Session O: Fixed target / Dark sectors / Applications outside particle physics

Oral presentation using Zoom

Recent direct detection experiments put the strong constraint on WIMPs at the electroweak scale, and people have started focusing on light DM scenario. For the light thermal scalar DM, it is usually constrained by the CMB observation because it annihilate at s-wave. Despite of CMB constraint, We have revealed that some parameter regions are still surviving for the model with singlet scalar...

Session O: Fixed target / Dark sectors / Applications outside particle physics

Oral presentation using Zoom

We discuss the prospect of detecting new gauge bosons (like the dark photon and leptophilic gauge bosons) using the ILC beam dump, assuming that muon shield, veto counter, and particle detector are installed behind the beam dump. Because the $e^{\pm }$ beams are dumped after each collision at the ILC, a large number of electrons and positrons are available for the beam dump experiment. If a new...

104. Probing Dark Sectors With Invisible Vector Meson Decays

Session O: Fixed target / Dark sectors / Applications outside particle physics

Oral presentation using Zoom

Fixed target experiments such as NA64 and LDMX use missing energy-momentum to detect the production of dark matter and other long-lived states. The most studied production mechanism is dark Bremsstrahlung through a vector mediator. In this work, we explore a complementary source of missing energy-momentum signals: Bremsstrahlung photons can convert to hard vector mesons in exclusive...
