Hello EF Conveners,
We will have our first weekly EF Convener's phone call tomorrow, Thursday.
Energy Frontier Conveners' meeting
April 25: 11:00 PDT / 2:00 EDT
Contact information:
You call: domestic... (877)287-0283
international...(303)433-0165
participant code: 290-043
We will start the meeting promptly and end promptly after 1 hour.
Agenda items
1. How did Vidyo work for you at Brookhaven? What do you require from
the Seattle organizers?
2. We need to propose sessions of general interest for the
parallel-session days at Minnesota. Michael started a list below. Please
add to it. We've attached the first-pass block schedule discussed in
the Snowmass conveners' meeting last week.
3. We need to propose questions to the other frontiers. These should in
particular address issues that were not covered by the Cosmic Frontier's
list. Some examples are given below. Please add more. We'll read them
and briefly discuss them.
4. And, in turn we will devote time in these meetings to discussing how
we will respond to the questions to us from Cosmic Frontier and others.
Today, we will discuss the two questions below. For the moment, it would
be good to know if we are on track to answer these questions or, if not,
what studies are needed.
Thank you,
Chip and Michael

Titles for Sessions of General Interest at Minnesota:
1. Dark Matter -- attempt a perspective including all detection methods
including direct searches, and comparison of their reach (needs to be
organized with CF)
2. Lepton Flavor Violation -- what new physics models are accessed by
mu-e conversion, mu-> e gamma, and tau-> ell gamma experiments now being
planned? How are these compared to direct search capabilities? Can we
see lepton flavor violation at colliders? (needs to be organized with IF)
3. Future of the Higgs -- To what extent have we already ruled out
models of the Higgs field beyond the simple Standard Model. What are
examples of models that require precision measurements at different
levels? What should be the goal in precision Higgs measurement?
4. Instrumentation for High-Luminosity Hadron Colliders -- what are the
emerging technologies for confronting the problems of triggering, heavy
flavor ID, and precision measurement with high pileup? (needs to be
organized with Inst. F.)
-----------------------------------------------------------------------------
Pump-priming questions to other frontiers:
EF-IF1: We would like to understand the increase in sensitivity to new
particles in loops as a function of time for the g-2, mu-e conversion,
tau -> ell gamma, and EDM experiments. Can we plot this evolution along
with the evolution in sensitivity predicted for direct searches for new
particles at the LHC?
EF-InstF1: High luminosity running will depend on efficient triggering
in a difficult environment. Isolation requirements will likely be
compromised which may place a premium on tracking for lepton triggering.
What are the few most promising enabling technologies for
electron/photon/tau triggers in an environment, considering luminosities
up to 10^{35} cm^{-2}s^{-1}? What are likely R&D paths to realizing
these technologies?
EF-CF1: If dark matter has no SM interactions stronger than
gravitational, are there any prospects for discovering its particle nature?
[Daniel Whiteson also proposed the question:
EF-EF!: What is our best guess at the probability that a 33 TeV (100
TeV) pp machine will discover nothing new? [ note: this may be
unanswerable, but it's sort of the big elephant in the room ]
We think that this must be discussed in some way in our reports. Another
way to ask the question is, if there is no BSM physics at the HL-LHC,
what is the motivation to go to higher energy? ]
-------------------------------------------------------------------------------
Questions to us from the Cosmic Frontier, to be discussed today:
"HE1": • The message from the LHC seems to be that with data in hand, we
consistently outperform expectations for extraction of Higgs properties.
How much is there really for an ILC to contribute? What key assumptions
are we making now that we could relax with ILC inputs?
"HE2": • How much do we gain from searches for e.g.
triple-gauge-couplings in light of precision electroweak data? Is there
any kind of theory where we expect to naturally have SM-like precision
measurements, but large deviations in the TGCs?
