We explore the possibility of using superfluid helium for direct detection of sub-GeV dark matter (DM). We discuss the relevant phenomenology resulting from the scattering of an incident dark matter particle on a Helium nucleus. Rather than directly exciting quasi-particles, DM in this mass range will interact with a single He atom, triggering an atomic cascade which eventually also includes...

Dark matter is one of the most interesting fundamental puzzles of our universe. While we have accumulated sufficient cosmological evidence supporting its existence, the character of the dark matter particle is still unknown. A myriad of models have been proposed, the majority of which introduce a single dark matter candidate for simplicity. Though they provide testable hypotheses at various...

In the first part of this talk, I will estimate the maximum direct detection cross section for sub-GeV dark matter scattering off nucleons. For dark matter masses in the range of 10 keV − 100 MeV, cross sections greater than $10^{−36} - 10^{−30} \text{cm}^2$ seem implausible. I'll introduce a dark matter candidate which realizes this maximum cross section: HighlY interactive ParticlE Relics...

Although the dark matter direct detection experiments have advanced a lot to set very stringent bound on the GeV~TeV scale WIMP particles, the sub-GeV window is still open and waiting for further exploration. In addition to inventing new experimental probes, it is of more interest to extend the physics potential of existing direct detection experiments. I will provide two examples of achieving...

For the last few decades, High Energy Physics has been a victim of its own early success. Despite numerous theoretical arguments why it cannot be the final explanation for the interactions of fundamental particles, the Standard Model of particle physics continues to withstand intense scrutiny of the most determined experimental physicists. One promising way to search for signs of new physics...

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located several hundred meters from the ATLAS interaction point and shielded by concrete and rock, will host a suite of experiments to probe Standard...

FASER, the ForwArd Search ExpeRiment, is an LHC experiment located 480 m downstream of the ATLAS interaction point, along the beam collision axis. FASER and its sub-detector FASERnu have two physics goals: (1) to detect and study TeV-energy neutrinos, the most energetic neutrinos ever detected from a human-made source, and (2) to search for new light and very weakly-interacting particles....

We will present the status of the of milliQan Run 3 Detector that has been installed in PX56 at CERN LHC P5. The Run 3 detector is expected to enhance the sensitivity to the search of milli-charged particles [1], comparing to that from the milliQan demonstrator which had been taking data during year 2018 of the LHC Run 2 [2].
