Wisconsin-Madisonhttp://www.physics.wisc.edu/groups/particle-theory/NPACTheoretical Nuclear, Particle, Astrophysics & CosmologyUW-Madison Workshop, October 2011
-
Workshop ImpetusDOE & 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 ?
-
BSM Landscape: HEP & NP LHC Challenges What we know now: high energy, astro/cosmo, low energy NP opportunities Open questions Workshop goals & agenda
-
Searching for Symmetries of the New SM:Complementary frontiers in the searchCollider experiments (pp, e+e-, etc) at higher energies (E >> MZ) High energy physicsParticle, nuclear & atomic physicsIndirect searches at lower energies (E < MZ) but high precisionUnique role for low energy studies in the LHC era

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

October 2011: The LandscapeWhat 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 ?

October 2011: The LandscapeWhat 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 ?
-
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
