Teaching and Learning Science with Learning Assistants
Andrew Ferstl
The science content classes for elementary education majors at Winona State University used Learning Assistants for the first time during the 2009 - 2010 academic year. Pre-post in…
Measuring the 2D Vector Aspect of Momentum Using Only One Dimension
Andrew Ferstl, Nathan Moore
Without the use of cameras to record 2D motion and an appropriate analysis tool, creating a laboratory activity for students to experience the vector nature of momentum can be chal…
Direct Detection of Dark Matter in the MSSM with Non-Universal Higgs Masses
J. Ellis, A. Ferstl, K. A. Olive +1
We calculate dark matter scattering rates in the minimal supersymmetric extension of the Standard Model (MSSM), allowing the soft supersymmetry-breaking masses of the Higgs multipl…
Supersymmetric Dark Matter Detection at Post-LEP Benchmark Points
John Ellis, Jonathan L. Feng, Andrew Ferstl +2
We review the prospects for discovering supersymmetric dark matter in a recently proposed set of post-LEP supersymmetric benchmark scenarios. We consider direct detection through s…
Constraints from Accelerator Experiments on the Elastic Scattering of CMSSM Dark Matter
John Ellis, Andrew Ferstl, Keith A. Olive
We explore the allowed ranges of cross sections for the elastic scattering of neutralinos χon nucleons in the constrained minimal supersymmetric extension of the Standard Model (CM…
Prospects for Detecting Supersymmetric Dark Matter at Post-LEP Benchmark Points
John Ellis, Jonathan L. Feng, Andrew Ferstl +2
A new set of supersymmetric benchmark scenarios has recently been proposed in the context of the constrained MSSM (CMSSM) with universal soft supersymmetry-breaking masses, taking…
Theoretical Aspects of Dark Matter Detection
John Ellis, Andrew Ferstl, Keith A. Olive
Direct and indirect dark matter detection relies on the scattering of the dark matter candidate on nucleons or nuclei. Here, attention is focused on dark matter candidates (neutral…
Exploration of Elastic Scattering Rates for Supersymmetric Dark Matter
John Ellis, A. Ferstl, K. A. Olive
We explore the possible cross sections for the elastic scattering of neutralinos chi on nucleons p,n in the minimal supersymmetric extension of the standard model (MSSM). Universal…
Gravitating Instantons In 3 Dimensions
Andrew Ferstl, Bayram Tekin, Victor Weir
We study the Einstein-Chern-Simons gravity coupled to Yang-Mills-Higgs theory in three dimensional Euclidean space with cosmological constant. The classical equations reduce to Bog…
Re-Evaluation of the Elastic Scattering of Supersymmetric Dark Matter
John Ellis, Andrew Ferstl, Keith A. Olive
We examine the cross sections for the elastic scattering of neutralinos on nucleons , as functions of in the constrained minimal supersymmetric standard model. We fi…
Variations of the Neutralino Elastic Cross-Section with CP Violating Phases
Toby Falk, Andrew Ferstl, Keith A. Olive
We analyze the neutralino-nucleus elastic cross-section in the MSSM, including contributions from CP-violating phases, using the four-fermi neutralino-quark interaction. Over a wid…
New Contributions to Neutralino Elastic Cross-sections from CP Violating Phases in the MSSM
Toby Falk, Andrew Ferstl, Keith A. Olive
We compute the four-Fermi neutralino-quark interaction Lagrangian including contributions from the CP violating phases in the MSSM. We find that neutralino-nucleus scattering cross…
