Parton Shower and Resummation Institute  takes place in DESY Hamburg on May 4-29, 2009. Our aim is to bring together mainly theorists to discuss about various aspect of the parton shower algorithms  and the re-summation schemes. The format of the workshop is rather unconventional. We would like to spend more time on discussion than having formal talks. 

This event is supported by the Strategic Helmholtz Alliance 'Physics at the Terascale'

Please note that the Photon09 International Workshop takes place in DESY on dates May 11-15. You can get more information from http://photon09.desy.de or photon09@mail.desy.de .
