The Very Nearly Right Theory of Flavor
Nima Arkani-Hamed, Carolina Figueiredo, Lawrence J. Hall +1
A striking empirical observation about the CKM matrix is that the angles of the unitarity triangle are very close to , simple fractions of that…
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…
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…
Resonant Landau-Zener Conversion In Multi-Axion Systems
David I. Dunsky, Claudio Andrea Manzari, Pablo Quílez +2
Multiple axions may emerge in the low-energy effective theory of Nature. Generically, the potentials describing these axion fields are non-diagonal, leading to mass mixing between…
Two Higgs Doublet Solutions to the Strong CP Problem
Quentin Bonnefoy, Lawrence J. Hall, Claudio Andrea Manzari +1
We solve the strong CP problem in a broad class of two Higgs doublet theories that will be probed at the Large Hadron Collider and at future colliders. These theories feature CP an…
Time-delayed gamma-ray signatures of heavy axions from core-collapse supernovae
Joshua N. Benabou, Claudio Andrea Manzari, Yujin Park +3
Heavy axions that couple to both quantum electrodynamics and quantum chromodynamics with masses on the order of MeV - GeV and high-scale decay constants in excess of G…
Strong CP and Flavor in Multi-Higgs Theories
Lawrence Hall, Claudio Andrea Manzari, Bea Noether
We introduce a class of multi-Higgs doublet extensions of the Standard Model that solves the strong CP problem with profound consequences for the flavor sector. The Yukawa matrices…
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…
On-shell recursion and holomorphic HQET for heavy quark hadronic resonances
Claudio Andrea Manzari, Dean J. Robinson
We develop a new theoretical framework for the treatment of heavy quark (HQ) resonances within heavy quark effective theory (HQET). This framework uses on-shell recursion technique…
Dark Matter in A Mirror Solution to the Strong CP Problem
Quentin Bonnefoy, Lawrence Hall, Claudio Andrea Manzari +2
We study thermal production of dark matter (DM) in a realization of the minimal models of Ref.~\cite{Bonnefoy:2023afx}, where parity is used to solve the strong CP problem by trans…
Supernova Limits on Muonic Dark Forces
Claudio Andrea Manzari, Jorge Martin Camalich, Jonas Spinner +1
Proto-neutron stars formed during core-collapse supernovae are hot and dense environments that contain a sizable population of muons. If these interact with new long-lived particle…
A Colorful Mirror Solution to the Strong CP Problem
Quentin Bonnefoy, Lawrence Hall, Claudio Andrea Manzari +1
We propose theories of a complete mirror world with parity (P) solving the strong CP problem. P exchanges the entire Standard Model (SM) with its mirror copy. We derive bounds on t…
Consistency and Interpretation of the LHC (Di-)Di-Jet Excesses
Andreas Crivellin, Claudio Andrea Manzari, Bruce Mellado +1
ATLAS observed a limit for {the cross section of di-jets resonances, which is weaker than expected for a} mass slightly below 1\TeV. In addition, CMS reported hints for th…
Comprehensive Analysis of Charged Lepton Flavour Violation in the Symmetry Protected Type-I Seesaw
Andreas Crivellin, Fiona Kirk, Claudio Andrea Manzari
The type-I seesaw model is probably the most straightforward and best studied extension of the Standard Model that can account for the tiny active neutrino masses determined from n…
A Flavour Inspired Model for Dark Matter
Claudio Andrea Manzari, Stefano Profumo
The discrepancies between data on rare -hadron decays, controlled by the underlying neutral-current transitions , and the corresponding Standar…
Snowmass2021 Cosmic Frontier: The landscape of low-threshold dark matter direct detection in the next decade
Rouven Essig, Graham K. Giovanetti, Noah Kurinsky +90
The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in the past few years. We summarize the science case for these searches, the recent progress,…
Towards excluding a light explanation of
Andreas Crivellin, Claudio Andrea Manzari, Wolfgang Altmannshofer +3
The discrepancies between data and the corresponding Standard Model predictions constitute the most significant hints for new physics (at the TeV scale or belo…
Unified Explanation of the Anomalies in Semi-Leptonic decays and the Mass
Marcel Algueró, Andreas Crivellin, Claudio Andrea Manzari +1
The discrepancies between the measurements of rare (semi-)leptonic decays and the corresponding Standard Model predictions point convincingly towards the existence of new physi…
Explaining the Cabibbo Angle Anomaly
Claudio Andrea Manzari
The Cabibbo-Cobayashi-Maskawa (CKM) matrix parametrizes the misalignement between the up- and down-quark mass basis in the Standard Model (SM). The observation of first row CKM uni…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
