What is YPP?
MissionProvide young particle physicists with a forum in which to discuss the future of our field YPP has since grown
What is “young”?…has neither tenure nor other permanent position
Why the survey for our first project?Young people are less mobile, have limited means
Who is the consumer of this product?HEPAP subpanel, everyone

Balance vs. Focus
Can we sacrificepart of a physics program to get our next facility?
Redundancy costs money, but results are stronger if they are verified
Bread or circuses?

Balance vs. Focus 2
Promoting a particular mix of physicists is somewhat important
Astrophysics at HEP labs is somewhat supported

What is keeping you here?

Building the Field 2
Physicists think we are not retaining enough talent
plenty of grad students responded to the survey…
keep them by addressing these

Picking a Plan
What has most affected your current opinions of the options for the future of HEP?
1. Talking to colleagues
2. Current work
3. Workshops/conferences
4. Sitting and thinking

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)
Question #42 said:
“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).''

“Know enough”
“Unsure,” or “Don’t know enough”
A different cut: are you attending Snowmass?
“Do you know enough?”

Broad Conclusions
Young and tenured physicists have similar opinions
Differences based on continent of origin
Lack of security primary disadvantage to physics career
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%)
Survey wrap-up
Majority support for a linear collider if the option is waiting for “several years”
– If another option fits in the timeframe or– If a listed option is actually not viable in the timeframe
…then we should ask again.
Differences in preferred host country might make global cooperation difficult
commitment!
At the YPF town meeting (Snowmass), young physicists
seemed willing to join an effort if it began in another country
What next for YPP?
Survey data is available online,documentation released (short and long form), hope HEPAP finds it useful
Young Particle Physicists new chapters
New leadershipFlorencia Canelli interim rep for FNAL
Outreach to government, to the public,international issues, “young physicist” issuesAnother survey in a couple years?
