Chris Tully CMS Physics and the LPC LHC Physics Center n Fermilab serves as the host lab for the US CMS collaboration u What are the functions of a host lab for remote collaboration? l Tailors to the research needs to the US community, leveraging the extensive resources of a national laboratory è US CMS physics community (48 institutions, ~440 PhD physicists and ~200 grad students) has a big footprint Only ~25-33% of this community is able to be CERN resident for extended periods. FNAL has the capacity to host a large fraction of the remaining community and especially that component that travels frequently for short-term visits (2-3 days) Fermilab hosts a core physics community composed of staff, RAs, Wilson fellows and visiting physicists and offers a wealth of resources including ROC shift facilities, video meeting rooms, offices and on-site housing è Unsurpassed computing and physics support group è Constant availability of topological and physics object working group representatives, detector and data monitoring experts It’s the guaranteed overlap with key people that makes short-term visits worthwhile è Effective launching ground for future CMS coordination positions and CERN-central responsibilities n Forging new ground in an era of international science participation l Learning how to provide what US physicists need to be effective in remote participation and to leverage the US investment in remote computing and university and lab-based expertise

Chris Tully CMS Physics and the LPC LHC Physics Center n Post-Puerto-Rico Center Improvements u Travel Voucher Program l 22 LPC University Coordinators given $5K travel funds to increase their CERN presence and participation in CMS physics efforts – has already made a noticeable impact on the level of connection between LPC working groups and the principal CERN-based analysis efforts u Mentor Program l Web Facebook of two dozen Senior US Physicists that have agreed to field questions and problems related to CMS physics analysis u J-Terms and Workshops l One week long CMS-specific tutorials, lectures and advanced topics l Upcoming Upgrades Workshop (Nov ) n Center Perception u CERN: strong, effective wing of the CMS physics effort u US groups: collab. resource for multi-institution physics analysis efforts u US community: as the place to go (and EVO) to stay in touch with the latest developments in detector/accelerator operation and fresh analyses Sep 25, 2008 Physics Coordination Meeting 4

Chris Tully CMS Physics and the LPC CERN presence n All US CMS Meetings u One year ago, 20 min. report on the status of detector and accelerator was added to the weekly meeting content l Slawek Tkaczyk and Jeff Spalding organize the reports l Experts, such as Jim Strait come for accelerator discussions l Provides a concise and revealing update for the whole community l Great highlight of the meeting! u Once this was a Fermilab-centric meeting, now the CERN-based participation is greater l Improved meeting time and place for CERN participation l Enhanced with local US CMS organizers l Snacks and Drinks l Serves as a weekly gathering place of US CMS people at CERN u Often covers hot topics in Global Run Analysis or future developments impacting physics analysis l Oct. 31 st talk on Physics Analysis Tools by Petar Maksimovic was excellent Sep 25, 2008 Physics Coordination Meeting 5

Chris Tully CMS Physics and the LPC Fermilab Participation in CMS Physics n Physics Support Group is one of the greatest assets of the LPC u Organized by Liz Sexton-Kennedy and Petar Maksimovic (JHU) u Keeps US on top of leading developments that impact and define how physics analysis is done on CMS u Core developers form the expert base that continues to command respect from the CMS community

Chris Tully CMS Physics and the LPC Fermilab Participation in CMS Physics n CMS Center Computing Facilities u Unprecedented computing resources l 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 u Heartbeat of the physics effort of US CMS l powerful computing resources is an inseparable part of LHC research u University-based computing efforts (Tier-3) depend heavily on the FNAL-based experts (recent Tier-3 workshop hosted at Fermilab)

Chris Tully CMS Physics and the LPC Non-factorizable Problem? Quotation from CMS Physics Meeting in September: “The direction we are moving: u Factorize the work leading to a physics result from CMS into two pieces: l Joint DPG-Physics meetings starting in end September (after CMS week). è The output of these are the physics objects of CMS. Electrons, jets, muons, etc. l Given these objects, explicit analyses (e.g. W cross section measurement) under the responsibility of the corresponding Physics Analysis group (EWK in this case) è PAGs will (have already…) launch(ed) explicit activity on each “paper” ” LPC topological groups do not factorize the problem.

Chris Tully CMS Physics and the LPC Summary Sep 25, 2008 n LHC Physics Center is actively serving the US CMS community u A number of improvements have been implemented, including a mentor program, a more in-depth J-Term and a wider range of workshop topics to broaden participation u Created a stronger CERN presence through a travel voucher program and better All US Meeting CERN-based arrangements u Physics coordination promotion record looks good and there is a general perception that the LPC is a good launching ground into the physics program n High-Energy Physics is more than eager to jump on new data from the LHC u Having the backing of Fermilab is a great strength to the US CMS program u The golden age of the LPC is likely to peak after the startup excitement has faded and the analysis work hits steady state operation with a large fraction of the US-based participation looking to the LPC as an alternative to frequent CERN travel Physics Coordination Meeting 19
