The Very Nearly Right Theory of Flavor
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
The paper proposes a simple class of Yukawa matrix textures with nine non‑zero entries that naturally link the observed CKM unitarity‑triangle angles to multiples of π/8, offering…
Searches for GeV-Scale ALPs at RHIC
Kaori Fuyuto, Claudio Andrea Manzari, Hitoshi Murayama
We point out that ultra-peripheral Au+Au collision data collected at the Relativistic Heavy Ion Collider, operational during 2000-2026, can be used to search for axion-like particl…
Generating the fermion mass hierarchy at the TeV scale
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
We propose a class of theories to generate quark and lepton mass matrices where the scale of new physics is at the TeV scale, without inducing the large flavor and CP violating pro…
Clearing up the Strong problem
Joshua N. Benabou, Anson Hook, Claudio Andrea Manzari +2
The absence of a neutron electric dipole moment (EDM) constrains the quantum chromodynamics (QCD) theta angle to be less than one part in ten billion, posing the Strong proble…
Supernova axions convert to gamma-rays in magnetic fields of progenitor stars
Claudio Andrea Manzari, Yujin Park, Benjamin R. Safdi +1
It has long been established that axions could have been produced within the nascent proto-neutron-star formed following the type II supernova SN1987A, escaped the star due to thei…
The SN 1987A Cooling Bound on Dark Matter Absorption in Electron Targets
Claudio Andrea Manzari, Jorge Martin Camalich, Jonas Spinner +1
We present new supernova (SN 1987A) cooling bounds on sub-MeV fermionic dark matter with effective couplings to electrons. These bounds probe the parameter space relevant for direc…
