Re: Proposal for new Physics Vector classes in ROOT

Hi Valery,

  as it is written in in the linked Web page, the latest version can be downloaded from

  http://seal.web.cern.ch/seal/MathLibs/GenVector/GenVector.tgz

But bare in mind, that the code is just for looking at the API, the implementations are not yet finalized and fully tested. We expect to release the first version with ROOT version 5 at the end of the months.

  Best Regards,

  Lorenzo
