minutes of the Energy Frontier conveners' meeting June 20
THESE MINUTES CONTAIN HOMEWORK. PLEASE READ THEM THROUGH.
attending: Michael, Heather, Tom LeC., Rick van K, Sally, Ashutosh, Reinhardt,
Kaustubh, Meenakshi, Soeren, LianTao, Ken H., Robin, Sanjay, Jianming, Andrei,
Chris Tully, Joey H.
1. We discussed the schedule for the Seattle meeting. This is converging. In
the past couple of days, Michael received outline schedules from all of
your groups. Michael and Gordon will meet today to discuss and assign
rooms. To do this, we need the answers to the following questions:
1. Both NP and Higgs would like a session on extended Higgs particles
and searches for these. This should be a joint session, fitting
into 2 hours. The Higgs schedule is somewhat rigid, so Michael
proposes the time of Sunday 16:15 - 18:15. Can you make this
work?
2. Electroweak scheduled a session in parallel with the Cosmic and
Intensity frontier speakers. This was a mistake. They should
tell Michael where this session should be moved to.
Michael will get back to you soon about the room assignments and remote
connectivity. In the meantime, please fill in your agendas on the
Indico page.
2. You asked for guidance on the Sunday and Wednesday plenary talks.
Sunday, you should present the main conclusions of your report, in outline
form. You should present:
a. The overall conclusions of the report, especially any that will be
controversial
b. New perspectives that you have gained in the study (for example,
precision Higgs requires a full precision program that we will
map out in detail)
c How your results illuminate our four major questions:
i. Physics to be expected in this decade
ii. Physics case for High-Luminosity LHC
iii. Physics case for lepton collider Higgs factories
iv. Physics case for E > LHC facilities
>>> At Brookhaven, Chip and I asked you for a bulleted list of conclusions, ie
a summary of the above, by June 21. That is tomorrow. Please make a
few slides and send them to [log in to unmask] This list
is only the EF conveners and colloboration reps. We will discuss these
slides at next Thursday's phone meeting.
Wednesday, you should give a brief summary of what additional work is needed
or expected before Minnesota.
3. Sanjay Padhi gave a report on the hadron collider background generation. This
is done for 14 TeV and ready soon for 33, 100 TeV. Details are in the slides
that Sanjay sent to the snowmass-ef list. Please propagate these slides to
your working groups.
4. We discussed the structure of the Minnesota meeting. The outline of this
meeting is:
Monday -- plenary
Tuesday - Sunday frontiers in parallel in the mornings
cross-frontier activities in the afternoons
Monday, Tuesday concluding plenaries
Chip and Michael sent a proposed schedule of the EF morning activities:
Tuesday: plenary: summaries of the almost completed working group
reports
Wednesday: time for contributed papers. 10:30-12:00 we will schedule
plenary contributed talks from ATLAS and CMS, with
some time for other very important contributions
Thursday: plenary meeting with Instrumentation
This will be the only major EF + Inst F meeting of the
Snowmass process
Friday: meetings of the 6 working groups in parallel
Saturday: meetings of the 6 working groups in parallel
Sunday, end of day: EF plenary: previous and critique of the
summary talk
The comment was made that there were many people doing studies for Snowmass
who were expecting to present their work in Minnesota. It is possible to
change the schedule from the one sent previously so that we have 6 groups
in parallel on Friday and Saturday. But, this plus Wednesday is the only
time for presentations. Also, time for discussion is needed, and
Chip and Michael would like to meet with each group in turn on Saturday.
That is the reality, so please plan accordingly.
A new version of the Minnesota morning schedule is attached to this email.
Michael will send a new version of the Minnesota afternoon schedule when
it is available. We need to find good speakers who can address the
"tough questions" directed to energy frontier. We also need energy
frontier speakers for the sessions on dark matter and lepton and quark
flavor (to discuss direct searches for new particles) as well as the
colloquia on Higgs, Precision electroweak, and Energies beyond LHC.
5. We discussed the question: What if no new physics is seen by 2025? Can we
then ask for a higher-energy machine?
The first answer to this question is that it is very likely that new physics
will be seen by 2025. We have many excellent opportunities that we are
outlining in this report. Also, the ILC or other lepton-based precision
program will be just about to begin.
However, it is also important to have something to say for the case that
nothing is seen. We need to understand if a collider beyond LHC is
needed to:
a. Complete exclude the WIMP model of dark matter
b. Completely exclude the idea of naturalness or
mechanistic explanation of the Higgs vev energy scale.
Michael will circulate some notes on this; any other contributions will be
gratefully accepted.
Thanks to all !
