Not so good s for Higgsino dark matter as LZ excess: stringent limits from Super-Kamiokande and IceCube
Debajit Bose, Akash Kumar Saha, Deep Jyoti Das +9
The LUX-ZEPLIN (LZ) collaboration has recently reported a single nuclear recoil event at a high recoil energy of about 250 keV. This has been interpreted as inelastic scattering of…

Direct detection of electromagnetically interacting ultraheavy dark matter
Jason Kumar, Biprajit Mondal, Girish Muralidhara +1
At a level too faint for astronomy, particle dark matter may interact with Standard Model states via the photon. We derive limits from direct detection experiments on photon-mediat…

The neutrino roof: Single-scatter ceilings in dark matter direct detection
Nirmal Raj, Biprajit Mondal
We identify the maximum cross sections probed by single-scatter ``WIMP" searches in dark matter direct detection. Due to Poisson fluctuations in scatter multiplicity, these ceiling…
