Many Already Reaping the Benefits of the Travel Voucher Program to CERN

Last FY the LPC initiated a policy of having a university co-convener and started the new “topological physics groups” to go beyond DPG and POG into Physics analyses. – 17 distinct universities have a convener

AB suggestion to enhance LPC WG leaders trips to CERN


LPC MeetingsLPC MeetingsLPC MeetingsLPC Meetings

LPC covers almost all topics in strength from DPG to POG to Topological groups ( 5 of). Visiting theorist just begun – a new initiative for the LPC.

LPC Forum – Food for LPC Forum – Food for ThoughtThought

LPC Forum – Food for LPC Forum – Food for ThoughtThought

Thanks to FNAL FRA – funds for pizza once a month prior to the LPC Physics Forum.

The aim is to give young physicists a chance to make a presentation in a “mentoring” environment prior to a talk at the full CMS collaboration.


LPC Support - IILPC Support - IILPC Support - IILPC Support - II

• Physics Support Group • Openings for CP (1 + 1 guest) filled this year• User desktop support – Patrick• Starter Kit/PAT launched this year

• ROC/DQM – RECO GR, Shifts ( second coordinator Nick)

• Gen/Sim – (second coordinator – Avto and Harry and Steve Mrenna) – Small Workshop this summer

• DPG/POG – new effort on tau (Anton and Alexei – tap into CDF/D0 expertise). Well integrated into CMS

• Increased US CMS university involvement in all LPC Working Groups


LPC Support - III LPC Support - III LPC Support - III LPC Support - III

In FY 2009 US-CMS hired 2 FTE of guest scientist support for physics analysis support

• Improved documentation

• Provide direct software and analysis support to users – all CMS Users, not LPC specific

• Development and deployment of analysis logging components

• Participate in Training and Tutorials

LPC now has more full time people performing user support than CMS at CERN


Mentors Program Web SiteMentors Program Web SiteMentors Program Web SiteMentors Program Web Site

www.uscmsmentors.org

Expand the engagement of US CMS senior physicists into active mentoring of US CMS GS and PD doing physics analyses. Tap into the US Tevatron and Physics expertise.


LPC Computing ResourcesLPC Computing ResourcesLPC Computing ResourcesLPC Computing Resources

CMS Center Computing Facilities (CAF)

• Unprecedented computing resources

• LPC hit the batch limit in August and by mid-September, a planned upgrade tripled the batch resources – in general, the computing group is one step ahead of potential bottlenecks

• Every US CMS collaborator can request 1TB of personal analysis space on the LPC cluster (just send request e-mail to Dan and Chris)

• Heartbeat of the physics effort of US CMS

• powerful computing resources is an inseparable part of LHC research

• University-based computing efforts (Tier-3) depend heavily on the FNAL-based experts (recent Tier-3 workshop hosted at Fermilab)


LPC Hosted WorkshopsLPC Hosted WorkshopsLPC Hosted WorkshopsLPC Hosted Workshops

• Workshops• First Physics, Oct. 07 – launched topo signature groups• JTerm II, Jan. 08 – GS + PD – rolled out starter kit• Run Plan, May 08 – plan from trigger to SM “standard candle”.

Roll out “GR Overlap” tool.• CMS 101++, June 08 – GS and PD tutorials• JTerm III, Jan 09 – roll out the US CMS Mentors program

• Launched 5 New “di-object” Signature Groups.• J+J• Gamma + X• l + l – ψ, Υ, W, Z• J + MET• L + J + MET – top pairs

• These groups are now fully functioning and doing early physics analyses. They are fully integrated into the CMS groups.

LPC has had many favorable comments from the “customers”. Report of the LPC Advisory Board taken on board and implemented.


Metrics – II, TTU Comment - Metrics – II, TTU Comment - 20092009

Metrics – II, TTU Comment - Metrics – II, TTU Comment - 20092009

Currently TTU has two PhD students, Chiyoung Jeong (working with Franks Chlebana on jet validation

and with Rob Harris on dijet resonance searches) and Youn Roh (working with Weimin Wu on VBF Higgs and with

Sunanda Banerjee on TB07 HE simulation), working at FNAL LPC.

They are also participating in the CMS detector commissioning at FNAL-ROC.

Initially TTU has decided to send them to LPC for 12 months, preparing the CMS physics analysis.

Recently we, Nural and myself, learn that they have made significant progress in their research works on CMS

and we would like to ask them to stay another year. Also they like very much to stay there to participate in

all aspects of CMS activities. This means we confirmed by ourself that LPC is the best place for our students

to learn CMS physics and to contribute their works on CMS experiment.

Metrics – III, BU Comments, Metrics – III, BU Comments, 20092009

I have a new postdoc starting today with BU - Edgar Carrera. I would like Edgar to be based at the LPC - at least for the next few months when he is making the transition to CMS and CMSSW. I had found the LPC particularly useful for jump-starting my own CMS effort and I'd like to hope that Edgar can also benefit from the expertise there.

How well is US CMS engaged in physics analysis? Metrics hard to specify. Well attended Workshops/Tutorials with a good sampling of US CMS groups. The LPC is reaching the US CMS community of 46 university groups, quite widely it seems.


Metrics – V, US CMS Metrics – V, US CMS MeetingsMeetings

Metrics – V, US CMS Metrics – V, US CMS MeetingsMeetings

Majority of US CMS INDICO meetings are hosted by the LPC. The weekly “All US CMS” meeting ties together CERN, LPC and the university groups. By this metric the LPC is vital to US CMS.


Metrics – VI, LPC CAF UsageMetrics – VI, LPC CAF UsageMetrics – VI, LPC CAF UsageMetrics – VI, LPC CAF Usage

There are ~ 1100 CAF accounts. About 400 different users logged on in the last 6 weeks. There is ~ 200 TB of quotaed disk for user data. There is also ~ 70 TB of scratch disk. There are now ~ 2000 batch slots, each hosting 1 job. Recall US CMS survey show 458 GS + PD + Faculty. LPC CAF serves US CMS well, it appears.

22 university WG leaders – LPC encourages WG leaders to attend all CMS Weeks – all Physics Weeks and all Physics Days.

Attendance is quite good since the above would be 3 + 2 + 2 = 7 trips. FY09 saw an increase

Next Steps - Soup to NutsNext Steps - Soup to Nuts Next Steps - Soup to NutsNext Steps - Soup to Nuts

• What - are all the needed steps to get to a validated standard candle and then right into a search mode?

• Who – is going to do each step , names !• When – does each step happen on the

sequence?• Where – does each step occur. Are the

resources available for each step? If not how do we start to plan/recruit for the missing parts?

• How – does the search get done in a timely way? The LHC is a discovery machine so how do we confront the discovery potential quickly, and correctly.

SummarySummarySummarySummary

• The LPC role is to enable and engage US physicists in the LHC physics to come (soon).

• By the available metrics the LPC seems to be performing adequately

• US CMS should take complete ownership of the LPC.

• The future evolution of the LPC which will be necessary to accommodate the coming “phase change” is in your hands. Join and shape.
