Meeting Summary:

John began the meeting reviewing news from the last conveners meeting (see slides).  >500 people have signed up for the workshop.  The introductory plenary talk will be given by Neal Weiner.  The summary plenary talk will be given by a convener (Rouven).

Rouven then reviewed the agenda, goals of the talks, discussion session, and poster session (see slides).  Four theory overview talks (35'+5') will be given, plus two shorter theory talks (15'+5').  They should be broad overview talks, with the theory and motivation behind the various particles.  The agenda is rather packed, so we will have to enforce strict time limits.  

There are three discussion sessions.  For the discussion sessions, 5 minute talk requests were made.  We had the following suggestions (please send corrections!):

Technology Section: (led by Tanner)  

-- Tanner:  Introduction

-- Lamm:   Magnet Technology

-- Carosi:  SC cavities/ New squid amps

-- Pivovara: IAXO x-ray detector needs

-- Mueller:   Alignment for LSW

Accelerator: (led by Arne Fryberger who will also give a talk)

-- Boyce: FEL developments (if not covered by Freyberger)

-- Batell: proton beam requirements

New Ideas: 

-- Graham:  Extending the range of HPS

-- Schuster: More signatures from the Hidden Sector

-- Zioutas:  WISPS in Space

-- Buckley: Probing leptophobic hidden photons with Project X

The Ideas Forum session should also be used to bring up general questions/ideas.  These include:

-- Holtrop: what can other groups (e.g. in astro) do to discover some of the particles?  Upadhye will include back-up slides to this effect. 

-- What can LHC do?

-- Sikivie:  New ideas and questions for the group.  This is a very good point, and we emphasize that contributions to the discussion session do not have to be in the form of 5-minute talks, but can be in the form of e.g. a question that raise a discussion.  

Echenard pointed out that there is not too much time for discussion.  It is true that the schedule is rather full, so we will enforce the time-limit for each talk.  We ask all speakers to adhere to the time limit.  On Thursday, there is a long discussion session that can, in principle, go until 7pm.  

Posters:  three posters were suggested so far (APEX, HPS, Hunting DM with NuSTAR and Axion Helioscope).  Others are welcome!  Please let us know asap.  Posters allow us to reach a wider audience.  

John suggested an outline of the written document (see slides).  Ringwald raised the issue that several experiments are sensitive to more than one type of particle.  It may make sense to have a theory summary/overview at the beginning where the various particles are discussed separately, followed by various experimental technique (e.g. light shining through a wall, electron-fixed-target experiments etc) with a discussion of existing experiments and what they can probe.  There will have to be cross-referencing.  We will devote some more thought to the outline. 

Any questions?  Let us know!  

See you next week at the workshop!
