  1. Toward the End of PhD Career at the LPC: How does the LPC help me grow as a student and beyond? • 17th July 2014 LPC10 Mini-Symposium TutanonSinthuprasith Brown University

  2. Introduction • About myself: • PhD Candidate at Brown University • PhD career path • Brown University CERN the LHC Physics Center (LPC)

  3. PhD Career Path • CERN • Service: Hadronic Calorimeter • L1 Trigger • Hcal Data Validation • Hcal Operation • Analyses: • New physics in 4-jet final state: not published (superseded) • New physics in 8-jet final state (main contribution, also at the LPC) • Microscopic blackhole (partial contribution, also at the LPC)

  4. PhD Career Path • LPC • Offline data certification shift supervisor at LPC ROC • Analyses • New physics in 8-jet final state at 7 TeV(main contribution, EXO-11-075 PAS publication) • Microscopic blackhole (partial contribution, JHEP 04 (2012) 061, JHEP 07 (2013) 178 led by AlexeyFerapotov, LPC Distinguished Researcher) • New physics in 8- and 10-jet final state at 8 TeV (lead the analysis, EXO-13-001, Pre-approval stage)

  5. Brown University and the LPC • Brown’s history with the LPC: • Brown joined CMS in 2004 and has had a close collaboration with the LPC since then • Leadership • Current LPC co-cooridnator: MeenakshiNarain • Current LPC management board: Greg Landsberg • Current ToTW co-chair: AlexeyFerap`ontov • Past CMS/US CMS physics coordinator: Greg Landsberg • Past LPC Trigger group convener: Greg Landsberg • Past LPC Physics Forum co-chair: Greg Landsberg • Past LPCdileptonconvener:MeenakshiNarain • Past LPC management board and selection committee: Greg Landsberg • Past CMS statistical committee: Ulrich Heintz, GenaKukartsov • Past CMS statistics/analysis tools: GenaKukartsov • Past Jet/MET Trigger convener: ShabnamJabeen • Past ToTWco-chair: John Paul Chou • Recognition • LPC Senior/Junior Distinguished Researchers (LPC-DR) • Currently affiliated with Brown: Greg Landsberg (2014), MeenakshiNarain (2012), AlexeyFerapontov (2012/2014) • Affiliated with Brown in the past: GenaKukartsev (2012), John Paul Chou (2011), Aram Avetisyan (2013), ShabnamJabeen (2012) • Awardees for LPC Guests & Visitor Program: SinanSagir, Alex Garabedian, Joshua Swanson

  6. Brown University and the LPC • Brown’s history with the LPC: • The LPC and Brown have been collaborating on both detector and performances, and physics analyses. Here is the selected short list in the area, in which the LPC directly or indirectly helps us achieve our goals. • Detector and performance • Silicon Tracker • Hadron Calorimeter and Trigger • Tracking and Trigger Performance • Jet/MET Physics Object • b-Tagging Algorithm Development • MC simulation • Researches and topics of interest • Top quark physics and electroweak interaction • New physics: • Heavy gauge boson W’ Z’ • Fourth generation quarks/Vector-like quarks • Extra dimension • Multijet final states: Blackhole, Axigluon/Coloron, RPV SUSY • Long-lived particle, delayed muons • Stealth SUSY • …

  7. The LHC Physics Center • How does LPC help me grow as a PhD student in high energy physics? • LPC: Learning Center: • Hands-on Tutorials – Stats/Jet substructure • Analysis School LPC: Physics Discussions/Comments/Reviews: Theorists/Conveners/ARC Physics Analyses Publications • LPC: New analyses ideas and/or techniques are initiated and developed: • Topic of the Week - RPV SUSY. Accidental Substructure • Physics Forum • LPC: Computing Help Desks/Users Facility: • Storage space and LPC computer clusters/lpc-howto • Minor technical problems – lpc-howto, talk to people

  8. Physics Outputs Search for New Physics in 8- and 10-jet Analysis at 8 TeV Search for New Physics in 8-jet final state at 7 TeV Preliminary EXO-11-075 EXO-13-001

  9. Summary • As a PhD student who stationed at the LPC, I greatly benefited from: • 1. A thorough aspects of physics analysis ranges from • Initial state of learning physics and what tools to be utilized • hands-on tutorial (HATS) • initiate the ideas/techniques (Topics of the Weeks/Physics Forums/Seminars/Workshops) • discuss the plausibility/goal of the analysis with leading theorists • Analyzing – final state of the analysis • utilize LPC storage space, and LPC computer cluster • take advantage of available expertise at the LPC • discuss about and obtain comments on physics results, strengths and weaknesses of the analysis, etc from conveners/ARC/theorists at LPC

  10. Summary • 2. An atmosphere which encourages us to work and deliver the results in a timely manner. • 3. A sense of particle physics community at the LPC • As a physicist and beyond, I greatly benefited from: • 1. A bigger picture of particle physics and cosmology in general – not limited to LHC physics • 2. Where we, as a whole community, stand, and in which direction we are progressing towards. And where I am standing • 3. What other factors that we need to consider beside physics in large organization, e.g., budget trends, connections, jobs in the field. • 4. Broaden my horizon: perspectives from graduate student fellows, postdocs, scientists and faculties

  12. The LHC Physics Center Analyses’ ideas and techniques Learning Center LPC offers sequences of important learning sessions in both physics and the “tools” to carry on the physics analyses • LPC is a hub for physics discussions with experimental experts as well as leading theorists • Tools • CMS Data Analysis Schools • CMS Hands-on Tutorial Sessions (HATS): • Jet substructure HATS • Statistics HATS • FNAL Software School (broader community to be held in August) • Many seminars/workshops: • Introduction to advanced statistics for CMS Analyzers • CTEQ&LPC workshop • SUSY at the near frontier • LPC Topic of the Week • “LHC searches examined via the RPV MSSM: Gluinos”,Evgeny Kats/Jared Evans • “Toward Full LHC Coverage of Natural Suspersymmetry” arXiv:1310.5758v1 • “Jet substructure by accident”, Tim Cohen • “Jet substructure by accident” arXiv:1212.1456 • LPC Physics Forum • Private discussions

  13. The LHC Physics Center Computing Help Desk and Users Facility • Minor technical problems: • lpc-howtomailing list, e.g., missing data/transfer samples/minor computing glitches/jobs submissions • Talk to experts in person at the LPC • LPC facility: • Storage space allocation for analyses’ groups and projects (lpcmj) • 8- and 10-jet analysis has all samples (including high jet multiplicity background) privately produced and stored at the LPC • Private Physics Discussion/Comments/Reviews: • Fruitful discussions and advices from experts • Closely reviewed by EXO Convener (John Paul Chou) • Suggestions from pythia author (Stephen Mrenna) • Analysis Review Committee (Robert Harris) Physics Discussions/Comments/Reviews
