New Physics and New Proposal to Find Them in Proton Fixed-Target Facilities at Fermilab
Date: Tuesday, November 27th
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.
