Mapping and Probing Froggatt-Nielsen Solutions to the Quark Flavor Puzzle
Claudia Cornella, David Curtin, Ethan T. Neil +1
The Froggatt-Nielsen (FN) mechanism is an elegant solution to the flavor problem. In its minimal application to the quark sector, the different quark types and generations have dif…
Heavy QCD axion dark matter from avoided level crossing
David Cyncynates, Jedidiah O. Thompson
The QCD axion offers a natural resolution to the strong CP problem and provides a compelling dark matter candidate. If the QCD axion constitutes all the dark matter, the simplest m…
Measuring axion gradients with photon interferometry (MAGPI)
Michael A. Fedderke, Jedidiah O. Thompson, Raphael Cervantes +5
We propose a novel search technique for axions with a -violating monopole coupling to bulk Standard Model charges . Gradients in the static axi…
Towards a nonperturbative construction of the -matrix
Brian Henning, Hitoshi Murayama, Francesco Riva +2
We present a nonperturbative recipe for directly computing the -matrix in strongly-coupled QFTs. The method makes use of spectral data obtained in a Hamiltonian framework and ca…
Nonperturbative structure in coupled axion sectors and implications for direct detection
David Cyncynates, Olivier Simon, Jedidiah O. Thompson +1
Pairs of misalignment-produced axions with nearby masses can experience a nonlinear resonance that leads to enhanced direct and astrophysical signatures of axion dark matter. In mu…
Dark QED from Inflation
Asimina Arvanitaki, Savas Dimopoulos, Marios Galanis +3
One contribution to any dark sector's abundance comes from its gravitational production during inflation. If the dark sector is weakly coupled to the inflaton and the Standard Mode…
Friendship in the Axiverse: Late-time direct and astrophysical signatures of early-time nonlinear axion dynamics
David Cyncynates, Tudor Giurgica-Tiron, Olivier Simon +1
A generic low-energy prediction of string theory is the existence of a large collection of axions, commonly known as a string axiverse. Axions also have a natural cosmological prod…
The Large-Misalignment Mechanism for the Formation of Compact Axion Structures: Signatures from the QCD Axion to Fuzzy Dark Matter
Asimina Arvanitaki, Savas Dimopoulos, Marios Galanis +3
Axions are some of the best motivated particles beyond the Standard Model. We show how the attractive self-interactions of dark matter (DM) axions over a broad range of masses, fro…
Classical gluon and graviton radiation from the bi-adjoint scalar double copy
Walter D. Goldberger, Siddharth G. Prabhu, Jedidiah O. Thompson
We find double copy relations between classical radiating solutions in Yang-Mills theory coupled to dynamical color charges and their counterparts in a cubic bi-adjoint scalar fiel…
A spartan model for the LHC diphoton excess
Thomas Appelquist, James Ingoldby, Maurizio Piai +1
We propose a simple model accommodating the reported 750 GeV diphoton excess seen in the first 13-TeV run of the LHC. It leads to testable predictions, in particular for di-lepton…
