New Physics and New Proposal to Find Them in Proton Fixed-Target Facilities at Fermilab
Time: 3:30 pm - 4:30 pm
Place: 4274 Chamberlin Hall
Speaker: Yu-dai Tsai, FNAL
Abstract: We propose a dedicated search for minicharged particles (MCP) and light dark matter at Fermilab utilizing proton-fixed target facilities. First, we present the constraints and sensitivity reaches considering the MCP scattering with the electrons in the neutrino detectors, including SBND, MiniBooBE, MicroBooNE, DUNE, and SHiP [1]. Secondly, we present a new proposal, FerMINI, to place a new detector to further improve the sensitivity. The potential sites include the MINOS hall downstream of NuMI beamline and the proposed DUNE near detector hall along the LBNF beamline. The setup would drastically improve the sensitivity of MCPs in the MeV to GeV mass regime and will be discussed in detail in this talk. I will also talk about the searches of other weakly interacting particles, including light scalars, dark photons, and dipole portal heavy neutral leptons (an explanation of MiniBooNE anomaly) [2, 3] if time allows.

Supernova Cosmology Results from the Dark Energy Survey
Time: 12:00 pm - 1:00 pm
Place: 4274 Chamberlin Hall
Speaker: Richard Kessler, University of Chicago
Abstract: Roughly 9 months after the end of the 5-year transient search in the Dark Energy Survey (DES), DES submitted a series of papers describing its first cosmology results based on measuring cosmic distances for a small fraction of the Type Ia Supernova sample. I will give an overview of DES, our first results, and the analysis, highlighting where we have made improvements necessary to reduce uncertainties. I will also briefly describe future prospects for SN Ia cosmology with DES (full sample) and the WFIRST space mission.
