Chaos & Complex Systems Seminar
Solar activity and its influence on us
Time: 12:05 pm - 1:00 pm
Place: 4274 Chamberlin (Refreshments will be served)
Speaker: Alex Lazarian, UW Department of Astronomy
Abstract: The Sun is a magnetically active star. Solar activity results in inducing the solar wind as well as generating the energetic particles. The solar wind affects the size of the heliosphere around the solar system and this induces modulation of the galactic cosmic rays arriving to the Earth. Energetic particles from the Sun interact with the Earth's magnetic field and cause electromagnetic storms. I shall discuss how the Sun affects the Earth ecosystem.

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.
