A Comprehensive Interpretation of the LZ High-Energy Recoil Event: A Minimal Dark Sector and Its Experimental Tests
Mattia Di Mauro
The keV nuclear-recoil candidate reported by LUX-ZEPLIN (LZ) motivates an inelastic dark matter (DM) interpretation, in which scattering converts the DM particle into a sligh…
A possible interpretation of the LUX-ZEPLIN recoil event in the 2HD+a scenario
Giorgio Arcadi, Mattia di Mauro, Abdelhak Djouadi +1
It is tantalizing to consider the recent observation of the LUX-ZEPLIN (LZ) experiment of a high energy nuclear recoil candidate at keV as the long-awai…
Testing Higgs-Coupled Minimal Dark Matter with Solar Neutrinos after the LZ High-Recoil Event
Mattia Di Mauro
The LUX-ZEPLIN (LZ) Collaboration has reported a nuclear-recoil candidate at keV, motivating interpretations in terms of endothermic dark matter (DM). We investigate this sig…
Solar Capture Tests of Inelastic Dark Matter after the LZ High-Recoil Event
Mattia Di Mauro, Halim Shaikh
The LUX-ZEPLIN (LZ) Collaboration has reported a keV nuclear-recoil candidate for which endothermic dark matter (DM) gives some of the largest local significances. We study S…
Dark Matter at the Kinematic Edge: Interpreting the 248 keV LZ Nuclear-Recoil Candidate
Mattia Di Mauro
The LUX-ZEPLIN (LZ) Collaboration recently reported one event consistent with a keV nuclear recoil in a tonne-year exposure, with a maximum local significance of $3.4σ…
A geometric origin for the radiative neutrino portal to secluded dark matter
Mattia Di Mauro
We study a secluded dark-matter scenario in which the smallness of laboratory signals is linked to the origin of neutrino masses. In the four-dimensional theory, the dark sector co…
Refined anti-proton and anti-deuteron fluxes from weak-scale Dark Matter
Marco Cirelli, Mattia Di Mauro, Arpan Kar
We provide the cosmic-ray (CR) fluxes of antiprotons and antideuterons produced by the Galactic annihilation or decay of weak-scale dark matter (DM) particles of masses in the rang…
Legacy analysis of Milky Way dwarf spheroidal satellite galaxies: an update
A. Circiello, M. Di Mauro, M. Ajello +3
Studies of Fermi-Large Area Telescope (LAT) data coincident with dwarf spheroidal satellite galaxies (dSphs) of the Milky Way (MW) have put the most stringent constraints on models…
A Precise Measurement of the Fermi-LAT Galactic Center Excess Morphology and Spectrum
Mattia Di Mauro
We present a new Fermi-LAT analysis of the Galactic-center excess (GCE) designed to substantially reduce the dominant systematic uncertainties associated with interstellar-emission…
Strong Constraints on Millisecond Pulsar Injection Spectra from Fermi-LAT Observations of the Galactic Center
Jordan Koechler, Pedro De la Torre Luque, Mattia Di Mauro
Millisecond pulsars (MSPs) are a leading explanation of the Galactic Center excess (GCE) observed in Fermi-LAT data. We constrain this scenario by jointly modeling prompt and inver…
Revisiting predictions for cosmic-ray antinucleon fluxes from Galactic Dark Matter
Lorenzo Stefanuto, Mattia Di Mauro, Fiorenza Donato +3
The data on cosmic antiprotons have reached an outstanding precision on energies spanning from GeV to hundreds of TeV, thanks to the space-based AMS-02 experiment. The balloon-born…
Proton-Proton to Antinucleon Cross Sections for Cosmic Ray Applications
Mariaelena Boglione, Mattia di Mauro, Fiorenza Donato +3
We present predictions of inclusive antiproton and antineutron production cross sections in proton-proton collisions relevant to primary and secondary antiproton production in cosm…
Vector Higgs-Portal Dark Matter: How UV Completion Reopens Viable Parameter Space
Halim Shaikh, Mattia Di Mauro
The particle nature of dark matter (DM) remains one of the central open problems in modern physics. Among the most extensively studied candidates are weakly interacting massive par…
Toward universal coalescence models for antideuteron production
Mattia di Mauro, Jordan Koechler, Lorenzo Stefanuto +3
Cosmic-ray (CR) antinuclei, especially antideuteron and antihelium-3 nuclei , are among the most promising messengers for indirect dark ma…
Addressing the Impact of Solar Modulation Systematic Uncertainties on Cosmic-Ray Propagation Models
Isabelle John, Alessandro Cuoco, Mattia Di Mauro
We perform a comprehensive analysis of cosmic-ray propagation using the time-dependent AMS-02 flux measurements covering a full solar cycle, with particular emphasis on the role of…
