The accurate and rapid identification of gravitational wave candidates is crucial for follow-up observations of electromagnetic emissions. In run O3, the LIGO/Virgo collaboration released 80 Open Public Alerts. However, the rates of retractions and false alarms point to the need for a complementary model that predicts the nature and origin of OPAs in low latency. I will discuss GWSkyNet, a machine-learning algorithm capable of discerning between signals of astrophysical and terrestrial origin.

Miniature, cold-cycle dilution refrigerators (DRs) are being explored as an alternative to adiabatic demagnetization refrigerators for the cooling of sensors aboard astrophysics balloon missions. In this talk, the design, function, and testing of a miniature, cold-cycle DR manufactured by Chase Cryogenics will be discussed. I will also briefly discuss our research on pulse tube refrigerators, which is part of an effort at NIST to minimize the size and infrastructure requirements of cryostats.

The Deep Underground Neutrino Experiment (DUNE) is a next-generation long baseline (1300 km) neutrino oscillation experiment. Neutrino beam measurements will be performed through near and far detectors. The far detector consists of four modules, installed 1,5 km deep underground, based on Liquid Argon Time Projection Chamber (LArTPC) technology to detect particles. In this talk I will discuss about the Signal and Power over fiber, being developed to operate at the Vertical Drift LArTPC.

Many BSM models predict new long-lived particles (LLPs) that could be produced at the LHC and travel measurable distances before decaying. This talk will focus on a background-free search for LLPs that aims to reconstruct decay vertices inside the CMS beam pipe using charged particle tracks, along with potential future extensions to the search. In addition, this talk will also present studies of silicon pixel sensors that will be installed in the upgraded CMS tracking detector for the HL-LHC.

This talk will review the use of Charge Coupled Devices (CCDs) in dark matter and neutrino experiments. In addition, it will discuss the Skipper-CCD technology (single-electron counting sensors), results of the ongoing Skipper-CCD experiments, and efforts to build OSCURA (an array of ~20,000 Skipper-CCDs for sub-GeV dark matter search).

This talk will review the local dark matter distribution of Milky Way-like galaxies extracted from state-of-the-art cosmological simulations, and its implications for dark matter direct detection. It will also discuss how the dark matter component of the Gaia radially anisotropic stellar population and the Large Magellanic Cloud can impact the results.

The NEWS-G direct dark matter search experiment uses spherical proportional counters (SPC) with light noble gases to explore low WIMP masses. The next phase of the experiment consists of a large 140 cm diameter SPC installed at SNOLAB. This talk will discuss several improvements of the detector, preliminary results of the last campaign, design and construction of the ECUME SPC, and the potential to achieve sensitivity reaching the neutrino floor in light dark matter searches.

Multi-messenger observations of cosmic rays, gamma rays, and neutrinos allow us to study the dynamics of high-energy particles in our Universe in unprecedented detail. This talk will present cases where multi-messenger observations have shown their strength, including the VHE gamma-ray flaring episode observed in the blazar TXS 0506+056 in coincidence with an IceCube neutrino event.

The LUX-ZEPLIN direct dark matter experiment uses a dual-phase time projection chamber to search for WIMP-nucleon scattering. The construction of the experiment was completed at SURF in 2021, with the first science run results in 2022. This talk will give an overview of the experiment and will explain the result from the first science run as well as what the future holds for the experiment.

The HeRALD experiment uses the unique properties of superfluid 4He to study dark matter-nucleon scattering in the sub-GeV mass range. This talk will show progress towards the observation of the quantum evaporation signal using an athermal phonon detector and will discuss HeRALD's R&D program with an emphasis on the helium and materials physics to refine the detector and push the nuclear recoil detection threshold as low as possible.

Seventy years after their invention, bubble chambers continue to prove useful for exploring the boundaries of our knowledge of particle physics. In this talk, I will present a short history of bubble chambers and motivation for their use in dark matter search experiments, then focus on challenges and successes of pushing them to lower nuclear recoil detection thresholds while maintaining control of backgrounds, and finally conclude with some projections for upcoming experiments.

Experimental neutrino physics has come a long way since the first detection of antineutrinos in 1956. Significant technical advancements (e.g. lower energy threshold, better energy resolution) have created unique opportunities for other fields of physics, such as nuclear physics. This talk shows how the thermal neutron capture (on proton) cross section was measured using the SNO+ detector. This measurement in SNO+ also paves the way to the first observation of antineutrinos in pure water.

Kai will discuss the current state of solar neutrino studies.

DEAP-3600 is a WIMP dark matter direct-detection experiment located deep underground at the SNOLAB facility (Sudbury, Canada) which uses liquid argon as the target material. This seminar presents data interpretations based on the first year of search.

SuperCDMS interleaved Z-sensitive Ionization and Phonon(iZIP) detectors have shown great success in discriminating electron recoils and nuclear recoils, while the High Voltage (HV) detectors have reached very low (~ a few eV) energy thresholds by sacrificing that discrimination. This talk focuses on a novel phonon-mediated two-stage silicon detector that retains both an excellent threshold performance of the HV detector and maintain the iZIP-style background discrimination.

The KOTO experiment located at the J-PARC research facility in Tokai, Japan aims to measure the branching ratio (BR) of the rare decay of the neutral kaon, KL→π0 νν. This talk will focus on the results of the 2016-2018 data set and the current status of the KOTO experiment.

This talk will discuss the way in which SuperCDMS sensitivity estimates are determined and how they rely on the ionization yield. This will lead into a discussion on SuperCDMS IMPACT, a neutron scattering experiment that aims to measure the ionization yield in silicon and germanium at sub-keV nuclear recoil energies.

In this talk, I will discuss the testing and qualification procedures for the modules and half cylinders of the CMS Phase I FPIX detector. I will also present a model-independent search for the production of heavy resonances decaying into top-antitop quark pairs with CMS Run II data.

Next-generation accelerator neutrino oscillation experiments such as DUNE aim to distinguish neutrino mass hierarchy and discover CP-violation. This talk will discuss the nuclear models used to interpret the DUNE data, allowing constraints to be set on the proton form factor.

This seminar will investigate the path taken to understand jet substructure and what this means for the future of measurements, searches, and reconstruction strategies for LHC Run 3, HL-LHC, and beyond.

Many theories of physics beyond the Standards Model (BSM) predict the existence of vector-like quarks (VLQs) - coloured fermions whose left- and right-handed components transform equally under the Standard Model gauge groups. I will discuss reinterpretations of recent ATLAS searches in the context of other BSM production processes.
