Ultra-high-energy cosmic rays

LA Anchordoqui - Physics Reports, 2019 - Elsevier
In this report we review the important progress made in recent years towards understanding
the experimental data on ultra-high-energy (E≳ 1 0 9 GeV) cosmic rays. We begin with a …

Hunting for superheavy dark matter with the highest-energy cosmic rays

E Alcantara, LA Anchordoqui, JF Soriano - Physical Review D, 2019 - APS
In 15 years of data taking, the Pierre Auger Observatory has observed no events beyond 1 0
11.3 GeV. This null result translates into an upper bound on the flux of ultrahigh-energy …

Studies of an air-shower imaging system for the detection of ultrahigh-energy neutrinos

AN Otte - Physical Review D, 2019 - APS
We discuss the acceptance and sensitivity of a small air-shower imaging system to detect
earth-skimming ultrahigh-energy tau neutrinos. The instrument we study is located on top of …

Bounds on extra dimensions from micro black holes in the context of the metastable Higgs vacuum

KJ Mack, R McNees - Physical Review D, 2019 - APS
We estimate the rate at which collisions between ultrahigh-energy cosmic rays can form
small black holes in models with extra dimensions. If recent conjectures about false vacuum …
