Constraining Ultralight Scalars with Black Hole Binary Mergers in Galactic Nuclei
Majed Khalaf, Eric Kuflik, Alessandro Lenoci +2
Ultralight scalars can form long-lived, macroscopic bound states around spinning black holes, known as superradiance clouds. These clouds provide an additional channel for energy d…
Analytical Fluxes from Generic Schwarzschild Geodesics
Majed Khalaf, Chris Kavanagh, Ofri Telem
We present an analytic method for computing gravitational-wave fluxes from bound Schwarzschild geodesics with arbitrary eccentricity. Our approach systematically expands the Fourie…
Dissipative Losses In Black Hole-Induced Vacuum Decay
Michael Geller, Ofri Telem
We address the long-standing puzzle of false vacuum decay catalyzed by black holes. Naively, small black holes with large Hawking temperatures can generate highly-boosted true vacu…
Non-Abelian and Type-A Conformal Anomalies from Euler Descent
Gleb Aminov, Csaba Csáki, Ofri Telem +1
We classify the non-Abelian anomaly of the Euclidean conformal group in dimensions via Stora-Zumino descent from its Euler invariant polynomial in dimensio…
Phase Transitions at Unusual Values of
Csaba Csáki, Teruhiko Kawano, Hitoshi Murayama +1
We calculate the dependence in a cousin of QCD, where the vacuum structure can be analyzed exactly. The theory is gauge theory with flavor…
Bound-Unbound Universality and the All-Order Semi-Classical Wave Function in Schwarzschild
Majed Khalaf, Chia-Hsien Shen, Ofri Telem
We present a systematic method for analytically computing time-dependent observables for a relativistic probe particle in Coulomb and Schwarzschild backgrounds. The method generate…
The Seiberg-Witten Axion
Csaba Csáki, Rotem Ovadia, Maximilian Ruhdorfer +2
We present a fully calculable UV complete toy model of a Peccei-Quinn (PQ) axion coupled to magnetic monopoles as well as electric charges. The theory has manifest electric-magneti…
Abelian Instantons and Monopole Scattering
Csaba Csáki, Rotem Ovadia, Ofri Telem +2
It is usually assumed that instantons can only arise in non-Abelian theories. In this paper we re-examine this conventional wisdom by explicitly constructing instantons in an…
The Quantum Spectral Method: From Atomic Orbitals to Classical Self-Force
Majed Khalaf, Ofri Telem
Can classical systems be described analytically at all orders in their interaction strength? For periodic and approximately periodic systems, the answer is yes, as we show in this…
Partially Celestial States and Their Scattering Amplitudes
Csaba Csaki, Ofri Telem, John Terning
We study representations of the Poincaré group that have a privileged transformation law along a p-dimensional hyperplane, and uncover their associated spinor helicity variables in…
A Guide to AMSB QCD
Csaba Csáki, Andrew Gomes, Hitoshi Murayama +3
We present a careful study of the chiral symmetry breaking minima and the baryonic directions in supersymmetric QCD ( with flavors) perturbed by Anomaly Mediated Sup…
Dressed vs. Pairwise States, and the Geometric Phase of Monopoles and Charges
Csaba Csáki, Zi-Yu Dong, Ofri Telem +2
We construct the Faddeev-Kulish dressed multiparticle states of electrically and magnetically charged particles, incorporating the effects of real and virtual soft photons. We calc…
Monopoles Entangle Fermions
Csaba Csáki, Yuri Shirman, Ofri Telem +1
We resolve the decades old mystery of what happens when a positron scatters off a minimal GUT monopole in an s-wave, first discussed by Callan in 1983. Using the language of on-she…
The Radial Action from Probe Amplitudes to All Orders
Uri Kol, Donal O'connell, Ofri Telem
We extract the relativistic classical radial action from scattering amplitudes, to all orders in perturbation theory, in the probe limit. Our sources include point charges and mono…
The Phases of Non-supersymmetric Gauge Theories: the Case Study
Csaba Csáki, Andrew Gomes, Hitoshi Murayama +1
We investigate the IR phases of non-supersymmetric (non-SUSY) gauge theories with fermions in the vector representation obtained by perturbing the SUSY theory with…
Demonstration of Confinement and Chiral Symmetry Breaking in Gauge Theories
Csaba Csáki, Andrew Gomes, Hitoshi Murayama +1
We demonstrate that gauge theories with matter fields in the vector representation confine due to monopole condensation and break the chiral symmetry to $SO…
Some Exact Results in Chiral Gauge Theories
Csaba Csáki, Hitoshi Murayama, Ofri Telem
We analyze dynamics of chiral gauge theories based on the gauge group with one anti-symmetric tensor and anti-fundamentals when is odd. Based on the…
More Exact Results on Chiral Gauge Theories: the Case of the Symmetric Tensor
Csaba Csáki, Hitoshi Murayama, Ofri Telem
We study dynanics of gauge theories with fermions in rank-2 symmetric tensor and anti-fundamental representations, by perturbing supersymmetric theories with anomaly-…
Multi-particle Representations of the Poincaré Group
Csaba Csáki, Sungwoo Hong, Yuri Shirman +2
In this work we extend the definition of asymptotic multi-particle states of the -matrix, beyond the direct products of one-particle states. We identify new quantum numbers whic…
Axion strings are superconducting
Hajime Fukuda, Aneesh V. Manohar, Hitoshi Murayama +1
We explore the cosmological consequences of the superconductivity of QCD axion strings. Axion strings can support a sizeable chiral electric current and charge, which alters their…
Scattering Amplitudes for Monopoles: Pairwise Little Group and Pairwise Helicity
Csaba Csaki, Sungwoo Hong, Yuri Shirman +3
On-shell methods are particularly suited for exploring the scattering of electrically and magnetically charged objects, for which there is no local and Lorentz invariant Lagrangian…
Self Destructing Atomic DM

These lectures provide a self-contained introduction to the essential aspects of non-supersymmetric beyond the Standard Model (BSM) physics for beginning graduate students who are…
Continuum Naturalness
