Speaker: Aaron Mislivec, University of Minnesota
Subject: Neutrino-Nucleus Coherent Pion Production at MINERvA

Neutrino-nucleus coherent pion production is a rare neutrino scattering process that produces a lepton and pion in the forward direction while leaving the target nucleus in its initial state. Despite being rare, coherent pion production is an important background to neutrino oscillation measurements. Previous measurements of coherent pion production in the 1 to 10 GeV neutrino energy range, the energy range in which neutrino oscillation experiments operate, have been limited by either low statistics or detector capabilities. MINERvA, a dedicated neutrino-nucleus scattering experiment, has made precise measurements of neutrino and antineutrino charged current coherent pion production on carbon at 2 to 20 GeV neutrino energies. These measurements are an important input to neutrino-nucleus interaction models utilized by neutrino oscillation experiments.

Subject: The Sensitivity Frontier for Cryogenic Semiconductor Detectors

Cryogenic semiconductor particle detectors are undergoing revolutionary advancements that can greatly improve the reach of dark matter direct detection experiments. In order to fully realize the potential of these detector advancements, major challenges in ultra-low-energy calibration and device physics must be overcome. I will discuss techniques to use sub-keV energy deposits to bring the physics of detector response into sharper focus. Using the framework developed to study detector response at this level we will then muse about future devices with even more extraordinary capabilities.

Wednesday, November 8th 2017
Speaker: Zachary Lesko, University of Minnesota
Subject: Using The Drell–Yan process to test accuracy of simulated data sets.

Measurement of the transverse momentum (Qt) of the Z boson is useful for testing the accuracy of simulation software. The hadronization step, which simulates the QCD results of a proton proton collision, is a major potential beneficiary of this study . A highly accurate hadronization is vital for finding the mass of the other weak force carrier, the W boson. However the measurement of the Z's Qt is inaccurate at low values. I will discuss the use of the variable φ∗ which has a high correlation with the Qt of the Z boson

Wednesday, November 22nd 2017
Speaker: Hajime Muramatsu, University of Minnesota
Subject: Leptonic Decays of Charmed Mesons at BESIII

BESIII now holds the world's largest e+e- annihilation samples taken at Ecm = 3.773 and 4.178 GeV which produce copious charmed mesons, D0, D+, and Ds+. In this talk, I would like to report our on-going studies on D+ -> l nu and
Ds -> l nu (l = mu and tau). These allow us to determine the elements of the CKM matrix within the standard model, to test the unitarity of the second rows of the CKM matrix, probe lepton universality, as well as to calibrate the LQCD calculations of the decay constants, fD(s)+.

Wednesday, November 29th 2017
Speaker: Marvin Marshak, University of Minnesota
Subject: Neutrino Experiments at the Soudan Underground Laboratory

I will discuss the 38-year history of proton decay and neutrino experiments
at the Soudan Underground Laboratory, with a focus on the early history
of how and why the lab started and how it developed an extensive program
of physics experiments.
