Ultralight bosons behave like coherent waves when the occupation number is large enough. If they are coupled to the Standard Model sector of the particle physics, such an oscillating background can induce a tiny signal. Near a fast rotating black hole, axion within one order of the mass window can accumulate through superradiance, with a large density saturating the non-linear self-interaction. If linearly polarized radiation is emitted near the black hole, axion can contribute to birefringence effect that shifts the position angle periodically, making the polarimetric measurements of the Event Horizon Telescope a powerful way to look for ultra-light axions. On the other hand, quantum metrology can play huge roles in the measurements of fundamental physics. Among these, resonant detection of axion dark matter based on electromagnetic coupling is a popular direction attracting many ongoing experiments and proposals such as microwave cavity, LC circuit and superconducting radio-frequency cavity. A quantum network of resonators can strongly enhance the signal power and boost the search. A network of spin dependent sensors with long baseline can identity the microscopic nature of dark matter or other cosmological background and increase the spatial resolution for transient source like axion or dark photon wave as well.

We investigate radiatively stable classes of pseudo-Nambu-Goldstone boson (pNGB) potentials for approximate spontaneously broken $\text{SO}(N+1)\to\text{SO}(N)$. Using both the one-loop effective action and symmetry, it is shown that a Gegenbauer polynomial potential is radiatively stable, being effectively an `eigenfunction' from a radiative perspective. In Gegenbauer pNGB models, one naturally and automatically obtains $ v \propto f/n $, where $ n \in 2 \mathbb{Z} $ is the order of the Gegenbauer polynomial. For a Gegenbauer Higgs boson, this breaks the usual correlation between Higgs coupling corrections and `$v/f$' tuning. Based on this, we argue that to conclusively determine whether or not the Higgs is a composite pNGB in scenarios with up to $\mathcal{O}(10\%)$ fine-tuning will require going beyond both the Higgs coupling precision and heavy resonance mass reach of the High-Luminosity LHC.

16:00 - 17:00
Despite countless searches at the LHC, there is still no evidence for new physics. The overwhelming majority of these searches are highly model-specific, motivated by (and optimized for) top-down considerations such as SUSY, extra dimensions, etc. This leaves a vast phase space unexplored by current searches. Could it be that we're not looking in the right places? In recent years, there has been growing interest in model-agnostic searches for new physics at the LHC, driven by powerful advances in modern machine learning, and many new methods have been proposed. I will give an overview of some of the exciting recent progress in this direction.

11:00 - 12:00
In this talk I will describe dark sectors made of non-abelian gauge theories with fermions neutral under the Standard Model. This leads to accidentally stable Dark Matter candidates that can be populated minimally through gravitational interactions. In the pure glue scenario DM is the lightest glueball while adding light fermions the lightest pion and baryon are the DM candidates. Despite the absence of SM interactions these scenarios are constrained by structure formation, Neff and limits on DM self-interactions.

Maximizing Direct Detection with HYPER Dark Matter
Gilly Elor
13:00 - 14:00
Faced with null results in the direct search of WIMP dark matter, there is growing motivation to explore dark matter candidates too light to be directly detected at current experiments. Indeed, there exists a vast array of proposals for direct detection experiments sensitive to sub-GeV dark matter coupled to nucleons. But can dark matter with a consistent cosmological history populate the regions of parameter space these proposals would be sensitive to? Furthermore, is there a maximum cross section for sub-GeV dark matter scattering off nucleons in light of present day constraints? In this talk, I will first estimate this maximum cross section. I will then introduce a novel dark matter candidate which realizes this cross section: HighlY interactive ParticlE Relics (HYPERs). The HYPER relic abundance is set by UV freeze-in, afterwhich a dark sector phase transition decreases the mass of the mediator which connects HYPERs to the visible sector. This increases the HYPER's direct detection cross section, but in such a way as to leave the HYPER's abundance unaffected. HYPERs present a benchmark for direct detection experiments that probe light dark matter.

Cosmological Relaxation through the Dark Axion Portal

11:00 - 12:00
The dark axion portal is a coupling of an axion-like particle to a dark photon kinetically mixed with the visible photon. I will demonstrate how this portal, when applied to the relaxion, can lead to cosmological relaxation of the weak scale using dark photon production. The key backreaction mechanism which triggers the trapping of the Higgs vev at the desired value involves the Schwinger effect: As long as electroweak symmetry is unbroken, Schwinger production of massless Standard Model fermions, which carry dark millicharges, suppresses the dark photon production. Once the electroweak symmetry is broken, the fermions acquire mass and the suppression is lifted. An enhanced dark photon dissipation then traps the relaxion at a naturally small weak scale. This model thus provides a novel link between the phenomenological dark axion portal, dark photons, and the hierarchy problem of the Higgs mass.

Kaon physics has played a tremendous role in the history of flavor physics and CP violation. In the past few decades, the B meson program has taken over as the main driving force for advancements in the field. I will discuss recent theoretical developments that have inspired a novel proposal for a next generation experiment for the detection of neutral kaon decays into charged particles. The proposed experiment would enable testing the SM CKM structure in a unique and critical way, by comparing the current knowledge from B-physics with clean measurements in K-physics. Moreover, rare kaon decays are among the most sensitive probes of both heavy and light new physics. I will present our work on these topics as well as the current status of the proposal.
