Ultralight axion-like particles are well-motivated dark matter candidates, emerging naturally from theories of physics at ultrahigh energies. We report the results of a direct search for the electromagnetic interaction of axion-like dark matter in the mass range that spans three decades from 12 peV...
Ultralight axion-like particles are well-motivated dark matter candidates introduced by theories beyond the standard model of particle physics. However, directly constraining their parameter space with laboratory experiments usually yields weaker limits
Hidden Photons (HPs) and Axion-like Particles (ALPs), which are respectively vector and pseudo-scalar realizations of bosonic super-WIMPs [2], are alternative candidates for DM with expected masses < 1 MeV/c2. A HP is the gauge boson of a hidden U(1) sector that kinetically mixes with ...
Absence of a significant source of lepton-flavor violation in the Standard Model (SM) provides a strong motivation for searching for LFV processes as any observable LFV signal must come from physics beyond SM (BSM). Axion-Like Particles (ALPs) are pseudo Nambu-Goldstone bosons that appear as ...

This system should open to CAST a window on possible detection of low energy Axion Like Particles emitted by the sun. Preliminary tests have involved a cooled photomultiplier tube coupled to the CAST magnet via a Galileian telescope and a switched 40 m long optical fiber. This system has ...
To investigate the sensitivity to new light particles atthe experiment, we consider models for axion-like particles (ALPs) and a lightscalar particle coupled to charged leptons. For both models, we show that thedetection sensitivity is almost an order of magnitude higher than other beamdump ...
Furthermore, we use this sensor to search for axion-like particles, setting stringent constraints on axion-like particles (ALPs) in the 4.5–15.5 Hz Compton-frequency range coupling to neutrons and protons, improving on previous limits by several-fold. This accelerated strategy has potential ...
