The LHC Physics Center (LPC)

1. The LHC Physics Center (LPC) Sarah Eno U Maryland ( for more information, see http://www.uscms.org/LPC/LPC.htm)

2. What is the LHC Physics Center? Located on the 11th floor of the FNAL high rise, the purpose of the LPC is to ensure the US gives the strongest possible assistance to international CMS in software preparations for Day 1. • a critical mass (clustering) of young people who are actively working on software (reconstruction, particle identification, physics analysis) in a single location (11th floor of the high rise), • a resource for University-based US CMS collaborators; a place to find expertise in their time zone, a place to visit with their software and analysis questions, • a brick-and-mortar location for US-based physics analysis, with such physical infrastructure as large meeting rooms, video conferencing, large scale computing, and a “water cooler” for informal discussions of physics.

3. MD Involvement in the LPC • Sarah Eno was co-founded (with Avi Yagil of FNAL) and is currently co-head of the LPC • Nick Hadley is in charge of coordinating our work in this spring’s comic slice test • Jeremy Mans (former MD postdoc) is in charge of the redesign of the calorimetry software for the new EDM

4. LPC is a reality, will continue to grow • Core of leaders is making it work • Advisory Board conducts reviews, provides written advice. • Lab management has committed real resources (space, bodies, workshop support). • CDF/D0 leadership understand why it’s a good thing. • LPC work is being well-integrated into CMS Physics Reconstruction and Selection (PRS). • Tevatron physicists are already having huge impact on CMS models for data, computing, and analysis.

7. Remote operations center Meeting rooms Room for 60 transients from Universities plus 60 permanent residents Transient space Resources: 11th Floor • Meeting Rooms/Video Conferencing/Internet • terminals/printers/office supplies • secretarial and computer support • Coffee machines/Water cooler Of the 60 permanent slots, 25% are University physicists. I expect 20 University-employed postdocs on the 11th floor full time by S06.

9. Past Year Highlights • Seven strong working groups! • Web presence • Remote Operations Center work started • 4 well-attended sessions of CMS 101, 4 successful Tevatron/LHC workshops, 4 well-attended sessions of “software tutorials”, tutorials on software tools • hosted for international CMS a “physics” week • theory/experiment brown bag lunch series, French lessons • 2-week mini summer school • a mini-workshop on LHC turn-on physics • weekly All USCMS meeting Fridays • 11th floor layout planned and constructed • successful review by Advisory Council, many successful external reviews

10. Web Information

11. 11th floor X-over Summer ‘05 Over 50 University-based physicists visited the LPC for at least 2 weeks this summer.

12. 11th Floor WH CERN HCAL Control Room HCAL Test beam Remote Operations Center: LHC@FNAL Erik Gottschalk: international coordinator, long term planning Kaori Maeshima: WH11 for test beam and cosmic ray test, next-few-year planning, work Virtually there, 24/7 http://home.fnal.gov/~eeg/remop.html

13. ROC • floor layout blueprint done • should be ready for commissioning right now!

14. Foundations (Samuel Riggs Alumni Center, UMD) Need to provide a firm foundation on which to build physics analysis

15. Foundations: Working Groups The Working Groups are the heart of the LPC. • provide an informal yet intense platform for work on the fundamental foundations of future LHC physics analysis • ensure that expertise in all areas necessary for a complete analysis can be found at the LPC • have been greeted with enthusiasm by international CMS and, by concentrating our efforts this way, have already been able to make substantial contributions to international CMS

16. Working Groups & US Universities • a postdoc who is stationed at FNAL working on both CMS and a Tevatron experiment can have a desk on the 11th floor and be near people from both experiments. • a CMS postdoc can be stationed at FNAL and benefit from having many people close by to interact with • a postdoc stationed at your university can come for a month, to get up to speed on analysis basics and to form personal connections that will help his/her later work • students can come for the summer to interact with a wide variety of experts and learn the basics on the CMS environment • Faculty can come every other week to keep their connections with the experimental community . • Faculty can come for a day for help with a particularly knotty software or analysis problem Participation in the groups will both help USCMS do physics and allow you to serve the US and International CMS communities

17. LPC Working Groups Each group has bi-weekly meetings with video conferencing. Each group has a well documented web page linked to the main LPC web page.

18. US University Involvement Simulation: FNAL, FSU, Kansas State, Kansas, Louisiana Tech, Maryland, Norhwestern, Notre Dame, Rutgers, UIC, Ciemat, Tata Jet/Met: FNAL, Rochester, MD, Rutgers, Boston, Cal Tech, Florida, Rockefeller, Princeton, Texas Tech, Iowa Muon: FNAL, Carnegie Mellon, Florida, Florida Tech, Nebraska, Purdue e/gamma: FNAL, northwestern, FSU, Minn, Kansas State, MD, Yale, Brown Tracking: FNAL, UIC, Nebraska, Riverside, UCSB, Louisiana Tech, Cornell, Davis, Wisconsin, Colorado Trigger: Wisconsin, Florida, Northwestern, FNAL, Vanderbilt, Texas A&M Offline/edm: FNAL, Cornell About 1/4 of the non-transient physicists on the 11th floor are University employees. All the (many) transients from Universities.

19. Plans for Coming Year Commissioning of ROC Physics group Cosmic slice test Full summer school Increased interaction with FNAL theory division

20. Cosmic Slice Test at LPC March 2006

21. Conclusions • The LPC is an essential part of US CMS’ strategy for doing physics analysis • The LPC has been embraced by the US CMS physics community • The LPC has had a substantial impact on both US and international CMS • The LPC provides a mechanism for contact to the theory community
