Thank you for bringing this issue to us very explicitly.
Our hope was that the subgroup conveners would enunciate broad themes
for each area that justify accelerator-based experiments not only technically
but also at a gut level. The technical work is, in some sense, the raw
material for that discussion.
These should fit into the broad questions that Chip and I enunciated back
at the Fermilab meeting:
1. Where is the physics beyond the Standard Model? What are our
best ideas based on new information, especially from LHC ?
2. What is the physics case that motivates the LHC high-luminosity
upgrade?
3. Is there a physics case for a lepton collider Higgs factory?
4. Is there a case today for experiments at higher energy beyond LHC, e.g. 3 TeV
lepton colliders or 30-100 TeV hadron colliders?
We need to argue these things out technically, but also we need to articulate
the importance of our goals to the broadest scientific audience. Chip and
I are looking to the group conveners to bring not only the correct answers
but also the themes on which we will explain and argue for these answers.
In planning the panel discussion at the BNL meeting, Chip and I wanted to encourage
people at the meeting to think about optimistic scenarios in which the next
stage in exploration beyond the Standard Model would involve additional discoveries.
However, maybe this is too specific. You would like to discuss the broad themes
and the best answer to the broad questions at a more general level.
I would like to hear the opinions of the whole convener group on this point.
We will save time to discuss it on Monday.
Thank you,
Michael

Michael,
I will not be able to participate in the phone discussion, I will be on
the road.
However, I want to say that I believe, quite strongly, that we *must*
have a serious conversation about something similar to
the point 5, ideally instead of the panel discussion ``what if someone's
favorite model is discovered'' or even the status of BSM
(I think discussing these things is not very useful, quite frankly).
I believe we should discuss a reasonable set of broad and general
arguments that 1) can be turned into a strategy and 2) justify funding
for hep, without feeling
uneasy about these arguments at the first place ( I do feel uneasy
arguing that improving the measurement of a parameter x to a precision
y is
an absolutely crucial thing to do for figuring out how fundamental
physics works and I think this is not an argument that will be
received warmly;
by insisting on it, we may risk to loose credibility ).
Most of the BNL meeting will be spent in extremely detailed discussions,
it seems to me and I am afraid it will not help us figure out the best
strategy
for the field by the summer.
I think that having a frank high-level conversation about this issue
with leading hep-ph and hep-th figures will be very helpful.
Best regards,
Kirill
