Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +368
Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high…
Gauging the cosmic ray muon puzzle with the Forward Physics Facility
Sergio J. Sciutto, Luis A. Anchordoqui, Carlos Garcia Canal +2
We investigate the observed muon deficit in air shower simulations when compared to ultrahigh-energy cosmic ray (UHECR) data. Gleaned from the observed enhancement of strangeness p…
Probing the Dark Dimension with Auger data
Neena T. Noble, Jorge F. Soriano, Luis A. Anchordoqui
[Abridged] By combining swampland conjectures with observational data, it was recently noted that our universe could stretch off in an asymptotic region of the string landscape of…
Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021
Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…
An explanation of the muon puzzle of ultrahigh-energy cosmic rays and the role of the Forward Physics Facility for model improvement
Luis A. Anchordoqui, Carlos Garcia Canal, Felix Kling +2
We investigate the observed muon deficit in air shower simulations when compared to ultrahigh-energy cosmic ray (UHECR) data. Based upon the observed enhancement of strangeness pro…
Hunting super-heavy dark matter with ultra-high energy photons
Luis A. Anchordoqui, Corinne Berat, Mario E. Bertaina +17
At any epoch, particle physics must be open to completely unexpected discoveries, and that is reason enough to extend the reach of searches for ultra-high energy (UHE) photons. The…
Prospects for macroscopic dark matter detection at space-based and suborbital experiments
Luis A. Anchordoqui, Mario E. Bertaina, Marco Casolino +12
We compare two different formalisms for modeling the energy deposition of macroscopically sized/massive quark nuggets (a.k.a. macros) in the Earth's atmosphere. We show that for a…
Through the Looking-Glass with ALICE into the Quark-Gluon Plasma: A New Test for Hadronic Interaction Models Used in Air Shower Simulations
Luis A. Anchordoqui, Carlos Garcia Canal, Sergio J. Sciutto +1
Recently, the ALICE Collaboration reported an enhancement of the yield ratio of strange and multi-strange hadrons to charged pions as a function of multiplicity at mid-rapidity in…
Hunting for super-heavy dark matter with the highest-energy cosmic rays
Esteban Alcantara, Luis A. Anchordoqui, Jorge F. Soriano
In 15 years of data taking the Pierre Auger Observatory has observed no events beyond GeV. This null result translates into an upper bound on the flux of ultrahigh-ener…
Probing strong dynamics with cosmic neutrinos
Luis A. Anchordoqui, Carlos Garcia Canal, Jorge F. Soriano
IceCube has observed 80 astrophysical neutrino candidates in the energy range 0.02 < E_ν/PeV < 2. Deep inelastic scattering of these neutrinos with nucleons on Antarctic ice sheet…
Isotropic charged cosmologies in infrared-modified electrodynamics
Jorge F. Soriano, Antonio L. Maroto
It has long been known that the covariant formulation of quantum electrodynamics conflicts with the local description of states in the charged sector. Some of the solutions to this…
Probing QCD approach to thermal equilibrium with ultrahigh energy cosmic rays
Jorge F. Soriano, Luis A. Anchordoqui, Thomas C. Paul +1
The Pierre Auger Collaboration has reported an excess in the number of muons of a few tens of percent over expectations computed using extrapolation of hadronic interaction models…
New test of Lorentz symmetry using ultrahigh-energy cosmic rays
Luis A. Anchordoqui, Jorge F. Soriano
We propose an innovative test of Lorentz symmetry by observing pairs of simultaneous parallel extensive air showers produced by the fragments of ultrahigh-energy cosmic ray nuclei…
