Young Physicists Panel
What is YPP ?
Group of “young people” (have neither
tenure nor other permanent position)
Interested in furthering a positive future
for high energy physics
Address unique issues of young people
Formed in expectation of Snowmass
Survey
First project of zero-budget YPP should have
a good results-to-cost ratio …
Collect data about the issues of HEP from a
diverse group of physicists with varied career
stages, backgrounds, and research areas.
Survey should cover variety of questions
from
What is the most important physics for the field ?
to
Is it more important to be near your detector or your
advisor ?
Survey Implementation
Anonymous web-based survey
Mainly multiple choice questions
Space for comments
Soliciting participants
Coincide with first 2 weeks of Snowmass for
increased publicity
Online news, email distribution lists, paper
copies
Analysis
Survey responses converted to ntuples with
scripts and ROOT.
Demographics / BNL

Question #42: Pick a plan
We looked at the online material for timelines
(we took them at their word)
Few options could begin construction
within 3-5 years
“Committing” to a plan that takes longer
= waiting (we can change our minds)
Only listed items that preclude other options
($150M proton driver not listed)
What are the choices …
“If you had to choose from the following options, which
one would you pick:
A new e+e- collider (TESLA,NLC,CLIC) in the U.S. soon,
with continued research in VLHC, and muon storage
ring/muon collider technologies.
TESLA in Germany soon, with the goal of a post-LHC
higher energy VLHC in the U.S.
TESLA in Germany soon, with the goal of an eventual
muon storage ring/muon collider in the U.S.
Reserve judgment for several years, continue research.
Other (specify in the comments section).''
Choose one …

Broad Conclusions
Young and tenured physicists have similar
opinions
Continental divide …
Lack of permanent positions primary
disadvantage to physics career
Field is not doing enough outreach
Higgs/EWSB clear priorities  new facility,
but physicists prize a balanced program
Given the options we listed, total support for a
linear collider is strong (nearly 80%)
