We report new constraints on the spin-dependent (SD) WIMP-proton cross section using the COSINE-100 experiment at the Yangyang Underground Laboratory. This analysis achieves a pioneering detection threshold of 3 and 4 pulse clusters corresponding to the measured photoelectrons. This allows us to access the unstudied few-photoelectron regime, significantly below the previous 8-photoelectron...
The search for neutrinoless double electron capture (0ν2EC) is a powerful probe for lepton-number violation and the Majorana nature of neutrinos. We report on a search for the 0ν2EC decay of 40Ca using the AMoRE-I cryogenic detector array, which utilizes metallic magnetic calorimeters (MMCs) and 48depl.Ca100MoO4 crystals. Analyzing a total...
Dark matter (DM) can be gravitationally captured around a massive compact object, forming a dense halo. If primordial black holes (PBHs) exist, surrounding dark matter particles can be accreted through gravitational attraction, leading to the formation of a DM halo with a steep spike profile near the PBH.
If the dark matter consists of axions or axion-like particles (ALPs), the high number...
