Seeing into the immediate post-merger environment of a neutron star collision
Aaron Tohuvavohu - University of Toronto
The rich EM phenomenology in the seconds, minutes, and hours just before, during, and after a compact object merger encodes the magnetization of the binary components, the nature of the post-merger remnant, the neutron star equation of state, the free neutron abundance, and a wide array of other… -
The Callan Rubakov Effect
The Callan Rubakov Effect describes the interaction between (massless) fermions and a smooth monopole in 4d gauge theory. In this scenario, the fermions can probe the UV physics inside the monopole core which leads to interesting effects such as proton decay in GUT models. However, the monopole… -
The entanglement of quantum computing and dark matter searches
Jeter Hall - SNOLAB
SNOLAB is a laboratory two kilometers underground in Sudbury, Ontario, Canada. This laboratory boasts the lowest muon flux on Earth. This low muon flux is utilized for a variety of research on Quantum computing and the nature of dark matter, which are some of the highest priority research topics in… -
New probes of ultrahigh energy cosmic ray source evolution
Marco Muzio - Pennsylvania State University
Despite first observing cosmic rays with energies above an EeV (10^18 eV) in the 1960s, the source of these particles remains an open question. Modern observatories, in particular the Pierre Auger Observatory and Telescope Array, have firmly established that the cosmic ray spectrum continues up to… -
Two loops and Higgs field space geometries; pushing the interpretation of LHC data forward in the SMEFT
Getting the strongest physics conclusions from collider particle physics experiments regarding the (in)consistency of the Standard Model with actual measurements requires Effective Field Theory techniques. This approach (known as the SMEFT) has been rapidly advanced in recent years, leading to new… -
Relativistic superfluids, and the connection between finite density and spontaneous symmetry breaking for interacting scalar fields
Alessandro Podo - Columbia University
We study the low-energy effective action for relativistic superfluids obtained by integrating out the heavy fields of a UV theory. A careful renormalization procedure is required if one is interested in deriving the EFT to all orders in the light fields (at a fixed order of derivatives per field)… -
MeV Sterile Neutrinos in Light of the Cabibbo-Angle Anomaly
Kohsaku Tobioka - Florida State University
The mixing angles of the quark sectors are constrained by unitarity in the standard model. However, recent data indicates a about 3 sigma deviation from unitarity in the mixing angle between the 1st and 2nd generation down-type quarks, known as the Cabibbo angle anomaly. The observations include the… -
Polarized Signatures of Axions at Magnetic White Dwarfs
Christopher Dessert - New York University (NYU)
I will discuss a novel search for axions using spectropolarimetric observations of magnetic white dwarfs (MWDs). Photons produced as thermal radiation at the MWD surface may convert into an axion as they traverse the magnetosphere, but only the component polarized parallel to the MWD magnetic field… -
Cosmology and Unification
Raman Sundrum - University of Maryland, College Park
Precision measurements of primordial correlators in the CMB, Large Scale Structure, and 21-cm cosmology may contain “on-shell" imprints of extremely heavy particle physics, with masses comparable to the inflationary Hubble scale, via the remarkable inflationary mechanism known as “cosmological… -
The Pacific Ocean Neutrino Experiment
Matthias Danninger - Simon Fraser University (SFU)
Every time researchers have pushed the energy boundary in particle physics we have found something new about our Universe. Recently, IceCube has demonstrated that Neutrino Telescopes can use neutrinos from the cosmos as excellent tools to continue this exploration. The true potential of this field… -
Observing sub-nanohertz gravitational waves with pulsar parameter drift
William DeRocco - University of Maryland, College Park
Gravitational waves with frequencies below 1 nHz are notoriously difficult to detect. With periods exceeding current experimental lifetimes, they induce slow drifts in observables rather than periodic correlations. Observables with well-known intrinsic contributions provide a means to probe this… -
Bridging gaps in the spectrum of GWs: new opportunities for fundamental physics.
Diego Blas - Universitat Autònoma de Barcelona
In this talk I’ll highlight the existence of gaps in the spectrum of GWs poorly explored by current observations and that may contain information about BSM physics or primordial cosmology. I’ll focus on the muHz gap, and explain how to use the resonance absorption of GWs by binary systems (as the…
