Where are Milky Way’s Hadronic PeVatrons?
Takahiro Sudo - Ohio State University
Observations indicate the existence of natural particle accelerators in the Milky Way, capable of producing PeV cosmic rays (“PeVatrons”). Observations also indicate the existence of extreme sources in the Milky Way, capable of producing gamma-ray radiations above 100 TeV. If these gamma-ray sources… -
Theory and Phenomenology of Continuous Spin Particles
Massless particles are always assumed to have Lorentz invariant helicity. However, the generic massless particles allowed by Lorentz invariance and quantum mechanics are "continuous spin particles," whose infinitely many discrete helicity states mix under little group transformations by an amount… -
An Effective Field Theory for Large Oscillons
Vasily Maslov - Lomonosov Moscow State University
Based on arXiv:2208.04334. We consider oscillons - localized, quasiperiodic, and extremely long-living classical solutions in models with real scalar fields. We develop their effective description in the limit of large size at finite field strength. Namely, we note that nonlinear long-range field… -
Dark Photon Stars
Edward Hardy - University of Liverpool
I will argue that many theories in which dark matter is light (with a mass < eV) lead to theoretically and observationally interesting dark matter substructure. As a particular, calculable, example I will show that this is the case for a new vector boson with non-zero mass (a `dark photon') that is… -
Studying new physics with nuclear spins
Will Terrano - Arizona State University
I will discuss the wide - range of new physics that can be probed with nuclear-spin comagnetometers, from EDM measurements to dark matter direct detection experiments. I will outline the potential for improvement in these measurements, and how improved quantum control could have a significant impact… -
GWs from high-quality axionic defects
Oriol Pujolas - New York University (NYU)
The axion solution to the strong CP problem has many virtues but it suffers from the so-called quality problem. This problem is avoided in heavy axion realizations which, however, are harder to probe experimentally. I will show how generic heavy axion models can be tested in current and future… -
Gauge Invariance and Finite Counterterms in Chiral Gauge Theories
Claudia Cornella - Johannes Gutenberg University Mainz
Any consistent regularization scheme induces an apparent violation of gauge invariance in non-anomalous chiral gauge theories. This violation shows up in perturbative calculations, and can be removed by including appropriate finite counterterms. In this talk I will discuss the derivation of such… -
Effective Theories and Applications of Stückelberg Vector Bosons
Graham Kribs - University of Oregon
New massive "dark" vector bosons are ubiquitous in BSM physics. I'll discuss the effective theories, interactions, and applications of theories with a (single) massive vector boson with a Stückelberg mass, with the goal of providing a clear and self-consistent approach to the (sometimes confusing)… -
Can Radio sky reveal primordial electron-proton interactions?
Maura Ramirez-Quezada - University of Sydney
The cosmic radio background (CRB) contains diffuse, discrete and cosmological emission sources from the universe. In this talk, I will discuss wether an additional contribution coming from low frequency photons is produced by free-free emission during the recombination era of the univers. These… -
MicroBooNE's First Results and the MiniBooNE Low Energy Excess
Nicholas Kamp - Massachusetts Institute of Technology (MIT)
In this talk, I will present MicroBooNE's first results probing the nature of the excess of low-energy interactions observed by the MiniBooNE collaboration. The talk will cover all four electron neutrino analyses that comprise MicroBooNE's first results, with a particular focus on the exclusive… -
Colliding light, tau g–2, and broadband axion detection
Jesse Liu - University of Cambridge
Muons are the archetypal ‘who ordered that?’ surprise discovered in cosmic rays and fittingly, recent muon measurements including g–2 could be challenging standard paradigms again. Remarkably, tau g–2 remains poorly constrained but can be 280 times more sensitive to new physics than the muon… -
Probing the Landscape of Heavy, Strongly Interacting, and Composite Dark Matter
Christopher Cappiello - Queen's University
Direct detection searches for dark matter are typically optimized to search for weakly interacting particles with masses on the ~GeV scale. But these experiments are, in principle, sensitive to masses as large as approximately the Planck mass, for cross sections much larger than typical Weak-scale…
