Fuzzy dark matter and the H_0 gravitational lensing measurement
Luca Teodori - Weizmann Institute of Science
Fuzzy dark matter can form cored density distributions, named solitons, at the center of galaxies. Such cores can be viewed as approximate mass sheets and can affect the time delay cosmography Hubble constant (H_0) measurement via the mass sheet degeneracy. We show that a subdominant component of… -
Saturons - VIRTUAL
Gia Dvali - Ludwig-Maximilians-Universität München (LMU)
“Saturons" are macroscopic objects that saturate the field theoretic upper bound on microstate degeneracy. Due to their maximal microstate entropy, from a quantum information perspective, saturons and black holes belong to the same universality class with common key properties. However, as opposed… -
Conformal Colliders Meet the LHC
Ian Moult - Yale University
Jets of hadrons produced at high-energy colliders provide experimental access to the dynamics of asymptotically free quarks and gluons and their confinement into hadrons. Motivated by recent developments in conformal field theory, we show that questions of interest in collider physics can be… -
On the cosmology and terrestrial signals of sexaquark dark matter
Marianne Moore - Massachusetts Institute of Technology (MIT)
The sexaquark, a hypothetical stable and neutral six-quark state, has been recently proposed as a dark matter candidate. Here, I argue it is very unlikely sexaquarks could consistently compose more than a billionth of the dark matter abundance for a wide range of scattering cross sections and… -
The cosmology of electron scalars
Zach Weiner - Perimeter Institute for Theoretical Physics
The cosmic microwave background is a sensitive probe of early-Universe physics, and yet fundamental constants at recombination can differ from their present-day values due to degeneracies in the standard cosmological model. Such scenarios have been invoked to reconcile discrepant measurements of the… -
Detecting Nanometer-Scale New Forces with Coherent Neutron Scattering
Zachary Bogorad - Stanford University
Significant effort has been devoted to searching for new fundamental forces of nature. At short length scales (below approximately 10 nm), many of the strongest experimental constraints come from neutron scattering from individual nuclei in gases. The leading experiments at longer length scales… -
The recent gravitational wave observation by pulsar timing arrays and primordial black holes: the importance of non-gaussianities - VIRTUAL
Antonio Iovino - Sapienza University of Rome
The recent data releases by multiple pulsar timing array (PTA) experiments show evidence for Hellings-Downs angular correlations indicating that the observed stochastic common spectrum can be interpreted as a stochastic gravitational wave background. We study whether the signal may originate from… -
What becomes of vortices when they grow giant?
Alexander Penin - University of Alberta
Quantum vortices are two-dimensional solitons which carry a topological charge - the first Chern number n. They play a crucial role in many physical concepts from cosmic strings to mirror symmetry and dualities of supersymmetric models. When n grows the vortices become giant. The giant vortices are… -
Dark Matter Search on Chips
Christina Gao - University of Illinois Urbana-Champaign
Axions and axion-like particles are well motivated candidates for dark matter (DM) and have a signature two photon vertex. The most sensitive axion DM search is at the gigahertz (GHz) regime. It relies on microwave cavities with high quality factors resonantly converting axion DM to cavity photons… -
The Cosmology of Dark Energy Radiation
Kim Berghaus - California Institute of Technology (Caltech)
If dark energy evolves in time its dynamical component could be dominated by a bath of dark radiation. Since dark energy was subdominant in the early universe, the dark energy radiation evades the usual stringent constraints on extra relativistic species from the cosmic microwave background… -
The Two Scales of New Physics in Higgs Couplings
Gabriele Rigo - CEA Saclay
Higgs coupling deviations from Standard Model predictions contain information about two scales of Nature: that of new physics responsible for the deviation, and the scale where new bosons must appear. The two can coincide, but they do not have to. The scale of new bosons can be calculated by going… -
QUEST-DMC: Direct Detection of Sub-GeV Dark Matter
Neda Darvishi - University of London
The QUEST-DMC experiment, aimed at detecting sub-GeV dark matter, utilizes a unique approach by employing superfluid Helium-3 (He-3) in conjunction with quantum sensors. Superfluid He-3 stands out as an ideal target medium for sub-GeV dark matter searches, especially in the context of spin-dependent…
