The model meets the new data and muon neutrino trident scattering
Ming-Wei Li, Xiao-Gang He, Andrew Cheek +1
The Muon collaboration at Fermilab has announced their final result of the anomalous magnetic moment of the muon. By adopting the lattice-QCD evaluation of the leading-order…
Using to constrain preferred axion model dark matter
Andrew Cheek, Ui Min
Preferred axion models are minimal realizations of the Peccei-Quinn solution to the strong CP problem while providing a dark matter candidate. These models invoke new heavy quarks…
Axion Dark Matter Archaeology with Primordial Gravitational Waves
Andrew Cheek, Anish Ghoshal, Debarun Paul
We investigate the complementary information to be gained from inflationary gravitational wave (IGW) signals and searches for QCD axion dark matter. We focus on post-inflationary P…
Testing the dark origin of neutrino masses with oscillation experiments
Andrew Cheek, Luca Visinelli, Hong-Yi Zhang
The origin of neutrino masses remains unknown to date. One popular idea involves interactions between neutrinos and ultralight dark matter, described as fields or particles with ma…
A Direct Detection View of the Neutrino NSI Landscape
Dorian W. P. Amaral, David Cerdeno, Andrew Cheek +1
In this article, we study the potential of direct detection experiments to explore the parameter space of general non-standard neutrino interactions (NSI) via solar neutrino scatte…
Gemini Dark Matter
Andrew Cheek, Yu-Cheng Qiu, Liang Tan
The tension in the large scale structure can be explained by decaying dark matter with an almost degenerate spectrum and small enough decay width. Here we propose the Ge…
Extending preferred axion models via heavy-quark induced early matter domination
Andrew Cheek, Jacek K. OsiÅski, Leszek Roszkowski
We examine the cosmological consequences of the heavy quarks in KSVZ-type axion models. We find that their presence often causes an early matter domination phase, altering the evol…
Dark matter production through a non-thermal flavon portal
Andrew Cheek, Jacek K. OsiÅski, Leszek Roszkowski +1
The Froggatt-Nielsen (FN) mechanism provides an attractive way of generating the determined fermion mass hierarchy and quark mixing matrix elements in the Standard Model (SM). Here…
Earth rotation turns event timing into a geometric probe of UHE neutrino origin
Andrew Cheek, João Paulo Pinheiro, Jordi Salvado
It has been proposed that the ultra-high-energy (UHE) event detected by KM3NeT could be explained by dark matter (DM) decay. Prima facie this seems unlikely becau…
Redshift Effects in Particle Production from Kerr Primordial Black Holes
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
When rotating primordial black holes evaporate via Hawking radiation, their rotational energy and mass are dissipated with different dynamics. We investigate the effect of these dy…
Isospin-violating dark matter at liquid noble detectors: new constraints, future projections, and an exploration of target complementarity
Andrew Cheek, Darren D. Price, Ellen M. Sandford
There is no known reason that dark matter interactions with the Standard Model should couple to neutrons and protons in the same way. This isospin violation can have large conseque…
: Solar Neutrinos for Direct Detection
Dorian W. P. Amaral, David Cerdeño, Andrew Cheek +2
We introduce Solar Neutrinos for Direct Detection (): an open-source Python package that enables the computation of the solar neutrino rate spectrum at direct detec…
Primordial Black Hole Evaporation and Dark Matter Production: II. Interplay with the Freeze-In/Out Mechanism
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
We study how the evaporation of primordial black holes (PBHs) can affect the production of dark matter (DM) particles through thermal processes. We consider fermionic DM interactin…
The dark matter component of the Gaia radially anisotropic substructure
Nassim Bozorgnia, Azadeh Fattahi, Carlos S. Frenk +5
We study the properties of the dark matter component of the radially anisotropic stellar population recently identified in the Gaia data, using magneto-hydrodynamical simulations o…
Probing Dark Matter annihilation in the Galactic Centre with TRIDENT
Yingwei Wang, Xinhui Chu, Andrew Cheek +7
We determine the future sensitivity of the TRIDENT neutrino telescope to dark matter annihilation in the Galactic Centre. By applying the full detector design we show that TRIDENT…
Quality control for axions and ALPs
Andrew Cheek, Andrew Fowlie, Gonzalo Herrera
Axions and axion-like particles (ALPs) are protected by Peccei-Quinn (PQ) symmetries that quantum gravity is expected to break. Modeling quantum gravity by Planck-suppressed PQ-bre…
Primordial Black Holes Are True Vacuum Nurseries
Louis Hamaide, Lucien Heurtier, Shi-Qian Hu +1
The Hawking evaporation of primordial black holes (PBH) reheats the Universe locally, forming hot spots that survive throughout their lifetime. We propose to use the temperature pr…
Evaporation of Primordial Black Holes in the Early Universe: Mass and Spin Distributions
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
Many cosmological phenomena lead to the production of primordial black holes in the early Universe. These phenomena often create a population of black holes with extended mass and…
Light and Darkness: consistently coupling dark matter to photons via effective operators
Chiara Arina, Andrew Cheek, Ken Mimasu +1
We revise the treatment of fermionic dark matter interacting with photons via dimension-5 and -6 effective operators. We show how the application of the effective operators beyond…
Sub-GeV Dark Matter Under Pressure from Direct Detection
Andrew Cheek, Pablo Figueroa, Gonzalo Herrera +1
The DAMIC-M collaboration recently reported impressive bounds on sub-GeV dark matter, robustly testing both thermal and non-thermal models for the very first time. In this work we…
Dark photon dark matter from flattened axion potentials
Hong-Yi Zhang, Paola Arias, Andrew Cheek +3
Dark photons can be resonantly produced in the early universe via their coupling to an oscillating axion field. However, this mechanism typically requires large axion--dark photon…
Primordial Black Hole Evaporation and Dark Matter Production: I. Solely Hawking radiation
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
