop on "High Precision for Hard Processes at the LHC" (HP2) will be held from September 4 to September 7, 2012 at the Max Planck Institute for Physics in Munich. The workshop will start Tuesday morning and end Friday 14:00. The conference dinner will take place on Thursday, Sep 6. The conference fee of 50 Euros (includes the conference dinner) should be paid in cash upon arrival. The talks are of 30mins length, including about 5 mins discussion time. Please arrange yourself for accommodation. The website contains links to some hotels nearby. Please note that some of the hotels can keep their special rate only until a certain deadline, and that the conference is close to the Octoberfest, so we recommend early booking. A very limited number of rooms is also available in the MPI guesthouse.
