One Event, Two Frontiers: From LZ to LHC
Md Sadique Anwar, Nivedita Ghosh, Sahabub Jahedi +1
The 248 keV nuclear-recoil event observed by the LUX-ZEPLIN (LZ) experiment could potentially arise from dark matter (DM) interactions with nucleons. We investigate elastic scatter…
LUX-ZEPLIN's Stairway to Heaen: limits on elastic scatters of dark matter from solar capture
Debajit Bose, Akash Kumar Saha, Thong T. Q. Nguyen +3
The recent report of xenon recoiling with about 250 keV energy at the LUX-ZEPLIN (LZ) dark matter direct detection experiment was interpreted by the collaboration as either a momen…
Dive deeper with SUBMARINE: SUB-Mev dArk matter diRect detectIon using bilayer grapheNE
Rinchen Sherpa, Anuvab Sarkar, Tarak Nath Maity +3
Novel target materials with anisotropic response will play a key role in detecting low-mass dark matter in upcoming experiments. Bilayer graphene is one such material that has been…
LHAASO Galactic Plane -rays Strongly Constrain Heavy Dark Matter
Celine Boehm, Ranjan Laha, Tarak Nath Maity
LHAASO, a ground-based observatory, is unveiling new frontiers in our understanding of high-energy rays and cosmic rays. It has recently observed high energy diffuse rays f…
limits from Super-Kamiokande on dark matter-electron scattering in the Sun
Dhashin Krishna, Rinchen Sherpa, Akash Kumar Saha +3
Particle dark matter scattering on electrons in the Sun may gravitationally capture and self-annihilate inside it to neutrinos and anti-neutrinos, or other final states that in tur…
Neutrinos as background and signal in searches using the Migdal effect
Tarak Nath Maity
Ionization or excitation resulting from the noninstantaneous response of the electron cloud to nuclear recoil is known as the Migdal effect. Dark matter searches utilizing this pro…

Tarak Nath Maity, Celine Boehm
Current ton-scale dark matter direct detection experiments have reached an important milestone with the detection of solar neutrinos. In this paper, we show that these data can be…
The neutrino fog for dark matter-electron scattering experiments
Ben Carew, Ashlee R. Caddell, Tarak Nath Maity +1
The search for sub-GeV dark matter via scattering on electrons has ramped up in the last few years. Like in the case of dark matter scattering on nuclei, electron-recoil-based sear…
Neutrinos from the Sun can discover dark matter-electron scattering
Tarak Nath Maity, Akash Kumar Saha, Sagnik Mondal +1
We probe dark matter-electron scattering using high-energy neutrino observations from the Sun. Dark matter (DM) interacting with electrons can get captured inside the Sun. These ca…
Cosmic-ray boosted dark matter in Xe-based direct detection experiments

LUX-ZEPLIN (LZ) collaboration has achieved the strongest constraint on weak-scale dark matter (DM)-nucleon spin-independent (SI) scattering cross section in a large region of param…
Dark matter substructures affect dark matter-electron scattering in xenon-based direct detection experiments
Tarak Nath Maity, Ranjan Laha
Recent sky surveys have discovered a large number of stellar substructures. It is highly likely that there are dark matter (DM) counterparts to these stellar substructures. We exam…
