Constraints on dark matter-nucleon effective couplings in the presence of kinematically distinct halo substructures using the DEAP-3600 detector
DEAP-3600 is a WIMP dark matter direct-detection experiment located deep underground at the SNOLAB facility (Sudbury, Canada) which uses liquid argon as the target material. This seminar presents data interpretations based on the first year of search.

Hybrid Detector: The High Voltage detector with background rejection
SuperCDMS interleaved Z-sensitive Ionization and Phonon(iZIP) detectors have shown great success in discriminating electron recoils and nuclear recoils, while the High Voltage (HV) detectors have reached very low (~ a few eV) energy thresholds by sacrificing that discrimination. This talk focuses on a novel phonon-mediated two-stage silicon detector that retains both an excellent threshold performance of the HV detector and maintain the iZIP-style background discrimination.

Search for the Rare Decay of the Kaon, KL→π0 νν
The KOTO experiment located at the J-PARC research facility in Tokai, Japan aims to measure the branching ratio (BR) of the rare decay of the neutral kaon, KL→π0 νν. This talk will focus on the results of the 2016-2018 data set and the current status of the KOTO experiment.

SuperCDMS IMPACT: The Importance and Determination of the Silicon Ionization Yield
This talk will discuss the way in which SuperCDMS sensitivity estimates are determined and how they rely on the ionization yield. This will lead into a discussion on SuperCDMS IMPACT, a neutron scattering experiment that aims to measure the ionization yield in silicon and germanium at sub-keV nuclear recoil energies.

CMS FPIX Phase I Upgrade & Search for ttbar Resonances in Boosted Semileptonic Final States
In this talk, I will discuss the testing and qualification procedures for the modules and half cylinders of the CMS Phase I FPIX detector. I will also present a model-independent search for the production of heavy resonances decaying into top-antitop quark pairs with CMS Run II data.

Investigating nuclear modeling and progress in measuring the CCQE cross section on hydrogen in MINERvA
Next-generation accelerator neutrino oscillation experiments such as DUNE aim to distinguish neutrino mass hierarchy and discover CP-violation. This talk will discuss the nuclear models used to interpret the DUNE data, allowing constraints to be set on the proton form factor.
