  1. Beyond the Standard Model in Nuclear Physics M.J. Ramsey-Musolf Wisconsin-Madison NPAC Theoretical Nuclear, Particle, Astrophysics & Cosmology http://www.physics.wisc.edu/groups/particle-theory/ UW-Madison Workshop, October 2011

  2. Workshop Impetus • DOE & NSF: • What is the most effective program of NP experiments in fundamental symmetries & neutrinos? • How to evaluate impact of relatively small scale proposals that arrive piecemeal: what is the broader BSM context ? • NP Community: • What are the key scientific opportunities & open theoretical problems ? • How are LHC & astro affecting the landscape ?

  3. BSM Landscape: HEP & NP • LHC Challenges • What we know now: high energy, astro/cosmo, low energy • NP opportunities • Open questions • Workshop goals & agenda

  4. Bumps Deviations Large Hadron Collider Ultra cold neutrons CERN Searching for Symmetries of the New SM: Unique role for low energy studies in the LHC era Complementary frontiers in the search Collider experiments (pp, e+e-, etc) at higher energies (E >> MZ) Indirect searches at lower energies (E < MZ) but high precision Particle, nuclear & atomic physics High energy physics

  5. Collider Challenges: QCD Tevatron anomalies: W + jj G. Punzi, Blois ‘11 Close to 5 • BSM ? Leptophobic Z’, RPV SUSY,… • SM/QCD: tops? Subtraction of W + (n> 3) j ?

  6. Drell-Yan production of squarks Final state:2j + ET , 2j + l + ET St’d Model Backgrounds Jets + ET Collider Challenges: Superpartner Search

  7. Drell-Yan production of KK quarks Drell-Yan production of squarks UED • Additional challenges: • Determining spin • Determining SU(N) quantum numbers Final state:2j + ET , 2j + l + ET Final state:2j + ET , 2j + l + ET “LHC inverse problem” What complementary info from precision studies ? Collider Challenges:Other BSM Searches How to distinguish between scenarios ?

  16. October 2011: The Landscape What are the implications for BSM probes in nuclear physics ? • What question is the experimental program addressing? • What is the present and prospective impact on our knowledge of the new Standard Model ? • What sensitivity level is needed in order to compete with other probes addressing the same question ? • What are the primary, outstanding theoretical issues that must be addressed ?

  17. October 2011: The Landscape What are the implications for BSM probes in nuclear physics ? • For precision tests: what is the status of SM predictions ? (Impact of hadronic/nuclear matrix elements, solar modeling, cross section info…) • For rare/forebidden processes: what is the status of hadronic/nuclear input & how does it affect the BSM sensitivity ? • What are the relevant present and prospective BSM constraints from other sources ? • What is the interplay/complementarity with the LHC and cosmology ?

  18. Goals of this Workshop • Establish a framework for assessing the present and prospective impact of NP studies of fundamental symmetries and neutrinos on the search for the new SM & on our understanding of strongly interacting systems • Identify opportunities & challenges: open theoretical issues, needed advances in experimental sensitivity • Develop a plan for a written document (white paper? Review paper ?) and possibly living website • Identify and recruit colleagues (faculty, research staff, students, post-docs) into the process

  19. Workshop Agenda • Saturday: Informal topical review talks to set the stage for working group discussions • Sunday: Working group meetings • Monday am: Working group summaries and discussion of plan for future…
