This year the US and European HEP communities are engaging in exercises designed to put together plans for the future. In the US it’s Snowmass 2013, leading up to a big meeting in Minneapolis this summer. This past week has seen preliminary meetings at Irvine to discuss future prospects for experimental study of SUSY and other BSM ideas, and at Princeton for discussion of future prospects for study of the Higgs.
Over in Europe, there is a plan to update the 2006 European strategy for particle physics, This will officially take place in May/June, based on a document to be finalized by the CERN Council in March. Next week in Erice there will be a meeting to draft this document. To prepare for this, there was an open symposium last September, leading to the preparation of a briefing book, now available here.
The briefing book is a very interesting 220 page document covering in up-to-date detail the current experimental situation and future prospects, for all areas of HEP. One big issue is the Higgs: now that its mass is known, what can be learned about it using some new machine (a “Higgs factory”) beyond what can be learned from the LHC? As far as prospects for a new, higher energy machine, the document describes the possibilities, but no decision about such a thing is likely to be made until after results become available from seeing the LHC run at 13 TeV starting in 2015.
